VEGETABLE FHYSIOLOCY AND AGRICULTURE. 681 Chemistry of Vegetable Physiology and Agriculture. Critical Observations on the Theory of Fermentation. (I). By ANDREAS RICHTER (Centr. Bukt. Pcw. 11 1902 8 787-796).- An examination of the ratio of carbon dioxide produced to oxygen consumed by yeast during an alcoholic fermentation of sugar in presence of peptone shows that during the early stages this ratio is about 1 but that it then increases considerably remains high until all the sugar has been fermented and again falls generally to about 0.6. It appears probable that at first the yeast cells simply grow without producing fermentation ; zymase is then developed in them and fermentation proceeds to the end after which the cells again simply make use of the nutriment still present (alcohol o r peptone) for purposes of growth.The theory of Iwanowsky (Diss. St. Petersburg 1894) that alcoholic fermentation is a pathological phenomenon in the nourishment of yeast brought about as a result of the abnormal composition of the nutrient liquid is therefore groundless A. H.682 ABSTRACTS OF CHEMICAL PAFERS. Cultivation of Bacillus Leprze. By G. VAN HOUTUM (J. Path. Bact. 1903 8 260-275).-A method of successfully cultivating the bacillus of leprosy is described. The ' sensibiliser ' which attaches itself to the bacilli only occurs in leper serum. The susceptibility of the bacilli to the action of leper serum explains the numerous failures t o cultivate them. W. D. H. Bacteriology of soil. By THEODOR REm (Centr. Baht. Peer. 11 1902 8 657-662 699-705 728-735 761-769).-Four soils of different origins were carefully compared as regards (1) chemical and physical composition ; (2) behaviour towards peptone solution (putre- factive power) the percentage of the total nitrogen which could be liberated by magnesia after varying times being estimated ; (3) capacity for producing nitrates ; (4) capacity for destroying nitrates ; (5) power of utilising the nitrogen of albumin ammonium sulphate and sodium nitrate in the production of vegetation and (6) total number of bacteria present a t different periods of the growth of vegetation.As a result it was found that the putrefactive nitrate-forming and nitrate-destroying powers of the soil stood in a very direct relation to the power of the soil to utilise the nitrogen of different types of nitro- genous manures in the production of vegetation.The number of bacteria present on the other hand afforded no indication of the degree of fertility of the soil. It was also found that a soil which was of very low fertility could not be greatly improved by the simple inoculation of bacteria of the type which was lacking. A. H. Influence of Varying Amounts of Carbon Dioxide in the Air on the Photosynthetic Process of Leaves and on the Mode of Growth of Plants. By HORACE T. BROWN and F. ESCOMBE (Proc. Boy. Soc. 1902 70 397-413).-Several varieties of plants were grown in ordinary air containing 3.29 parts of carbon dioxide per 10,000 and in air containing about three and a half times more carbon dioxide (11.47 per 10,000). The effect of the larger amount of carbon dioxide became in most cases apparent within a week or ten days and then rapidly increased.There was usually an increased number of internodes and coincidently a shortening of the internodes so that the height of the plants was not essentially altered. A characteristic result was the development of secondary axes in the axils of the leaves giving the plants a more bushy appearance. The area of the individual leaves was a good deal reduced and the leaves were frequently curled inwards which suggests an attempt on the part of the plant to reduce the excessive absorption of carbon dioxide by diminishing the exposure to light. Under the influence of an increased supply of carbon dioxide the leaves assumed a darker colour and accumulated much larger amounts of starch than under normal conditions.The most important result was the almost complete inhibition of inflorescence. Of the various plants experimented on Inapatiens pokatypetala suffered most severely in the earlier stages of growth losing nearly all its leaves A second growth of small very dark green leaves was how- ever produced.VEGETABLE PHYSIOLOGY AND AGRICULTURE. 683 Further experiments with air containing 6 per cent. of carbon dioxide gave similar results N. H. J. ill. Influence of Carbon Dioxide in the Air on the Form and Internal Structure of Plants. By J. BRETLAND FARMER and S. E. CHANDLER (Proc. Roy. Xoc. 1908,70 413-423).-The plants grown in ordirary air and in air containing an excess of carbon dioxide (see preceding abstract) were subjected to further examination attention being especially directed to the relative dimensions of the internodes the average relative areas of the leaves the number of stomata per' unit of area of leaf surface the anatomical differences and the relative amounts of starch &c.Except in the case of Kalancitoe Welwitsciki there was always an in- creased accumulation of starch in the leaves and ground parenchyma under the influence of an excess of carbon dioxide. I% KaZunchoe the ground cells of the stomata contained more starch than when grown under normal conditions whilst the amount of tannin was very much re- duced. The plants which under the usual conditions contain crystals of calcium oxalate contained less when grown in an excess of carbon dioxide except perhaps in the case of fuchsia. The experiments of E.C. Tkodoresco (Rev. Gen. Bot. 1899 2) which indicated greater luxuriance under the influence of excessive carbon dioxide differed materially from those described above none of the plants being grown in normal air but only in air free from carbon dioxide or in presence of 1.5 to 2 per cent. The air was moreover partially dried by means of sulphuric acid and this might tend to pro- mote transpiration. N. H. J. M. Certain Relations of Plant Growth to Ionisation of the Soil. By AMON B. PLOWMAN (Anzer. J. Xci. 1902 14 129-132).- A large number of pot and water-culture experiments were made in which the plants were subjected to the action of electricity. Platinum or more usually carbon electrodes were employed.I n the case of the soil experiments an excessive rise of temperature was avoided by addition of water ; in the water-culture experiments the temperature was kept down by means of cold water round the vessels. The results indicate that vegetable protoplasm is quickly killed by the conditions existing about the anode whilst within fairly broad limits it is stimulated by the conditions about the cathode. The effects observed cannot be attributed to the slight chemical changes due to dissociation and the electrical separation of the ions. N. H. J. M. Action of Chloroform Vapour on Resting Seeds. By B. SCHMID (Bied. Centy. 1902 31 646; from Ber. dewt. bot. Ges. 1901 19 7l).-Whilst chloroform vapour acts as a poison on the plasma the effect on dry seeds depends on the nature of the covering of the seeds.Garden cress was not injured by being kept for two months in air saturated with chloroform vapour whilst a small portion of the peas and wheat was destroyed in 24 hours. All the seeds when deprived of their skins were destroyed in 24 hours. N. H. J. M.684 ABSTRACTS OF CHEMICAL PAPERS Protein Grains in Oleaginous Seeds. By BILLE GRAM (Lm2dw. Versuchs-Stut. 1902 57 257-296).-The skins of protein grains mere generally found to resist the action of moderately strong aqueous potlash. I n some cases when the potash causes the skins t o burst sections boiled in alcohol may be employed. The grains contain a substance soluble in water and in alcohol and having the properties of cane sugar Ricinus globoids were found t o contain succinic acid in addition to the substances detected by Pfeiffer.The globoids of the other seeds examined seem to have the same chemical composition. The globoids of fennel contain magnesium and calcium phosphate malate and succinate and this probably holds good generally in the case of the proteids of umbelliferous plants. Crystalloids may occur as crystals or in rounded off forms in single seeds and they may be accompanied by proteid grains free from crys- talloids. N. H. J. 11. Ammonium as Direct Source of Nitrogen for Plants. By P. KOSSOWITSCH (J. exper. Landw. 1901 635-636).-The plan of the experiments was to grow peas manured respectively with am- monium sulphate and sodium nitrate under conditions of sterilisation. At the conclusion of the experiment it was found that the sterilisa- tion had not been completely maintained; both the plants and the nutritive solutions were however free from nitrates.The results showed that when manured with ammonium sulphate the peas grew as well as in presence of nitrate. The plants developedespecially well when ferric hydroxide was substituted for calcium carbonate (compare Maze Ann. Inst. Yasteur 1900 26). Formation of Asparagine in the Metabolism of Shoots. By U. SUZUKI (Bull. Colt. Agric. Tokyo hap. Univ. 1902 4,351-356). -The result's of experiments with barley and dry beans showed that whilst in cultivated shoots decomposition of protein takes place in absence as well as in presence of oxygen there was an increase of asparagine only when oxygen was present. Primary amino-compounds decrease with the production of asparagine.Amount of Lime Contained in Phanerogamic Parasites. By K. As6 (Bull. ColL Agric. Tokyo Imp. Uaiv. 1902,4 287-289).-The ash of Cuscuta europa contains only about 2 per cent. of lime whilst clover its host yields an ash with more than 30 per cent. This together with Palladius's observation that etiolated leaves of Viciu faba contained less lime than green leaves and the fact that seedlings generally require less lime before than after they have chlorophyll accords with the inference that not only the nuclei but also the chloro- phyll bodies require lime. I n this connection another non-chloro- phyllous plant Gastrodiu elaia was investigated. The dry matter of (1) the above ground and (2) the underground parts contained respectively 5.25 and 3.04 per cent.of ash of the following composition K,O. Na,O. CaO. MgO. Fe,O,. P,O,. SO,.

The results lend support to the view that the chlorophyll determines the ratio between lime and magnesia. N. H. J. M. The Colouring Matter .and the Sugars of Apricots. By A. DESMOULI~RE (Ann. Chirn. anal. 1902 7 323-324).-Apricots con- tain chiefly sucrose with a little invert sugar and also a small quantity of free dextrose which seems to become less when the fruit ripens.The colouring matter is extracted by amyl alcohol from either acid or ammoniacal solution. It is distinguished from coal-tar colours by not dyeing either wool or silk but i t is coloured blue on adding sul- phuric acid. Probably i t is closely related to crirrotene. L. DE K. Mucilage of the Prickly Pear (Opuntia vulgaris). By V. MARLAY (J. Phc~rm. Chini. 1902 [vi] 16 193 -198).-The muci- lage obtained from the cactus Optmtic~ vulgaris consists for the most part of araban and galactan ; its solution is dextrorotatory (+ 3 5 O ) and in its behaviour it more closely resembles the gums than the pectins. H. R. LE S. Amount of Oil in Cotton Seeds of Various Origins culti- vated in Central Asia.By D. TSCHERNEVSKY (J. Buss. Phys. Chm. SOC. 1902 34 503-504).-When grown in Central Asia cotton seeds from America or Egypt contain from 21.19 to 23.46 per cent. of oil whilst those from Bokhara have only 17.15-17T5 per cent. T. H. P. Oil of the Red Elderberry Sambucus Racemosa var. Arborescens. By H. G. BYERS and PAUL HOPKINS (J Amer. Chem. Soc. 1902 24 771 --774).-The oil extracted from the expressed juice of the berries by ether is of a light yellow colour which be- comes darker on exposure to light orheat. It has a sp. gr. 0.9072 at 15" solidifies at - 8" and melts a t 0". The oil contaius 6.65 per cent. of free acid calculated as oleic and yields on hydrolysis 11 *4 per cent. of glycerol which is originally present in the form of palmitin olein and linolein (?) with smali quantities of capriu caproin and caprylin.The unsaponifiable matter amounts to 0.66 per cent. The saponifica- tion number is 209.3 the iodine uumber 81.44 the Hehner number 9 1.75 and the Reichert-Meissl value 1.54. T. A. H. Composition of t h e Nuts of Gingko Biloba. By U. SUZUKI (Bull.

Indian Ipecacuanha. By BENJAMIN H. PAUL and ALFRED J. COWNLEY (Pharm. J. 1902 [iv] 15 256-257).-A sample of Indian ipecacuanha was found to contain emetine 1.39 cephaeline 0.50 and psychotrine 0.09 per cent. E. G. Chemistry of Solanum Dulcamara. By FREDERICK DAVIS (Pharm. J. 1902 [iv] 15 160-161).-An examination of ,Solanurn dulcamam has revealed the presence of solanine solanidine solanein and dulcamarin. The ripe fruit also contains 0-3-0.7 per cent. of malic acid. Solanine (m. p. 235O) solanidine (m. p. 2 0 5 O ) and solanein are represented by the f ormuls C,2H750,,N,C,,H7102N and C,,H7,O1,N respectively.E. G. Variation in the Occurrence of Salicin and Salinigrin in different Willow and Poplar Barks. By HOOPER A. D. JOWETT and CHARLES E. POTTEH (Pharm. J. 1902 [iv] 15 157-159).-1n order to determine the species of Xalix which yields salinigrin (Jomett Trans. 1900 77 707) a large number of species of Salix and Populu~ have been examined. Salinigrin was found in one case only Sulix discolor whilst salicin was detected in eight species but in only two of these was it present in sufficient quantity to be isolated. It was found that the amount of salicin contained in the bark of a willow or poplar depends not only on the species but also on the season of the year in which it is collected the sex of the tree and possibly other factors. E. G. Decomposition of Fodder and Food by Micro-organisms.11. Organisms Destroying Bread. By JOSEF KONIG ALB. SPIECKER- MANN and J. TILLMANS (Zeit. Nahi*. Genussm. 1902 5 737-763. Compare Abstr. 1901 ii 676).-The action on bread of Bacillus viscosus I and II and B. panis viscosus I Vogel was accompanied by de- composition of carbohydrates and nitrogenous substances starch being dextrinised. The fat and crude fibre appeared to be little attacked. As the result of the decomposition of the yroteids free ammonia was formed and the amount of soluble nitrogenous compounds increased. The acidity of the attacked bread also increased as compared with the original bread. Experiments on starch showed that the bacteria partially converted i t into dextrin and sugars. With yeast the same alterations were noticed as in the case of bread.An investigation was also carried out on the chemical nature of the ‘‘ ropiness ” of the bread which was produced by the bacteria. Estimations were made of the nitrogen water asb pentosans and other carbohydrates after separating the substances into two portions one soluble and the other insoluble in 50 per cent. alcohol. The former contained:VEGETABLE PHYSIOLOGY AND AGRICULTURE. 687 water 10.30 ; nitrogen 1.61 ; carbohydrates (after 6 hours’ inversion with hydrochloric acid) 42.50 ; pentosans 3.48 ; and ash 5.48 per cent. The insoluble portion contained water 4.49 ; nitrogen 8.80 ; carbo- hydrates (inverted) 16-74 ; pentosans 3.83 ; and ash 7.78 per cent. w. P. s. Sunflower Cake. By RICHARD WINDISCH (Landw.

Amounts of Potassium and Phosphoric Acid in the Ashes of Leaves of Varieties of Potatoes Rich in Starch By JOSEF SEISSL and EMANUEL GROSS (Chem. Centr. 1902 ii 383-384; from Zed.Landw. Yersuchswes. Oesterr. 5 862-875).-Potassiurri applied as kainite increased both the yield of tubers and the amount of starch. Superphosphate alone was injurious both as regards quantity and yield. When both manures were applied the injurious effect of superphosphate was diminished but not overcome. I n every case there was increased leaf production ; the leaves were light coloured and yellowish when phosphoric acid was applied (even when in conjunction with potash) but normal with kainite alone. The ash of leaves OF potatoes rich in starch contained more potassium and phosphoric acid than in the case of potatoes poor in starch. The difference was observed all through the vegetative period and with different manures. As regards the action of manures on the composi- tion of the leaf ash only phosphoric acid and in some cases potassium had any effect.Manurial Experiments with Forty per cent. Potassium Salts on Potatoes on Peat Soil. By BRUNO TACKE (Bied. Centr. 1902 31 584-585 ; from FZugbZatt. Brernen Dec. 1900).-Forty per cent. 6‘ potassium manure salts ” gave better results with potatoes than kainite. I n the case of newly cultivated peaty soil 175 to 150 kilos of potash may be applied whilst an application of about 100 kilos. per hectare will suflice for similar soil which has been longer cultivated. The best time for applying the salts for potatoes is towards the end of winter. Constituents of Emmenthaler Cheese. By ERNST WINTER- STEIN and J. THONY (Zeit. physiol. Chem. 1902,36 28-38.

The chief basic constituents which have so far been identified are histidine lysine pentamethylenediamine tetramethyl- enediamine and probably guanidine. Arginine has not been detected; i t is presumably formed but during the ripening process undergoes decomposition probably into guanidine and tetramethylenediamine. I n only one cheese a very old one has any appreciable amount of tyrosine been found and then it has a very low dextrorotation.J. J. S. Chemical Methods for Estimating the Fertility of Soils as regards Phosphoric Acid. By K. K. GEDROIZ (JOUY. exper. Lnndw. 1901 768-769).-Determinations of the phosphoric acid in soils were made by Maercker's method (action of 300 c,c. of 2 per cent. citric acid on 60 grams of soil for 24 hours) and by Eogdanoff's method (digesting 1 kilo. of soil for 24 hours with 4 litres of 2 per cent. acetic acid). At the same time pot experiments were made in which various plants were grown in the same soils. The results showed that the different plants took up unequal amounts of phos- phoric acid and that barley and flax assimilated amounts differing considerably from those dissolved by 2 per cent.acetic acid. On the whole citric acid gave better results than acetic acid. N. H. J. l!t. Solution of Phosphoric Acid in Soil Water. By G. PATUREL (Ann. Agron. 1902,28,385-398).-The total phosphoric acid and the phosphoric acid soluble in wilter (by extxacting 300 grams of soil with 1300 C.C. of water) both before and after addition of superphosphate (0.1 per cent,) was determined in six soils (1) calcareous clay (from lias) (2) sandy clay (3) sandy soil (derived from granite) (4) slightly calcareous sand ( 5 ) humous sand and ( 6 ) garden soil. The following results wme obtained CaCO,. per cent. 1 ......... 12.8 2 ......... 0.4 3 . . . ...... 0 5 4.... ..... 3.5 5 ......... 0.4 6 ......... 9.6 PZ05. 0.717 0.1 83 0.119 0.171 0.246 0.409 per cent.P,O soluble in water (mg. per litre).

The results obtained 1vit.h soil (5) are of interest as this is a typical hemp soil and hemp has a very short vegetative period and requires plenty of available food. The soilVEGETABLE PHYSIOLOGY AND AGRICULTURE. 689 (3) which gave the highest result is a vine soil which for years had given very good results when manured with superphosphate. Further experiments were made with the samples of this soil obtained five months after the application of superphosphate Although there had been much rain iince the manure mas applied the aqueous extract obtained after five months contained nearly 10 milligrams of phosphoric acid per litre.Action of Potasssium Manures on Peat Land. By ANTON BAUMANN (Ried. Centr. 1902 31 585 -589 ; from Vierteljcclmschr. Bayer. Landw. 1901 Heft. 1 ; and Arb. deut. Eandw. Ges. Heft. 56).- Potassium carbonate and sulphate are the best potassium manures for potatoes on peat soil and potassium chloride (K,O = 40-50 per cent.) is a much better manure than salts containing a low percentage of chlorine especially kainite. Eight years’ manuring with salts con- taining a high percentage of potassium without lime or marl was without injurious effect.Influence of different Ratios of Lime and Magnesia on the Development of Plants By K. As6 (Bull. Coll. Ayric. I’okyo Imp. Univ. 1908 4 361-370).-Soy beans require a greater excess of lime over magnesia than is the case with wheat barley and onions. The difference is attributed t o the greater leaf surface produced i n a given time by the beans. The proper rntio between lime and magnesia is of great practical importance and in liming a soil not only the amount of lime already present but especially its relation to the magnesia should be con- sidered. The poisonous effect of magnesia in absence of lime and the influence of the latter on the production of root hairs already observed by Loew were confirmed. To what extent should a Soil be Limed? By T.FURATA (Bull. COX Agric. Il’okgo Tw~p. Univ. 1902 4 371-379).-The most favourable ratios CitO/&IgO for buckwheat cabbage and oats were found to be 3 1 2 1 and 1 1 respeclively. Before liming a soil the readily available lime and magnesia should be determined after which lime should be added in such quantity as will give the desired ratio according t o the kind of crop to be grown. By OSCAR LOEW (Bull. CoZZ. Ayric. (I’okyo Imp. Uibiv 1902 4 38 1-385. Compare prececling abstracts and LQew and May this vol. ii 622)-In reference to the importance of lime to cereals especially before the flowering period i t is s-iggested that the application of a very dilute solution of calcium nitrate t o the young plants might be very beneficial.

690 ABSTRACTS OF CHEMICAL PAPERS. Analytical Chemistry. Filter-paper; a Source of Error in Chemical Analysis. (i) Retention of a Dissolved Substance by Filter-paper and by Cotton; (ii) Unequal Spreading of a Substance in Solution when placed on Filter-paper. By MANSIER (J. Phmm. Chim. 1902 [vi] 16 60-64; 116-120).-When solutions of solid sub- stances are filtered through filter-paper or cotton the filtered solution generally contains less OF the dissolved substance than it did before filtration owing t o the fact that the filter-paper or cotton absorbs a n appreciable amount of the dissolved substance. This is particularly the case with solutions of the alkalis sulphuric acid and the salts of tjhe alkaloids. Sodium chloride and certain other salts however are not thus absorbed.When a drop of the solution of a solid substance is placed on filter- paper the outer zone of the moistened portion is very often entirely free from the dissolved substance. These facts may in the author's opinion lead to serious errors in chemical analysis. HI. R LE S. Titration with Phenolphthalein in Alcoholic Solution. By ROBERT HIRSCH (Bey. 1902 35 2874-2877).-One hundred C.C. of neutral 96 per cent. alcohol containing 5 mg. of phenolphthalein is coloured only a pale rose by 0.1 C.C. of Nsodium hydroxide whereas in aqueous solution a n intense colour is developed. On heating the aqueous solution the colour fades but that of the alcoholic solution becomes much deeper. I n methyl alcoholic solution under similar con- ditions no colour appears. Warm solutions of normal sodium acetate and stearate in alcohol give a strong coloration with phenolphthalein ; consequently the reddening of an alcoholic solution of soap by phenol- phthalein cannot be used alone as an indication of the presence of free alkali.K. J. P. 0. Preparation of Standard Solutions of Sulphuric Acid by Electrolysis. By DAUVE (J. Pharm. Clt,im. 1902 [vi] 16 65-66). -The strength of a solution of sulphuric acid produced by the electrolysis of a neutral solution of copper sulphate cannot be deter- mined by weighing the copper deposited on the cathode because cuprous oxide is invariably deposited along with the metallic copper (compare H a r t and Croasdde J. a n d Chem. 1890,4 424). H. R. LES.ANALYTICAL CHEMISTRY. 691 Volumetric Estimation of Soluble Iodides. By E.RICHARD (J. Z'harm. Chim. 1902 Lvi] 16 207-209).-'l'en C.C. of a 1 per cent. solution of the iodide t o be estimated are mixed with 10 C.C. of a 0.5 per cent. solution of potassium iodate and 10 C.C. of a 4 per cent. solution of tartaric acid. The mixture is shaken and immediately treated with 20 C.C. of a 10 per cent. solution of disodium hydrogen phosphate and the free iodine titrated by means of a standard solu- tion of sodium thiosulphate. Tartaric acid is used in preference to all other acids because it has no action on chlorides or bromides in the cold. The sodium phosphate neutralises the free tartaric acid with production of sodium tartrate and sodium dihydrogen phosphate. H. R . LE S. Detection of Iodine and Bromine in the Presence of Thio- sulphates. By AUGUSTE F.LEUBA (Ann. Chim. anal. 1902 7 298-299).-The boiling solution is mixed with a slight excess of lend nitrate whiih after a few minutes precipitates the thiosulphate. Although the greater part of the iodine is also precipitated sufficient is left in the filtrate to apply the ordinary tests for iodine; the same process also applies t o the detection of bromine. Bromine however is best detected by adding to the solutlion a little sodium hydroxide and a little fluorescein which causes an intensely red coloration. L. DE K. Improved Reactions and Methods of Preparation of Ozone; Ursol D as a Reagent for Ozone. By CARL ARNOLD and CURT MENTZEL (Ber. 2902 35 2902-2907. Compare this vol. ii 352).-The violet reaction given by test papers of tetramethyldi-p- aminophenylmethane with ozone (Zoc.cit.) is shown to be obtained only when the ozone is quite free from acids. Traces of the latter pro- duce a blue or bluish-green reaction. Thus ozone prepared from barium peroxide containing nitrite or from persulphates or sodium per- oxide and sulphuric acid gives a blue reaction unless previously washed with alkali or the test papers moistened with a solution of a weak base ammonia &c. Ozone is best recognised in aqueous solu- tion by adding one or two drops of a methyl alcoholic solution of tetramethyldi-p-aminophenylmethane and 1-2 C.C. of an aqueous solution of silver nitrate or manganous sulphate. I n the presence of minute traces of permanganate or cerium sulphate which give a simi- lar colour reaction with the test it is necessary to add a saturated solution of ferrous sulphate before addition of the reagent. With river or well water manganous sulphate is preferable to silver nitrate. Hydrogen peroxide can be recognised in the presence of ozone by means of a solution of benzidine and copper sulphate which gives a blue precipitate with hydrogen peroxide but only a reddish-yellow precipitate with ozone.It has been demonstrated by this means that in neutral solution ozone and hydrogen peroxide have no action on one another. Details are given of the best methods of preparing ozone by the action of the dark electric discharge or of phosphorus on oxygen and by tLat of concentrated sulphuric acid on permanganate persulphate or barium or hydrogen peroxide.692 ABSTRACTS OF CHEMICAL PAPERS.It is shown that ‘‘ ursol D,” the reagent recommended by Chlopin (this vol. ii 582) for detecting ozone only gives a blue coloration in the presence of acids.

Xoc. 1902 34 457-461).-The author gives a modification of Antony and Lucchesi’s method (Abstr. 1899 ii 517) for estimating the sulphur in coal and pyrites which can be carried out in a comparatively short space of time. 0.5 Gram of the finely powdered coal is intimately mixed with 1 gram of manganese dioxide 0.5 gram of potassium carbonate and 0.5 gram of magnesium oxide and the mixture heated in an inclined platinum crucible by means of a gradually increasing flame.After a quarter to a half hour’s heating the crucible is allowed to cool and then with its-con- tents placed in a beaker of hot water to which is added 10 C.C. of concentrated hydrochloric acid ; the beaker is next heated until the mass dissolves the liquid being then neutralised with ammonia solu- tion t o precipitate the ferric hydroxide which is removed by filtering. Experiments made by the author show that by this means the silica is completely pyecipitated without requiring the long evaporation with hydrochloric acid. The liquid is finally heated to boiling and the sulphuric acid precipitated by means of barium chloride. The process may be still further shortened by using for the oxidation of 0.5 gram of coal a mixture of 1.5 granis of magnesium oxide and 1.5 grams of manganese dioxide.The estimation of bulphur in pyrites is carried ont in a similar way a mixture of 2 grams of manganese dioxide 1 gram of potassium carbonate and 1 gram of magnesiuni oxide being employed with 0.5 gram of the mineral. A series of parallel estimations shows t h a t the method gives results practically identical with those obtained by the use of the much slower process of Eschk:i (Chem. Zeit. 1892 16 1070). T. H. P. A Volumetric Method for the Estimation of Sulphuric Acid in Soluble Sulphates. By YASUJURO NIKAIDO ( J . Amev. Chena.

In the case of the sulphates of the heavy metals (iron zinc &c.) a little acetic acid should be added t o prevent the formation of basic sulphates. The titration -must be carried out in the cold. w.

L. DE K. Quantitative S e p a r a t i o n s by Persulphates in Acid Solution. By MAX DITTRICH and C. HASSEL (Bey. 1902 35 3266-3271).- Manganese is completely precipitated from a slightly acid (sulphuric or nitric acid) solution by boiling with ammonium persulphate. The precipitate settles well and can easily be filtered. Ammonium per- sulphate is better than potassium persulphate because i t decomposes more easily. Results are given which show that the method works well for the separation of manganese from magnesium zinc or a1 u m i n i um . The evaluation of persulphate is best carried out by heating with manganese sulphate and hydrochloric acid condncting the chlorine evolved into potassium iodide solution and then determining the amount of iodine separated.J. McC. By K. FRIEDRICH (Zeit. angew. Chem. 1902 15 852-856).-The selenium precipitate obtained in the nsual course is returned with the filter to the beaker and boiled with 10 C.C. of ammonia and 25 C.C. (or more) of N / l O silver nitrate. Black silver selenide is formed and sometimes a white deposit of silver selenite is obtained which however redissolves on adding more ammonia. When cold the liquid is acidified with dilute nitric acid (31.5 grams per litre) until any precipitate of silver selenite has redis- solved and the excess of silver is then estimated by Volhard’s thio- cyanate method.One C.C. of N/lO silver represents 0.005914 gram of selenium. The method becomes less accurate when the amount of Behaviour of Selenious Acid in the Marsh Apparatus. By IWAN SCHINDELMEISER (Zeit. ojentl. Chem. 1902 8,306-309).-0n adding 0.025 gram of selenious acid to the flask of a Marsh apparatus the evolution of hydrogen practically ceased the pieces of zinc being coated with a brown film and a flocculent brown-red precipitate appearing in the acid solution. This precipitate was found t o be a selenium-zinc compound containing from 11 t o 19 per cent. of zinc. When aluminium and sodium hydroxide solutions were employed selenious acid also caused the evolution of hydrogen to cease after a time. I n none of the experiments was a mirror obtained.Selenious acid and arsenious oxide were then introduced together into a Marsb apparatus. So long as selanious acid remained in solution no arsenical mirror formed but when the selenium had separated as a precipitate the arsenic came over. no trace remaining in the Comparative Estimations of Nitrogen by the Method of the Association [of Agricultural Experiment Stations] and the Gun- ning-Atterberg Modification of Kj eldahl’s Method.

In the Gunning-Atterberg modification the substance (1-2 grams) is heated for about 15 minutes with sulphuric acid (20 c.c.) and mercury (about 1 gram) Potassium sulphate (15-18 grams) is then added and the mixture boiled for about 15 minutes after it has become colourless.The potassium sulphate may be added at the commencement in the case of substances which do not froth. The results of a considerable number of determinations made at Bonn Danzig and Hohenheim showed that the two methods are equally trustworthy the difference in both cases being less than 0.1 per cent. of nitrogen in 95 per cent. of the analyses. Both potassium sulphate and phosphoric oxide quickened the decomposition and potassium sulphate had the advantage that i t does not attack the glass.I n one case it was found that the potassium sulphate contained nitrogen (0.0016G3 per cent.). N. H. J. M. Estimation of Nitric Acid in Water. By RUDOLF WOY (Zeit. bfeentl. Chew&. 1902 8 301-304).-The following modification of Devada’s method is described. Five hundred C.C. of the water are boiled in a round-bottomed flask of 800 c,c. capacity until the volume is reduced t o 100 C.C. After cooling the contents of the flask t o about 50° 1 gram of a n alloy consisting of aluminium 59 parts copper 39 parts and zinc 2 parts is added together with 5 C.C. of alcohol and 50 C.C. of sodium hydroxide solution (about 280 grams per litre). The flask is then connected to a condenser a bulb apparatus being placed between the two to prevent splashing over; the lower end of the condenser dips into a measured volume of standard acid.The contents of the flask are kept moderately warm for at least 30 minutes and then distilled 100 C.C. of distillate being collected. The excess of acid is titrated using congo-red as indicator and the number of C.C. of N/10 acid neutralised by the ammonia multiplied by 10.4 gives the milligrams of N,O per litre. The acid should be standardised by dis- tilling a known weight of ammonium chloride under the above condi- tions and a blank dihtillation with distilled water and the sodium hydroxide should be made to correct for any ammonia contained in the latter. w. P. s. Detection of very small Quantities of Arsenic.By GABRIEL BERTRAND (Bull. Soc. Chim. 1902 [iii] 27 851-S54).-The author describes the precautions which must be observed in order to detect very small amounts of arsenic (1/1000-1/2000 mg.) in Marsh’s appa- ratus. Small volumes of liquid are employed the apparatus is first freed from air by passing a current of carbon dioxide and the tube on which the arsenic deposit is to be obtained is of very small bore. A. F. Estimation of Minute Quantities of Arsenic. By CARL TH. MORNER (Zeit. anal.

The substance is distilled with fuming hydro- chloric acid the distillate received in dilute nitric acid and the solution evaporated to dryness.For the destruction of the organic matter which is invariably present in this distillate the residue while being warmed on the water-bath is treated with 2 C.C. of 5 per cent. potassium hydroxide (for 1 minute) 2 C.C. of 5 per cent. potassium permanganate (3 minutes) 2 C.C. of 5 per cent. sulphuric acid (3 minutes) and then with 1 C.C. of 20 per cent. tartaric acid and warmed until colourless. The solution is then filtered again heated and Fixed with 1 C.C. of a 5 per cent. solution of thioacetic acid. This precipi- tates the arsenic as trisulphide. After cooling the precipitate is col- lected on a 4 cm. filter of the best filter paper and washed five times with 2 C.C.of 0.5 per cent. sulphuric acid and three times with 2 C.C. of distilled water. The precipitate is then dissolved by pouring into the filter 2 C.C. of 0.5 per cent. potassium hydroxide solution (repeated three times) and the solution received in a flask containing 25 C.C. of N/100 permanganate. Oxidation to arsenic and sulphuric acids takes place iustantly ; the liquid is acidified with 5 C.C. of 5 per cent. sulphuric acid; a quantity of N/100 oxalic acid equivalent to the per- manganate is added and when the precipitated manganese peroxide has been dissolved by warming the residual oxalic acid is titrated with N/100 permanganate. A small correction (about 0.3 c.c.) is required for organic matter dissolved by the potassium hydroxide from the filter paper and is best estimated by making a blank experiment.In 40 test estimations with materials of the most varied character t o which 0.25 rug. of arsenic was added the result never differed by more than 0.05 mg. and in 29 of them by not more than 0.02 mg. from the quantity taken. One C.C. o i N/100 permanganate is equivalent to 0.0536 mg. of arsenic in the form of As,S,. Decomposition of Ores containing much Arsenic Iron and Lead with Sulphuric Acid. By H. NISSENSON and F. CROTOGINO (Chem. Zeit. 1902 26 847-849).-Ores coutaining sulphur and arseriic in combination with iron lead copper antimony zinc cobalt nickel &c. may be rapidly decomposed by heating the finely powdered sample with strong sulphuric acid in a round-bottomed flask for a time varying from half-an-hour to three hours; the end of the reaction may be readily judged from the appearance of the mass.When cold hot water is added which dissolves the arsenious acid and the soluble sulphates whilst the residue contains insoluble sulphates such as that of lead and compounds of antimony. The metals are then separated by well-known processes. The great advantage of the sulphuric acid treatment is that no arsenic is lost by volatilisation and also that it is obtained in a form readily precipitable by hydrogen sulphide. M. J. S. L. I)E K. Action of Boiling Hydrochloric Acid on Arsenic Acid.

Ferric chloride was also found to be reduced in the distilla- tion flask. Using nothing but ground-glass connections no formation of ferrous salt could be detected and in the arsenic experiments arsenic could not be discovered in the distillates by hydrogen sulphide. The Marsh-Berzelius test however gave plain indications of arsenic. As every precaution had been taken to cleanse the flask and condenser from organic matter the author considers this reduction to be due to the unavoidable presence of atmospheric dust.To prepare acid free from arsenic i t is better to add a powerful reducing agent then distil and only collect the distillates after all the arsenic has come over. w. P. s. Estimation of Boric Acid in Margarine. By ADOLF BEYTHIEN (Zeit Nalw. Genussm. 1902 5 764-766).-From 50 to 100 grams of margarine are weighed into a wide-necked flask and well shaken with 50 granis of hot water. As soon as partial separation has taken place the contents of the flask are filtered through a dry filter. The almost clear filtrate is cooled to the ordinary temperature and a portion (usually 40 C.C. can be obtained) is withdrawn by a pipette and neu- tralised with N/10 sodium hydroxide using phenolpht,halein as in dicator. Twenty-five C.C. of glycerol are then added and the titration completed.The A.jl0 sodium hydroxide should be standardised By PAUL THIBAULT and A. CH. VOURNASOS (Bull. SOC. Chim. 1902 [iii] 27 895-901).-In principle the method consists in heating the organic substance mixed with copper oxide (or copper oxide and lead chromate) in a vessel of cast irou to which the absorption apparatus is attached ; a side tube permits of a current of oxygen being passed into the vessel for the completion of the combustion. The authors claim great accuracy and expeditiousness for the method. Gasometric Method for Alkalimetry. By E. RIECILER (Zeit. anal. Chenz. 190.2 41 413-419).-The action of hydrazine sulphate on an iodate takes place according to the equation 6N2H,S0 + 4NaI03 = 2Ka2S0 + 4H,SO + 4HI + 1 2H20 + 6N2 whence 1 C.C. of nitrogen (at 0” and 760 mm.) corresponds with 5.2216 mg.of iodic acid or with 0.029’7 h’ mg. of a base of which E is the equivalent. If therefore a n alkali is accurately neutralised with iodic acid and the product treated with hydrazine sulphate in an azotometer the alkali can be estimated without the use of a standard acid. The author’s in- dicator diazonitroaniline can be used with ammonia as well as with the other alkalis when neutrnlising. Estimation of Calcium and Magnesium in Water. By ALBERT GRITTNER (Zeit. angew.

L. DE K. Estimation of Free Anhydrous and Hydrated Lime in Cements. By GEORGE W. MAYXARD (BuZI. floe. Chim. 1902 [iii] 27 858-882).-For the purpose of estimating the amount of free lime in cements the author extracts the cement with pure glycerol which has t,he property of dissolving the lime but not the other con- stituen ts of the cement. A. F. Double Ammonium Phosphates in Analysis. By MARTHA AUSTIN (Amel.. J. Sci. 1902 [iv] 14 156-158).-Dakin has pro- posed t o substitute ammonium phosphate for microcosmic salt when precipitating zinc or manganese as double ammonium phosphates in the presence of ammonium chloride.The precipitates are first washed with a 1 per cent. solution of ammonium phosphate and then with strong but not absolute alcohol. It appears from the author’s investigation t h a t the satisfactory results obtained by Dnkin are due to a compensation between the increase caused by tbe washing with alcohol and a loss due t o the slight solubility of the asbestos he has employed. When using suitable anhydrous asbestos the process as given by the author may be safely used for the estimation of magnesium manganese cadmium and zinc (Abstr. 1900 ii 49). L. DE K. Quantitative Separation of Zinc and Cobalt. By ARTHUR ROSENHEIM and ERNST HULDSCHINSKY (Zeit.anorg. Chem. 1902 32 84-90).-1n acetic acid solution zinc sulphide can be quantitatively precipitated and treated in the ordinary manner; very little cobalt is carried down by the zinc sulphide. Pot’assium cobaltinitrite precipitated from acetic acid in presence of zinc is never pure and the two metals cannot be satisfactorily separated by this means The best separation is effected by precipitating zinc sulphide from a solution of the mixed salts to ivhich potassium cyanide has been added in order t o form potassium cobalticyanide. The separation cannot be carried out by precipitating cobalt peroxide by means of potassium persulphate from a n alkaline solution because the precipitate always contains a consiJernble quantity of zinc hydroxide.J. McC. Application of Hydroxylamine and Hydraeine Salts in Qualitative Analysis. A New Separation in the Hydrogen Sulphide Group. By EMIL KNOEVENAGEL and ERrcrr EBLER (Bey. 1902 35 3055-3067).-0n account of the many difficulties of the separation of the metals of group 11 the authors have devised methods of separating these metals by means of hydrazine and hydroxy lamine and hydrogen peroxide I n the first process the precipitated sulphides are dissolved in a mixture of hydrochloric and nitric acids and after evaporation of the excess of acid the solution is diluted and dropped into a mixture of 20 per cent sodium hydroxide solution and saturated698 ABSTRACTS OF CHEMICAL PAPERS. hydrazine sulphate solution. The mixture is warmed diluted then filtered.The precipitate may contain metallic mercury or copper or the hydroxides of cadmium or bismuth whilst the filtrate may contain sodium arsenate sodium antimonate sodium stannate or sodium plumbate. A process is given for. identifying the metals in the pre- cipitate. I n the filtrate the lead is identitied by precipitation with hydrogen sulphide and the arsenic antimony and tin in the usual way. A second method is to dissolve the sulphides in a mixture of hydro- chloric and nitric acids evaporate to dryness and after the addition of 3-4 C.C. of nitric acid to pour into concentrated ammonia solution containing hydrogen peroxide. The precipitate obtained may contain lead as peroxide along with bismuth hydroxide and stmnic acid whilst the solution contains copper cadmium and mercury as soluble complex ammonium compounds and ammonium arsenate and anti- monate.The precipitate is treated with sodium carbonate and a little ammonium sulphide when the tin passes into solution. From the filtrate mercury can be separated by a hydrazine or hydroxylamine solution then on addition of magnesium chloride magnesium arsenate is precipitated. Copper is separated as thiocyanate cadmium as sul- phide by means of ammonium sulphide and on acidifying the anti- mony is precipitated as sulphide. The authors also describe the necessary modifications when platinum gold or molybdenum are present. J. McC. The Lake Superior Fire Assay for Copper. By GEORGE L. HEATH (J. Amr. Chem. Soc. 1902 24 699-708).-The method is only suitable for native copper occurring in veins or bedded deposits including the milled concentrates from the same and also any oxides carbonates or silicates of copper if entirely free from sulphur The carefully taken sample (1000 grains) is mixed with fused sodium car- bonate and borax (70 to 200 grains of each) and potassium hydrogen tartrate (300 t o 350 grains).To rich ores some old assay slag is added. The charge is fused in a closed crucible in a pot furnace the latter being brought to a high temperature before introducing the crucible. The fusion requires about 20 minutes and it is possible to tell by the eye the purity of the copper button and the waste (usually about 0.25 per cent.) in the slag. This waste is balanced by the presence of about 0.25 per cent. of iron in the button. W.P. S. Estimation of Copper by Potassium Permanganate. By H. A. GUESS (J. Amer. Chern. Soc. 1902 24 708-711).-The following method is stated to be at least. as accurate as either the cyanide or iodide method for the estimation of small or fractional percentages of copper in crude ores tailings &c. From 1 to 5 grams of the sample are digested with aqua regia with the addition of a few drops of sulphuric acid. The excess of acid is boiled off and the acid solution diluted and filtered. The filtrate is neutralised with ammonia rendered just acid by a few drops of hydrochloric acid and reduced by adding an excess of sodium sulphite. The copper is precipitated by either ammonium or potassium thiocyanate the solution being thenANALYTICAL CHEMISTRY. 69 9 boiled and decanted on to a filter (11 em.in diameter) as soon as the precipitate has settled. After bringing the precipitate on the filter it is well washed with hot water the funnel is placed over the original precipit:ttion flask and twice filled with 10 per cent. sodium hydroxide solution ; insoluble yellow cuprous hydroxide remains on the filter sodium thiocyanate passing through. The filter and precipitate are washed with hot water and the filtrate while still warm is titrated with standardised potawium permangana te solution after being first made decidedly acid with dilute sulphuric acid. As cuprous thio- cyanate is slightly soluble the permanganate solution should be standardised against pure copper treated as just described and the small error arising from the action of the filter paper on the hot sodium hydroxide solution corrected for by treating an empty filter under similar conditions and titrating the filtrate. w.P. s. Application of Eschka’s Method to Pig Iron. By JOHN V. R. STEHMAN (J. Amer. Chem. SOC. 2902 24 644-649).-The author applies the principle of Eschka’s sulphur estimation in coal &c. topig iron. Three grams of the powdered sample of a fineness exceeding 50 mesh are mixed in a 30 C.C. platinum crucible with 2.5 grams of basic mixture and the whole is then covered with another 0.5 gram of the mixture. This basic mixture is composed of 2 parts of magnesium oxide and 1 part of dry sodium carbonate or 4 parts of magnesium oxide 1 part of sodium carbonate and 1 part of potassium carbonate; the second mixture offers no advantage over the first.The crucible is then heated by means of a gasoline lamp for one hour at a full red heat. When cold the mass is broken up with a &ass rod placed in a beaker and extracted with hot water; 15 C.C. of bromine water are added and the whole is boiled for 15 minutes. To the filtrate which should be quite clear 1.5 C.C. of hydrochloric acid are added and after boiling off the bromine the sulphuric acid derived from the sulphur in the iron is then estimated as usual. Any sulphuric acid contained in the reagents should be allowed for. If ordinary coal gas is used as the source of heat care must be taken to prevent absorption of sulphurous fumes during the ignition. This is successfully prevented by using an asbestos board 8 inches by 4 inches ; in the centre of this board and near the lower edge a clean hole is cut of a size sufficient to admit the crucible.To the upper edge of this board is hinged by means of a copper wire a board of the same length but 3 inches wide and without any hole. This shield is then placed over the tripod in such a manner that when the crucible is put into place about seven-eighths of its length projects through the board and rests on the platinum triangle. The products of combustion from the gas then pass off above and away from the crucible. The results agree very well with those obt.ained by Blair’s standard method. L. DE K. Estimation of Iron. By F. SEILER and A. VERDA (Chem. Zeit. 1902 26 803-S04).-The authors obtained satisfactory results in the colorimetric estimation of small quantities of iron by means of potassium ferrocyanide or potassium thiocyanate but found that still700 ABSTRACTS OF CHEMICAL PAPERS.more correct results are got by operating as follows. The solution containing the iron as ferric chloride is diluted to 100 C.C. ; of this 10 C.C. are put into a cylinder mixed with excess of potassium thio- cyanate and diluted t o 50 C.C. Ten C.C. of the mixture are diluted with water until a clear red colour is obtained and a solution of potassium ferrocyanide (0.97 gram per litre) is then added until the colour of the liquid turns green. Each C.C. of ferrocyanide represents 0.0002 gram of iron. If only traces of iron are present there is no need for so much dilution. L. DE I(. Precipitation of Ammonium Vanadate by Ammonium Chloride By FRANK A.GOOCH and R. D. GILBERT (Amer. J. Xci. 1902 [iv] 14 205-210).-The authors have thought it necessary to make fresh experiments to determine whether ammonium meta- vanadate is insoluble in a completely saturated solution of ammonium chloride and have found that in the presence of a little free ammonia such is the case. The precipitate must be washed with a saturated solution of ammonium chloride and the vanadium may then be esti- mated in the residue by any appropriate means. Gibbs’s process (Amelr. Chem. J. 1883 5 371),based on the precipitation of vanadium as am- monium vanadate and titration of this with permanganate may therefore be safely used or Browning’s iodometric process may be employed. L. DE K. Precipitation of Ammonium Vanadate by Ammonium Chloride. By ARTHUR ROSENHEIM (Zeit.anorg. Chem. 1902 32 181-182).-The precipitation of ammonium vanadate by ammonium chloride is satisfactory for pure vanadate solutions but does not give sufficiently accurate results for the quantitative separation of vanadic and tungstic acids. J. McC. Solubility of the Sulphides of Arsenic Antimony and Tin. By WILLIAM R. LANG and C. M. CARSON (J. SOC. Chem. Ind. 1902 21 1018. Compare this vol. ii 530).-Continuing their experiments the authors tabulate the solubilities of the sulphides in various strengths of hydrochloric acid under different conditions and tempera- tures. They find that arsenious sulphide is insoluble in hydrochloric acid of sp. gr. 1-16 if hydrogen sulphide is passed into the mixture to saturation.Antimony trisulphide is soluble in a mixture of hydro- chloric acid of sp. gr. 1.16 (50 parts) aud wdter (18 parts) even when the solution is completely saturated n ith hydrogen sulphide. Stannous sulphide is soluble in hydrochloric acid slightly more dilute than that required to dissolve antimony trisulphide. To separate arsenious sulphide from antimony and tin sulphides the mixture should be treated with hydrochloric acid diluted with not more than one-third i t s volume of w:tter and then saturated with hydrogen sulphide. Arsenious sulphide remains insoluble and may be removed from the other two sulphides by filtration and washing with a mixture of hydrochloric acid and water (50 18) or with acid . containing hydrogen sulphide. w.P. s.ANALYTICAL CHEMISTRY. 701 Quantitative Separation of Zirconium and Iron. By ALEX- ANDER GUTBIER and G. HULLER (Zeit. anorg.

The mixture of ferric and zirconium oxides is ignited in a current of hydrogen; the ferric oxide is reduced t o metallic iron but the zirconium oxide is not affected. From the decrease in weight the amount of iron present can be calculated. Experimental numbers are given which show that the method is accurate. The method can also be used to determine iron and aluminium together since aluminium oxide suffers no reduction when heated in hydrogen.J. McC. Estimation of Platinum Gold and Silver in Alloys. By PERCY A. E. RICHARDS (Analyst 1902 27 265-268).-The following methods were found to give the most accurate results. a. Alloys containing Platinum and &Yver only.-About 0.3 gram of the alloy is heated with 10 C.C. of pure sulphuric acid until all apparent action has ceased. When cold the acid is decanted into a beaker containing cold water and the residue of metal again treated with sulphuric acid. After pouring off this acid (adding it to the first) the residue of platinum is washed with water (the washings being added to the silver sulphate solution) transferred to a crucible dried in the air-bath and weighed. The platinum retains t o some extent its original shape but has a blistered appearance.The silver in the acid filtrate is estimated by the thiocyanate method. b. Alloys containing Gold Platinum and &lveT.-The alloy is treated with sulphuric acid as just described the residue of gold and platinum being washed dried and weighed as a check. This residue-is then dis- solved in nitro-hydrochloric acid concentrated to a small bulk and the platinum separated as ammonium platinichloride. The gold in the filtrate is precipitated by ferrous sulphate washed dried and weighed. c. Alloys containing Bold Platinum Silver and (rin.-The silver and tin are separated by the sulphuric acid treatment just described the silver being afterwards titrated in the acid solution and the tin taken by difference. Fair results are also obtained by heating the alloy in a current of chlorine the tin chloride being volatilised and esti- mated by difference.Attempts to collect the tin chloride in water were not successful. w. P. s. Estimation of the Reducing Power of Natural Waters. By LUDWIG W. WINKLER (Zed. anal. Chin. 1902 41 419-426).-To estimate the amount of permanganate reduced by a natural water the author prefers to boil the water for 10 minutes with strongly alkaline permanganate partly because the oxidation of the organic matter is more complete in alkaline than in acid solutions and partly because with acid solutions percussive ebullition is scarcely to be avoided. To prepare the standard permanganate 50 grams of sodium hydroxide (purified by alcohol) are dissolved in 500 C.C. of water boiled for a VOL.

For use this solution is diluted five-fold and standardised with N/100 oxalic acid. When 10 C.C. of this solu- tion mixed with 100 C.C. of purified distilled water are boiled for 10 minutes a loss of oxygen equal to 0.175 C.C. takes place. As N/lW oxalic acid is employed for estimating the uureduced permanganate special experiments on the permanence of such a solution were made. When prepared with N/10 sulphuric acid instead of with water N/100 oxalic acid loses only 0.3 per cent. of its strength in 6 months. M. J. S. The Significance of Phosphates in Natural Waters. By A.

Xoc. 1902 24 735-743).-The conclusion arrived at is that the presence of phosphates in water in any quantity indicates pollution.Analyses of 42 samples of water including estimations of phosphoric acid confirm this statement. The amounts of phosphoric acid generally varied with the quantities of nitrates and chlorides although exceptions were found Less than 1 part of phos- phoric oxide per million is considered to be the limit for unpolluted waters. w. P. s. Fractional Combustion of Hydrogen Carbon Monoxide and isoPentane. By I(. W. CRARITSCHKOFF (J. RUM. Phys. Chern. Soc. 1902 34 461-465).-The author has carried out a number of experimea ts with mixtures of hydrogen and isopentane and of hydrogen and carbon monoxide the results obtained showing that Winkler's method of fractional combustion in presence of palladinised asbestos is totally inapplicable to the analysis of natural gas.It is also found that in presence of palladinised asbestos (1) Pure hydrogen undergoes complete combustion at 80° carbon monoxide at about 290° and isopentane at a temperature beyond 315O. (2) Nitro- gen and other indifferent gases are without influence on the temperature of combustion of hydrogen. (3) An admixture of carbon monoxide and isopentane considerably raises the temperature of combustion of hydrogen. (4) If hydrogen be mixed with an equal volume of isopentane it will burn slowly a t 200° 1.6 to 9.2 per cent of the isopentane also undergoing combustion a t the same time. (5) The speed of the reaction in the combustion of isopentane is very small and in order that the gas may be completely burnt it must be drawn many times over the strongly heated asbestos. (6) The above observations regarding isopentane also hold for carbon monoxide. T.H. P. Recognition of Aromatic Hydrocarbons. By EDUARD LIPPMANN and ISIDOR POLLAK (Monatsh. 1902 23 670-681).-0n addition of concentrated sulphuric acid and a few drops of benzylidene chloride the following hydrocarbons give characteristic colour reactions anthracene malachite-green ; naphthalene rosaniline ; benzene light yellow ; toluene light yellow ; phenanthrene carmine ; xylene orange ; triphenylmethane feeble yellow ; diphenylmethane brick-red ; stilbene blue-green ; 3/-cumene orange-red ; cymene orange ; pyrene emerald green becoming deep blue ; picene olive-ANALY TICdL CHEMISTRY.703 green the colour forming slowly ; dibenzylanthracene light green ; acenaphthene intense dark blue ; chrysene light yellow becoming light green and finally dark olive-green. Benzene toluene xylene $;cumene and cymene give the characteristic colour with sulphuric acid alone. G. Y. Examination of Alcoholic Liquids for Methyl Alcohol. By N. SCHOORL (Zeit. anal. Chem. 1902 41,426-428).-The author does not agree with Habermann and Oesterreicher that pure methyl alcohol reduces permanganate more rapidly than ethyl alcohol (this vol. ii l l O ) but attributes their result to the presence of traces of acetone and other easily oxidisable substances in the methyl alcohol which they employed. The Riche-Bardy and Trillat-Wolf methods are the only trustworthy ones for detecting small quantities of methyl alcohol in ethyl alcohol.M. J. S. Presence of Arsenic in Glycerol. By L~ONCE BARTHE (J. Pharm. Chim. 1902 [vi] 16 52-55).-Glycerol which is free from arsenic may on treatment with zinc and hydrochloric acid evolve a gas which reduces silver nitrate This test is therefore not a trustworthy one for the detection of arsenic in glycerol. Bougault’s method (this vol. ii 530) is very satisfactory and is applicable to the detection of arsenic in glycerol. Diagnosis of Pentosuria. By MANFRED BIAL (Chem. Cent?. 1902 ii 295; from Deutsch. med. Woch. 28 253-254).-Two or three C.C. of the urine suspected to contain peutose are mixed with 4-5 C.C. of a solution containing 1-1.5 grams of orcinol in 500 C.C. of fuming hydrochloric acid and then with 25 drops of a 10 per cent. solution of ferric chloride.After heating until bubbles just begin to form the liquid either at once deposits a green colouringmatter or turns green on cooling after 15-20 seconds. The process indicates the presence of pentose but not that of glycuronic acid. H. R. LE S. L. DE K. Pentoses in Urine. By ERNST KRAFT (Chem. Cent?. 1902 ii 482-483 ; Phccrm. Zeit. 47 522).-The author recommends the process used by Bial (see preceding abstract). 0.05 per cent. of pentose may be detected by it. L. DE K. Capillary Constants of Sugar Solutions. By A. DEMICHEL (Ann. Chim. and 1902 7 335-337).-A recalculation of the table constructed by the German Committee on Standard Weights for the correction of the specific gravity of sugar solutions owing to the capillary action of the liquid so as to suit the French requirement of knowing the amount of sugar in 100 C.C.and not in 100 grams of the solution. L. DE I(. The Phenylhydrazine Test f o r Sugar. By ALBERT B. LYONS (Pharm. Rev. 1902 20 155-158).-A criticism of the various modifications of the phenylhydrazine test for dextrose in urine pro- posed from time to time. 4’7-2704 ABSTRACTS OF CHEMICAL PAPERS. I n some cases the author thinks it advisable to first remove urates and phosphates. To 8 C.C. of the urine are added 1 C.C. of N-barium chloride and a few drops of N-potassium hydroxide. After filtering 0.2 gram of sodium carbonate is added and the liquid boiled and again filtered. To 5 C.C. of the filtrate 2 C.C. of acetic acid are added and the test with phenylhydrazine may then be applied L.DE I(. Estimation of Sugar by Fermentation. By ALBEBT B. LYONS (Pham. Rev. 1902 20 104-108).-The saccharine liquid containing from 0.2 to 1.5 grams of sugar is mixed with 2 grams of compressed yeast and introduced into a 50 C.C. fermentation flask which is then quite filled with water. The carbon dioxide is collected in a graduated cylinder which it enters from above and to prevent absorption the surface of the water is covered with paraffin oil. The liquid is allowed to ferment for at least 24 hours a t 25-30' An amount of carbon dioxide equal in volume t o the liquid should be added to that collected in the cylinder. If the amount of sugar is very small the carbon dioxide may practically all remain in solution ; in such a case a known weight of sugar should be added. I n accurate analyses the precise amount of carbon dioxide evolved from a known weight of sugar and the amount retained by the liquid may easily be ascertained by direct experiment The process is particularly recom- mended for the estimation of sugar in urine.L. DE K. Testing for Mannose. By FRANCIS H. STORER (Bull. Bumey Inst. 1902 3 13-45).-Twenty grams of finely powdered wood are boiled with 200 C.C. of 5 per cent. hydrochloric acid for three hours filtered and neutralised with sodium hydroxide solution (1 8). One C.C. of the solution is then treated with 12 drops of a solution obtained by dissolving 0.5 gram of phenylhydrazine hydrochloride in 5 C.C. of water and adding 0,3245 gram of sodium acetate.Or a mixture of phenylhydrazine (1 c.c.) glacial acetic acid (2 c.c.) and water (10 c.c.) may be employed. After two hours or if the quantity of hydrazine is small after being left overnight the mixture is examined micro- scopically. F u l l details respecting the mode of applying the method are given and the behaviour of dextrose towards phenylhydrazine is also described. A number of experiments were made in connection with the lead acetate test. Mannose was found in the trunk-wood of sugar-maple trees but not in the wood of the grey birch poplar and willow. It occurs i n orange- peel (not in the seeds) in the artichoke roots in horse chesnuts and in the storage-roots of chicory dandelion and asparagus. The seeds of white pine and Norway spruce contain only a small amount of mannose whilst the wood of these and other pines contains it in con- siderable quantity.N. H. J. M. Analyses of Honey. By R. RACINE (Zed. ofentl. Chern. 1902 8 281-286).-Thirty-nine analyses are given of samples of pure and adulterated honey. Each analysis includes an estimation of the water (dry solids) total sugars ash specific gravity and polarisation of the sample. The principal adulterants detected were invert sugar,ANALYTICAL CHEMISTRY. 705 “ starch syrup,” molasseg and water always indicate the presence of water in better to estimate the dry solids directly for this purpose.

Falsifc. 1902 15 97-100).-The starch is first washed with distilled water to remove soluble matters and is then allowed to dry at the ordinary temperature.About 2.5 grams are then well stirred in a beaker with 150-200 C.C. of water 15 C.C. of a solution of alum (of such strength that each C.C. corre- sponds with 0.01 gram of aluminium hydroxide) are added and the mixture is precipitated with a slight excess of ammonia. The precipi- tate is collected on a tared filter thoroughly washed with the least possible quantity of water dried at looo and weighed. From the weight found the known quantity of aluminium hydroxide present is subtracted the result being starch. In the case of flour about 3 grams are placed in a small china basin and formed into a dough by adding a small quantity of water.The lump of dough is then kneaded under a jet of water until all starch has been removed The washings containing the starch in suspension are precipitated as above. w. P. s. The Composition and Analysis of Starch Syrups. By MAX HONIG (Zeit. Nahr. Genumm. 1902 5 641-653).-Commercial starch syrups contain besides dextrose two groups of dextrins. One group consists of erythrodextrin and achroodextrin ; these may be separated from starch syrup by precipitation with 87 per cent. alcohol (Konig’s method) and then from each other by fractionation from alcohol. The author separates them from the syrup by treating 100 C.C. of a solution containing not more than 1 per cent of dextrose in a 200 C.C. graduated flask with 50 C.C. of saturated barium hydrox- ide solution. Sufficient 95 per cent.alcoholis then added to make the volume up to 200 C.C. after cooling and shaking. The dextrins are precipitated whilst the dextrose remains entirely soluble. The other group consists of dextrins which are soluble in alcohol as are also the barium salts which remain in solution with the dextrose in the above described method of separation. They may be separated from dextrose by fermentation of the filtrate. A scheme for the analysis of starch sypups is also given and includes the estimation of (1) The dry soiids by evaporating 50 C.C. of a solution containing 10 grams of syrup in 500 C.C. of water and drying the residue under reducsd pressure for 4 hours at looo; (2) ash; (3) the cupric reducing power of a 10 per cent. solution of the syrup by Soxhlet’s method ; (4) the cupric reducing power of t.he solution after the separation of the dextrins; (5) the cupric reducing power of an inverted portion of the original solution ; and (6) the cupric reducing power of the inverted filtrate By A.PFAFF (Chem. Zeit. 1902 26 701).-The solution of formaldehyde (containing about 0.4 per from the dextrin precipitate. w. P. 8. Estimation of Formaldehyde.706 ABSTRACTS OF CHEMICAL PAPERS. cent.) is digested in a closed flask for one hour with a known volume of Eolution of hydrazine and the unabsorbed hydrazine is then titrated with N/10 sulphuric acid using methyl-orange as indicator ; 1 mol. of sulphuric acid neutralises 2 mols. of hydrazine. Two mols. of formal- dehyde absorb 1 mol. of hydrazine.The test-analyses agree very well with those obtained with Romp’s iodometric method (Abstr. 1897 ii 166). L. DE K. Detection of Hydrogen Cyanide in Presence of Thiocyanic Hydroferrocyanic and Hydroferricyanic Acids and their Salts. By LOUIS E. PREISS ( Amer. Chem. J. 1902 28 240-241)- After removal of the heavy metals and alkaline earths by boiling with sodium carbonate potassium hydroxide and aluminium filings are added to the solution which is then left until the whole of the ferri- cyanide has been reduced. The solution is now acidified with hydro- chloric acid and excess of mercuric chloride is added in order to pre- cipitate the hydroferrocyanic acid. The filtrate is made alkaline with potassium hydroxide and filtered ; the clear solution is boiled with solution of ferrous sulphate and again filtered.Hydrochloric acid and ferric chloride are added and the iron thiocyanate is decolorised by means of mercuric chloride whereby the precipitate of Prussian blue is rendered visible. E. G. Iodometry of Thiocyanic Acid. By ALFRED THIEL (Bey. 1902 35 2766-2768. Compare Rupp and Schied this vol. ii 538).- Potassium thiocyanate dissolved in a cold aqueous solution of sodium hydrogen carbonate is digested for 4 hours with excess of standard iodine solution in a loosely stoppered bottle. The mixture is then treated with excess of hydrochloric acid the cyanogen iodide formed in the first reaction being destroyed in the acid solution in ac- cordance with the following equation CNI +HI = HCN +I,. The product is now titrated with standard thiosulphate solution employing starch as indicator in the ordinary way.The amount of free iodide destroyed is a measure of the thiocyanate present KCNS++I,+ 4H,O = KI + 5HI + H,SO + HCN. G. T. M. Estimation of Uric Acid in Urine. By ADOLF JOLLES (Zeit. physiol. Chem. 1902 36 39-41).-The author states that the unsatis- factory results obtained by Matrai (this vol. ii 541) mere due to his not having followed the method as originally described. W. P. S. Estimation of Uric Acid by Jolles’s Process. By ALFRED WOGRINZ (Chem. Centr. 1902 ii 666-667 ; from Oesterr. Chem. Zeit. 5 319-320).-Jolles’s process (Abstr. 1900 ii 450) is recommended. If a somewhat exceksive amount of permanganate has been used the quantity of alkaline hypobromite should be increased by 5 or 10 C.C.L. DE K. Oxidation and Estimation of Uric Acid and Urates. By JAMES F. TOCHER (Pharm. J. 1902 [iv] 15 161-166).-When a dilute solution of uric acid is oxidised with acid permanganate carb-ANALYTICAL CHEMISTRY 707 amide and alloxan are produced. Alloxan may be readily detected by the deep rose-red coloration produced when it is warmed with dilute ammonia and which is changed to purple by sodium or potassium hydr- oxide. The variable results obtained by Hopkins’s method of estimating uric acid are mainly due to the presence of alloxan formed during the reaction ; if however the titration is carried out in a cold very dilute solution and the end reaction is taken a t the point a t which the colour persists for about 15 seconds the Hopkins factor is trust- worthy Constant results cannot be obtained by boiling the solution of uric acid with excess of alkaline permangsnate and titrating back.When uric acid is boiled for 2 minutes with solution of chromic acid it is completely converted into carbamide and carbon dioxide ; in a concentrated solution of chromic acid however a small portion of the carbamide may be converted into ammonia. The carbamide produced is estimated by means of hypobromite in a modified Doremus tube. In the analysis of urine the uric acid is precipitated as ammonium m t e and oxidised with chromic acid as described above. I n clinical work a sample of the urine may be oxidised with chromic acid and the total nitrogen estimated by the hypobromite method the nitrogen due to the carbamide being estimated in another portion from which the uric acid has been precipitated as barium urate.An appendix to the paper contains a summary of the various methods for the estimation of uric acid which have been suggested by previous workers. E. G. Estimation of the Acidity of Urine by Calcium Sucrate. By J. DE GIRARD and J. VIRES (Bull. Xoc. Chim. 1902 [iii] 27 892-895. Compare Joulie Abstr. 1898 ii 315).-The author finds t h a t when calcium sucrate is added to a solution of an acid phosphate of an alkali metal dicalcium phosphate and an alkali phosphate are formed whilst a portion of the original acid phosphate remains in t h e solution which also has an acid reaction. F o r this reason calcium sucrate cannot be employed to estimate the acidity of urine.A. F. The Occurrence of Salicylic Acid in Natural Wines. By KARL WINDISCH (Zed. Nuhr. Genusmn. 1902 5 653-662).-The .author was unable to detect the presence of salicylic acid in grapes of the 1901 vintage in Germany and comes t o the conclusion that it may be present in one year and not in another. That it is sometimes present is proved by the investigations of others (Ferreira da Silva and Mastbaum). The amount which has been found is extremely small and is not detected by the ordinary method of testing wine for added salicylic acid. w. P. s. mpid Method for the Analysis of Soaps. By FERNAND TELLE (J. Pharrn. Chim. 1902 [vi] 16,121-125).-The soap (2grams) is dissolved in hot water 10 C.C. of N-hydrochloric acid are added the fatty acids extracted with ether and weighed.In the aqueous solution the excess of hydrochloric acid is titrated andfrom the result the total alkali deduced. The uncombined alkali hydroxide or carbon-708 ABSTRACTS OF CHEMICAL PAPERS. ate in the soap is estimated by a modification of Divine’s method (A bstr. 1900 ii 769)’ in which approximately A7/10 oleic acid is Used in place of stearic acid. H. R. LE S. Estimation of Fat in Milk by means of the Refractomefer. By SIGMUND HALS and HARALD GREGU (Milch Zeit. 1902 31 433-436).-Wollny’s refractometric method was compared with the Adams process for the estimation of fat in milk. The results of numerous analyses by both methods show that the percentages of fat found by the refractometer in all cases agree very accurately with the amount as determined by the Adams process.Milk with and with- out perservatives which had been kept for from 3 to 5 weeks gave slightly lower results by the Wollny method the difference averaging - 0.06 per cent. Wollny’s method as used in these experiments was a8 follows 20 C.C. of milk were shaken with 1 drop of copper chloride solution (238 grams per litre) and 3 drops of glacial acetic acid for 16 minutes at a temperature of 17.5O. One C.C. of a solution containing 250 grams of potassium hydroxide 500 C.C. of water 250 C.C. of glycerol and 100 grams of copper carbonate was added and then 4 C.C. of ether previously saturated with water a t 1’7~5~. The mixture was shaken for 15 minutes and subjected to centrifugal action the refraction of the ethereal fat solution being then determined. Naumann’s modification of this method was not found to give accurate results in the case of fresh skimmed milb-,.where the amount of fat is low but with sour milk it worked more satisfactorily.W. P. S. Analysis of Butter Fat and the Relation between the various Constants of the same By PAUL BEHREND and H. WOLFS (Zeit. Nahr. Genusma. 1902 5 689-71 9).-The butters ex- amined were obtained from the milk of separate cows each butter fat being analysed separately. From the averages of the results obtained i t is seen that to a certain exftent there is a relation between t h e various analytical values. The Reichert-Meissl numbers of the fats decreased as the melting point rose and the latter approximately in- creased in proportion with the amount of insoluble fatty acids. The Reichert-Meissl numbers also diminished as the refractometer values increased. Little relation exists between the refractometer value and the melting point. The iodine values increased with the refractometer readings the Kottstorfer values at the same time showing a decrease.The Kottstorfer and Reichert-Meissl numbers increased as the iodine values and insoluble acids decreased. w. P. s. The Unsaponifiable Substances in Butter Fat. By ARTHUR KIRSTEN (Zeit. fluhr. Genu88m. 1902 5 833-856).-The unsaponifiable matter found in butter fats consists principally of cholesterol with small quantities of lecithin and yellow colouring substances. The cholesterol is best separated and estimated by Bomer’s method; 10 grams of the butter are saponified with an alcoholic solution of potassium hydroxide and the dilute soap solution thoroughly extracted with ether.After distilling off the latter the residue is again treated with potassium hydroxide solution and extracted with ether. TheANALYTICAL CHEMISTRY. 709 ethereal solution is shaken with 5 per cent potassium hydroxide solution the latter being afterwards extracted with ether and the united extracts washed with water and filtered. The final residue from the ether is dried at 100' and.weighed the weight giving the amount of '' crude " cholesterol in the fat. A'number of estimations of the latter are given the results showing that the quantity varies slightly according to the period of lactation. At the commencement of lactation the average amount of " crude " cholesterol is 0.375 per cent. rising a t the end to 0.50 per cent.w. P. s. [Detection of Margarine.] By FRANZ UTZ (Chem. Zeit. 1902,26 730-731).-A series of experiments which proves that under certain as yet unknown conditions the active principle of sesame oil may pass into the .milk and consequently into the butter prepared therefrom and then cause the Baudouin or Soltsien reactions which have lately been recommended for the safe detection of margarine in butter. It must be remembered that in some countries margarine always contains an admixture of sesame oil as prescribed by law. The quantity introduced seems however to be so trifling that the Eeichert-Meissl number and the refraction of the butter are not sensibly affected when the cows have been partially fed on sesame cakes.L. DE I(. Refractive Indices of Salad Oils-Correction for Tempera- ture. By L. M. TOLMAN and L. s. MUNSON (S. Amer. Chern. Soc. 1902 24 754-758).-Using a Zeiss butyro-refractometer it was found that the correction for change in the refractive index for lo amounted to 0.000365 for ordinary fats and oils (cotton olive poppy-seed sunflower rape mustard black mustard lard pea-nut and sesame). The change in the refractive index for variation of tempera- fure being more constant than the change in scale divisions it is better to calculate the scale reading into the refractive index make the above correction and recalculate into scale divisions. For cor- rections of a few degrees the formula R = R - X(T- T) may be employed R= reading corrected to F R'= reading at P F= desired temperature 2"= temperature a t which reading was made and X= change in scale division caused by change of temperature for lo.For butters which read from 40-50' on the scale K=O55; for oils reading from 60-70° it is 0.58; and from 70-80' it is 0.62. w P. 8. The Influence of the Growth of Mould on the Chemical Com- position of Oleomargarine and Butter. By CHARLES A. CRAMPTON (J. Amer. Chem. Soc. 1902 24 711-719).-About 50 samples of margarine which had been kept in glass-stoppered bottles for 2 years were re-examined at the end of this time. Many of the samples had become permeated with a growth of dark green mould a (probably undescribed) species of Coniothecium. The refractive indices of the samples varied to a considerable extent being particularly low in those showing the strongest growth of mould.The mouldy samples also gave much lower Reichert-Meissl figures as compared with a'710 ABSTRACTS OF CHEMICAL PAPERS. sample of the original fat which had not become mouldy and the specific gravities were unusually low. An analysis of a sample of mouldy butter confirmed the statements- of Hanui and Stocky that the growth of moulds produces a decrease in the Reichert-Meissl figure (Abstr. 1900 ii 772). The conclusions are that in the case of edible fats where the presence of nitrogenous and other non-fatty matters afford a medium for the growth the greater part of the changes included under the general term '' rancidity " is due to the action of micro-organisms or to the enzymes resulting from their development.The results obtained in the experiments with the oleomargarines are explained by the author h i s explanations agreeing with those of Konig Spieckermann and Bremer Microchemical Analysis of Alkaloids. By M. EMM. Pozer- ESCOT (Ann. Chim. anaZ. 1902 7 337-338. Compare Abstr. 1901 ii 485).-A reply to Surre (this vol. ii 543) who has applied the New Reactions for Quinine and Quinidine. By EDUARD HIRSCHSOHN (Chm. Centr. 1902 ii 540; from Pharm. Centr. EaUe 43 367-368).-Neutral solutions of quinine and quinidine hydro- chloride or sulphate turn a raspberry-red colour when boiled with a drop of a solution containing 2 per cent. of hydrogen peroxide and 1Q per cent. of copper sulphate and thus behave like a solution of aloin. The colour gradually changes t o violet-blue and finally to green.In similar circumstances thalline mlphate or tartrate give an onion- red kairine an intensive blue and asparagine a light blue colour. All the other alkaloids glucosides and bitter substances which have been investigated by the author are not coloured a t all or only turn psle yellow or brownish. Free acids and alcohol interfere with the re- action. Separation of Brucine from Strychnine. By ALBERT B. LYONS (Pharm. Rev. 1902 20 253-255).-The process is intended for the assay of nux vomica extract. The mixed strychnine and brucine ob- tained in the ordinary way is treated with dilute (10 per cent,) sul- phuric acid U.S.P. using 1 C.C. of acid for every 0.015 gram of the alkaloidal mixture. It was found that in these circumstances 1 C.C.of acid dissolves only 0.00175 gram of strychnine so that the bulk of this remains as insoluble sulphate whilst the brucine is practically all dissolved. After collecting the insoluble matter on a very small filter and wash- ing with a few drops of acid the strychnine may be recovered by shaking the sulphate with ammonia and chloroform; the latter on evaporation yields the fairly pure alkaloid. If it is desired to avoid making a correction for the slight solubility of strychnine an acid satur- ated with the alkaloid may be used. This may be prepared by adding t o 100 C.C. of a 10 per cent. sulphuric acid 0.275 gram of brucine and 0.225 gram of strychnine and filtering after an hour. The addition of brucine is necessary as it increases the solubility of the strychnine (Abstr.1901 ii 676). w. P. s. process previously used by the author. L. DE K.

Compare Abstr. 1901 ii 631).-Four grams of the finely powdered sample are triturated in a mortar with 2 grams of freshly burnt calcium oxide and 10 C.C. of water; another 19 C.C. of water are added and the whole is frequently stirred for half an hour. Fifteen C.C. of the filtrate are then placed in a 60 C.C. bottle 4 C.C. OF alcohol and 10 C.C. of ether are added and the whole is well shaken. Half a gram of ammonium chloride is next added and after shaking for half an hour the whole is set aside in a cold place for 12 hours.The super- natant ether is then poured off into a funnel closed with a plug of absorbent cotton and the bottle is rinsed with another 10 C.C. of ether. The contents of the bottle are poured into the funnel and both crystals in the funnel and bottle are washed with water saturated with morphine until the washings are colourless. The funnel is now placed over the bottle the cotton lifted with a glass rod drawn out to a curved point and the crystals are rinsed into the bottle with 12 C.C. of N/10 sulphuric acid; the cotton is then also put into the bottle which is then corked and well shaken. After rinsing both cork and funnel with water the excess of acid is neutralised by N/40 potass- ium hydroxide. The number of C.C. of N/10 acid consumed multi- plied by 1.5038 gives the percentage of morphine in the sample; to this must be added an extra 1.12 per cent to compensate for morphine remaining in solution.L. DE E. Evaluation of Ipecacuanha Root. By GUSTAV FRERICHS and N. DE FUENTES TAPIS (Arch. Pharm. 1902 240 390-423).-The authors have analysed the hydrochlorides of emetine and cephaeline and found the same composition as Paul and Cownley (Abstr. 1896 i 192 ; Amer. J. Pharm. 1901 73 57 107) ; they incline towards the formuls adopted by the latter. Cephaeline melts at 119' when all the solvent has been driven off from it. An historical account is given of the various methods proposed for the evaluation of ipecacuanha root and the methods are examined critically. Preference is given to the following ones which are slight modifications of those of Keller (Abstr.1893 ii 39'7; 1894 ii 263). It is thought that a determination of the amount of emetine and cephaeline together is sufficient as the amount of psychotrine (Paul and Cownley Amer. J. Pharrn. 1901 Zoc. cit.) is relatively very small; moreover the colour caused by the presence of psychotrine renders impossible a titration of the alkaloids with iodeosin as indica- tor. The weights of the two alkaloids which combine with 1HC1 being respectively 248 and 234 1 C.C. of 0.1N hydrochloric acid may be taken without serious error as corresponding with 0.0241 gram of alkaloid. Psychotrine is not dissolved by ether and even when ether- chloroform is used it is not dissolved when sodium carbonate has been employed to set free the alkaloids.VoZumetric.-Shake 6 grams of the powdered root with 60 grams of ether add 5 C.C. of ammonia solution (10 per cent. I) or 5 C.C. of sodium carbonate solution (1 3) and shake at intervals during an hour. Add 10 C.C. of water shake filter off 50 grams of the ether concentrate it to half its bulk and shake it with 10 C.C. of 0*1N hydrochloric acid. Filter712 ABSTRACTS OF CHEMICAL PAPERS. the acid shake the ether twice with 10 C.C. of water running this wash- water through the same filter into the acid extract dilute to about 100 c.c. add so much ether that a layer 1 cm. or so deep remains on the surface of the liquid after shaking then add 5 drops of iodeosin solution (1 250). and titrate with O01N potassium hydroxide. Multiply the net number of C.C.neutralised by the alkaloid by 0.482 ; the result is the percentage of alkaloid in the root. Gmwimetric.-This method is to be preferred when an evalu- ation of the drug has to be performed only occasionally. The 50 grams of ethereal solution mentioned above are shaken with 5 C.C. of dilute hydrochloric acid and 10 C.C. of water and the aqueous extract is removed to another separating funnel ; the ether is then extracted twice in succession with 10 C.C. of water and the extracts are removed to the same funnel. To the acid liquid 5 C.C. of ammonia solution are added and the mixture is shaken with 50 grams of ether ; 40 grams of the ethereal extract are evaporated in a tared flask and the residue dried at 100° and weighed ; 25 times this weight gives the percentage of emetine and cephaeline together in the sample. It is possible to check the result by dissolving the residue in 5 C.C. of 0*1N hydrochloric acid adding water ether and iodeosin and titrating back with 0.1N potassium hydroxide; the end-point is obscured however by a dis- coloration resulting from the slight decomposition which the alkaloids undergo when dried. A certain aiwurance against adulteration may be obtained by testing qualitatively for cephaeline ; dissolve the residue in Frohde’s reagent and add a particle of sodium chloride when dark blue coloration will appear if cephaeline is present. A determination of the total amount of emetine and cephaeline suffices for most practical purposes. If the separate amounts are required the determination must be repeated the cephaeline being removed from the ethereal solution by shaking it three times with about 10 C.C. of aqueous sodium hydroxide and the residual emetine determined ; the oephaeline is determined by difference. To estimate the psychotrine make a third determination extracting the alkaloids with ether-chloroform and subtracting from the total weight of alkaloids so found the weights of emetine and cephaeline.

701 Organic Chemistry. Direct Hydrogenation of Acetylene Hydrocarbons by Contact Action, By PAUL SABATIER and JEAN B. SENDERENS (Compt. Tend., 1902, 135, 87-89).-Heptylidene, in presence of excess of hydrogen and in contact with reduced nickel a t about 170°, is con- verted into normal heptane together with small quantities of higher hydrocarbons of the same series. Reduced copper above 200" produces a-heptylene, diheptylene, and triheptylene as well as normal heptane. Phenylacetylene, in presence of excess of hydrogen, is converted by nickel a t about 180' into ethylcyclohexane boiling a t 130" together with a small quantity of methylcyclohexane. Copper at 190" to 250' converts the phenylacetylene mainly into metastyrene, ethyl benzene, and diphenylbutane, the yield of the last reaching as much as 50 per cent.(compare this vol., i, 525). Reduction of Nitro-compounds by Direct Hydrogenation in Contact with Finely Divided Metals. By PAUL SABATIER and JEAN B. SENDERENS (Compt. rend., 1902, 135, 225-227. Compare Abstr., 1901, i, 459).-~-Nitronaphthalene with an excess of hydrogen, when in contact with finely divided copper a t 330-350°, is reduced to a-naphthylamine. The reduction can also be carried out with a mix- ture of carbon monoxide and hydrogen. With nickel at the same temperature, the reduction proceeds further, so that some tetrahydro- naphthalene is produced. I n presence of reduced nickel a t 150-180', nitromethane is com- pletely reduced to methylamine, but a t 320" reduction takes place to methane and ammonia. Nitromethane is not reduced by hydrogen in presence of copper below 300' ; above this temperature, reacbion takes place, part of the nitromethane suffers reduction, and a compoiind of nitromethane with methylamine results, the prodtlct being identical with a solution of nitromethane in aqueous methylamine.With nickel at 200°, nitroethane is easily reduced to ethylamine. The reaction with copper is analogous to that found for nitromethane. Action of Hydrazine Hydrate on the Aldol from isoButyr- aldehyde and Formaldehyde.

When distilled or when exposed to moist air containing acid vapours, the aldazine is decomposed, giving an odour of amines and of ammonia. When heated with dilute sulphuric acid a t 90°, boiled with dilute aqueous or alcoholic hydrochloric acid, or when treated with hydrogen chloride in benzene solution, the aldazine is hydrolysed to hydrazine and the aldol.When heated with maleic acid a t 130°, the aldazine forms a yellow, crystalline derivative which melts at 121', decomposes at 150°, and is probably a pyrazoline compound. Sulphur and Nitrogen Derivatives of Carbon Disulphide. V. Dithiocarbamic Esters derived from Secondary Aromatic Amines. VI. Aromatic Xrninodithiocarbonic Esters. By MARCEL DELBPINE (Bull. Xoc. Chirn., 1902, [iii], 27, SO7-812. Com- pare Abstr., 1901, i, 518; this vol., i, 199, 353, 595, 597).-By the action of carbon disulphide on methylaniline in presence of an alcoholic solution of ammonia, the author obtained ammonium methylphenyl- dithiocccrbarnate, NMePh*CS*SNH,, in the form of -yellowish, lozenge- shaped plates, sparingly soluble in cold water or alcohol, and insoluble in ether ; it is only slightly stable in air.Ammoniumphenylethyldithio- car6ccmate, obtained in a similar manner, is closely analogous in its properties t o the preceding compound. Dithiocarbamic esters can be readily prepared by acting with an alkyl haloid on the preceding salts suspended in cold alcohol, By acting on a dithiocarbamic ester derived from aniline in cold ethereal solution with methyl iodide, the hydriodide of an iminodithio- carbonic ester is obtained which decomposes in aqueous solution into the ester and hydriodic acid. On employing an alcoholic solution and heating at 50-70°, the ester is also formed, but the reaction is more complicated.Quantitative yields are obtained by acting with an alkyl iodide on dithiocarbamates dissolved in alcoholic solutions of potassium hydroxide. Methyl phenyliminodithiocarbonate, NPh: C( SMe),, boils at 3Oo0, solidifies on cooling, and crystallises from alcohol in elongated prisms which melt at 36'. The hydriodide melts between 110' and 120' and froths a t aboixt 130'. The picrate is viscous and is decomposed by water. MethyZ p-tolyliminodithiocabonctte, C,H,Me*N:C(SMe),, boils a t 315'. Sulphur and Nitrogen Derivatives of Carbon Disulphide. VII. Dithiocarbamic Esters derived from Primary Amines. By MARCEL DEL&PINE (Bull. Xoc. Chim., 1902, [iii], 27, 812-818. Compare preceding abstract).-These are best prepared by acting on the sulphocarbonic derivatives of primary amines with 1 mol.of an alkyl haloid. I n this way, the author has prepared methyl methyldithio- carbamate, NHISlle*CS*SMe, a thick, heavy, refractive liquid which crystallises in methyl chloride ; ethyl methyldithiocarbamate, an oily liquid ; 6enxyZ methyldithiocarbamate, which crystallisee in small plates melting a t 49.5' ; and benzyl phenyldithiocarbamate, On being heated, these compounds all decompose into thiocarbimide and mercaptan. Wh'en heated with ammonia or with amines, they also undergo decomposition with formation of substituted thiocarbamides G. Y. A. F.ORGTANlC CHEMISTRY. 703 and mercaptan, a reaction which constitutes a new method of synthesis of mono-, di-, s-, and tri-substituted thiocarbamides.The dithiocarbamic esters derived from primary amines also combine with a second mol. of an alkyl haloid, yielding symmetrical or mixed iminodithiocarbonic esters. When subjected to the action of ferric chloride, those dithio- carbamates in which a fatty radicle is attached to nitrogen are un- attacked, whilst those in which an aromatic radicle is attached to nitrogen give rise to isothiuram disdphides ; the compound NPh:C(SMe)*S~S(SMe)*C:NPh forms colourless needles melting at 123O, and the compound forms colourless needles melting a t 158'. To explain the difference in the behaviour of the primary dithio- carbamates, the author, as also for other reasons, considers that the two classes of compounds differ in constitution, those derived from fatty amines having their hydrogen attached to nitrogen, whereas in the compounds derived from aromatic amines, the hydrogen is attached to sulphur.A. F. Action of Organic Acids on Metallic Antimony. I. By B. MORITZ and C. SCHNEIDER (Zed. physikcd. Chenz., 1902, 41, 129-138).- When powdered antimony is shaken with solutions of certain organic acids in the presence of air, the antimony is attacked. The presence of air is essential, and the diminution of the air volume accompanying the action corresponds with the quantity of oxygen it contains and with the quantity of antimony which has passed into solution. Only acids containing the hydroxyl as well as the carboxyl group have the power of attacking antimony under the above conditions; further, it appears that the hydroxyl and carboxyl groups must be attached to the same carbon atom ; thus, whilst a-hydroxybutyric acid acts readily on the metal, the /?-acid is almost without effect.I n all cases, the quantity of antimony passing into solution is greatest when the acid has been partly neutralised with soda, and the mixture therefore contains the acid salt. Of dibasic acids, oxalic, malic, tartatic, and citric acids readily attack antimony as above described. Malonic and succinic acids, on the other hand, are without effect, and the same holds for phenol and benzoic and salicylic acids. Solutions of gdlic and tannic acids produce in a few minutes precipitates containing antimony. I n the course of their work, the authors have isolated a crystalline compound of lactic acid with sodium and antimony, having the empirical formula S bONa,( C,H,O,),. By MARCEL GUERBET (BUZZ.Xoc. Chim., 1902, [iii], 27, 803-S07),-The author has prepared mercurous lactate by dissolving freshly precipitated mercurous oxide in dilute lactic acid, previously heated with water in order to destroy the anhydride, &c., which it contains. The solution thus obtained is allowed to evap- orate in a desiccator over sulphurio acid, when mercurous lactate separates out in short, white, prismatic needles having the composition (C,H,O,),Hg,,H,O. It does not dissolve entirely in water, hydrolysis occurring with formation of a basic lactate, which then decomposes into mercuric lactate and mercury.

It is very soluble in water ; on boiling this solution, the mercuric salt passes into mercurous, and there are formed at the same time carbon dioxide, aldehyde, and lactic acid. The substances described as lactates of mercury by Engelhard and Maddrel and by Briining are found by the author t o be mixtures. A. F. Action of Nitrous Acid on a-Substituted /!-Ketonic Esters. Synthesis of the Homologues of Pyruvic Acid. Ey LOUIS BOUVEAULT and RENE LOCQUIN (Compt. rend., 1902,135, 179-182).- By the action of nitrous acid on a-substituted acetoacetates, two pro- ducts are formed according to the equations : (I) COMe*CHR*CO,Et + HNO, = Me*CO,H + NOH:CR*CO,Et and (11) COMe*CHR*CO,Et + HNO, = EtOH + COMe*CR:NOH + CO,.In acid solution, the former reaction takes place exclusively. The same oximoglyoxylic ester is obtained in starting with ethyl ethylhexoylacetate or ethyl ethyl- acetoacetate, namely, NOH:CEt*CO,Et. This oxime of ethyl methyl- pyiwuate boils at 125-130' under 10 mm. pressure; it crystallises in white needles which are soluble in light petroleum and melt at 58'. From ethyl isoamylacetylacetate, the authors have prepared the oxime of ethyl iso6utylpyruwute, CHMe,*[CH,],*C(:NOH)*CO,Et, as a n oil which boils at 114' under 12 mm. pressure and has a sp.gr. 0,9114 at 4'/0'. The corresponding acid, obtained by saponification, melts at 160' with decomposition. Ethyl isobutylpyruvate boils at 105' under '18 mm. pressure.

The corresponding acid melts at 88-89'. J. McC. Preparation of a-Derivatives of P-Ketonic Esters. By R E N ~ LOCQUIN (Compt. rend., 1902, 135, 108--llO).--When the C-esters of t h e acylacetoacetates (Abstr., 1901, i, 311) are treated with an alkyl iodide and a sodium alkyloxide in presence of a n excess of alcohol, a good yield is obtained in accordance with the equation CHAc(COR).CO,Et + NaOEt + R'I = Me*CO,Et + N a I + R*CO*CHR'*CO,Et, whilst if an alkyl bromide is used the reaction is more complicated and proceeds partly in accordance with the equation CHAc(COR)*CO,Et + NaOEt + R'Br = R*CO,Et + NaBr + UHAcR'*CO,Et.Ethyl ethylhexoyhcetate, boiling at 128-129' under 13 mm. pressure, and of sp. gr. 0.9325 at 4O/O", is obtained in this way from ethyl C-hexoylacetoacetate, which boils at 136' under 10 mm. pressure and has a sp. gr. 1.032 at 0'.

I t s pyraz- olone is liquid and boils and partially decomposes at about 270' under 30 mm. pressure. Di-p-phenetidide of Agaric Acid. J. D. RIEDEL (D.R.-P. 130073).-The di-p-phenetidide of agaric acid, produced by heating this acid with 2.5 mols. of p-phene$idine a t 140--160' either under pres- sure or in a current of indifferent gas, crystallises from glacial acetic acid, alcohol, or a mixture of benzene and petroleum in small needles melting a t 150-152'; it is insoluble in water or dilute acid or alkaline solutions.The compound is very soluble in cold chloroform, but dis- solves less readily in other organic solvents of low boiling point.

By LOUIS BOUVEAULT and R E N ~ LOCQUIN (Compt. rend., 1902, 135, 295-297).-When ethyl isoamylacetoacetate is treated successively with an alkali hydroxide, sodium nitrite, and an acid, it yields, in almost calculated quantity, nitrosoisoumylacetorte, C1HMe,*CH2*CH,*CAc:N OH, which melts at 32-33', boils at 128' under IS mm. pressure and with hydroxylamine yields a dioxime melting a t 181'. With the higher homologues of the ester, however, the reaction does not suc- ceed, because the action of the alkali hydroxide yields a very unstabre salt, which decomposes in accordance with the equation R*CO*CHR'*CO,Na + NaOH = R*CO*CH,R' + Na,CO,.If, however, the ester is mixed with the calculated quantity of sodium ethoxidc in presence of absolute alcohol and dry ethyl nitrite is passed into the solution, the reaction proceeds as in an acid solution (this vol., i, 704), CHAc(C,H,,)~CO,Et + EtNO, = Ne*CO,Et + NOH:C(C,H,,j=CO,Et. If amyl nitrite is used instead of ethyl nitrite, mixed esters are obtained by partial substitution of amyl for ethyl. The results indicate that if the reaction of nitrous acid with the a-substituted-P-ketonic esters takes place under such conditions that the alkyl group is not hydrolysed a t all or is hydrolysed in presence of an acid, the products are an acid and the oxime of a substituted glyaxylic ester, whilst if during the reaction the alkyl group is hydro- lysed so as to form a salt, R.CO*CHR*CO,M, the products are car- bon dioxide and the monoxime of an a-diketone.Dimethylene Tartrate.

G. T. M.708 ABSTRACTS OF CHEMICAL PAPERS. Coloured Organic Ferric Compounds. By ARTHUR HANTZSCH and CECIL H. DESCH (AnnaEen, 1902, 323, 1 -31).-Determinations of the electrical conductivity of aqueous solutions of ferric acetyl- acetone indicate that the substance is practically a non-electrolyte, the values obtained being E~~~ = 0.72, and qo2? = 1-68.The compound is very slowly decomposed by hydrochloric acid, even when this reagent is in excess, and the change has been studied quantitatively by deter- mining the electrical conductivities of solutions of the substance with one, two, or three molecular proportions of the acid. The decomposition of the salt by hydrogen chloride in anhydrous solvents is instantaneous and complete, but when the reagent is gradu- ally added the change is seen to occur in three stages, the light red solution becoming deep red, then reddish-violet, and finally assuming the pale yellow colour of ferric chloride.The colour changes correspond with the gradual transformation of Fe(C,H?O,), into Fe(C,H70,),C1 and Fe(C,H70,)C11,. Aluminium acetylacetone is as poor a conductor of electricity as its ferric analogue, and is even less readily attacked by hydrochloric acid. Ethyl ferrihenzo ylacetate, Fe( C,,H,,Cl,),, obtained as an oily residue by extracting with ether a concentrated solution of ferric chloride, sodium acetate, and ethyl benzoylacetate in dilute alcohol, slowly becomes solid and separates from its alcoholic solution in deep red crystals melting a t 12s'. Ethyl ferrioxaloacetate, Fe(C,H,,O,),, prepared in a similar manner, separates as a lustrous, dark red, hygroscopic powder on diluting its alcoholic solution with water.Although ferric chloride and ethyl acetoacetate develop an intense coloration, the amount of ethyl ferriacetoacetate actually produced in aqueous solutions is but very small ; the reaction takes place, however, t o a greater extent when the reagents are dissolved in alcohol. Ferrisalicylic acid, OH*Fe( O*C,H,*CO,H),, produced by shaking an ethereal solution of salicylic acid with a concentrated aqueous solution of ferric chloride and sodium acetate, crystallises from the ethereal extract in red prisms which contain 1 mol. of ether. The compound, when freed from ether, has a purple colour and dissolves in water to a reddish-violet solution ; it behaves as an acid salt, dissolving in solu- tions of the alkali hydroxides without decomposition.o-Methoxybenzoic acid does not react with ferric chloride ; methyl salicylate and salicylaldehyde develop colorations with ferric chloride, but the products could not be isolated. Electrolytic determinations show that the amount of coloured salt formed from phenol and ferric chloride is very small ; this is also true of resorcinol, but its isomerides show more tendency to enter into reaction, the amount of double decom- position being greatest in the case of catechol. Pyrogallol and p-aminophenol, when treated with ferric acetate, yield violet-black substances which are insoluble in water or the organic solvents, but dissolve in hydrochloric acid to a yellow solution. Ethyl dicarboxyglutaconate and excess of ferric chloride in dilute alcoholic solution develop a blue coloration, but the actual amount of double decomposition is very small.Ferric cccetylhydroxamate, Fe(C,H,0,N)3, separates in deep red prismsORGANIC CHEMISTRY. 709 from an alcoholic solution of acetylhydroxamic acid and ferric ethox- ide ; it readily dissolves in water t o a bluish-red solution ; its equivalent conductivities at 25’ are P ~ ~ ~ . ~ = ‘7.5, and E ~ ~ ~ . ~ = 8.4 respectively. The salt is accordingly a ‘‘ half-electrolyte ” ; i t s degree of ionisation, although far less than that of a normal salt, is greatly in excess of that of ferric acetylacetone. The aqueous solution of the salt givesno precipitate with potassium ferrocyanide, but ferric hydroxide is slowly deposited on adding strong ammonia solution ; hydrochloric acid develops an intense violet coloration, which disappears on adding excess of the reagent.- o*?:NoH produced O-CNOH ’ Ferric oxalodihyhoxarnate, OH*Fe< the interaction of oxalodihydroxamic acid and ferric acetate, separates as a deep violet precipitate, dissolving in excess of ferric chloride solution t o a violet solution. The ferric salt is insoluble in water, alcohol, or ether, explodes on heating, and dissolves in solutions of the alkali hydroxides without decomposition. Ferric salicylh ydroxamccte, C 6 H 4 < c E > F e OH, resembles the preceding salt and dissolves without decomposition in solutions of the alkali hydroxides. Lanthanum acetylacetone, La(C5K70J3, is prepared by dissolving freshly precipitated lanthanum oxide in a dilute alcoholic solution of acetylacetone ; the reaction is accompanied by development of heat, and the salt crystallises, on cooling, in white needles.In solution, the sparingly soluble lanthanum salt is more highly ionised than its ferric and aluminium analogues; it is more rapidly attacked by hydrochloric acid than these substances. Acetylacetone and cntechol show a slight tendency to interact with boric acid. Solutions of colloidal ferric hydroxychloride, which have a marked acid reaction and a noteworthy electrical conductivity, contain their chlorine in a non-ionised condition, so that it is not precipitated as silver chloride until after acidifying. It must therefore be supposed that this chlorine exists in these solutions in the form of a complex chloroferric acid. Chlorine exists in a similar condition in the coagula obtained by carefully adding ammonia to aqueous solutions of alumin- ium chloride until the turbidity produced remains undissolved.G. T.

For example, diethyl benzylidene- bisacetoacetate, a condensation product from benzaldehyde and ethyl acetoacetate, gives the reactions of diethyl 3-methyl-5-phenyl- cyclohexan-3-01-1-one-4 : 6-dicarboxylate, the transformation being due t o an intramolecular aldol condensation, CHPh(CHAc*C02Et), - CHPh<~~[~$~))”(oH)>CH co 2’ In some cases, this change is complete, in others, the two isomerides710 ABSTBACTS OF CHEMICAL PAPERS, exist together in a condition of equilibrium.Evidence of the inverse transformation is furcished by Knoevenagel’s researches (Abstr., 1899, i, 214). The formation of the cyclic isomeride is brought about by the action of piperidine, sodium ethoxide, or other compounds of a similar nature. The 8-diketones, which have undergone complete rearrangement, are tabulated and their appropriate designations as cyclic compounds are indicated. The nature of the change involved in this rearrangement is indicated by the following diagram, C H , - C O * ~ ~ ~ ~ C O ~ ~ ~ . . . . .+ ~ H ~ ~ c o ~ ~ ~ ~ ~ . . . Diet hyl met h ylenebisace t oacet ate, when treated with hydrazine hydrate in alcoholic solution, yields 41nethylenebia-3-methyl-5-pyrazolonne, CH,( CHcb%:>N) , a substance separating in rhombic crystals and decomposing at 3 2 6 O .When left in contact with pyridine, the diketone slowly becomes transformed into diethyl 3-methylcyclohexan- 3-01-1-one-4 : 6-dicarboxylate, and the rate at which this change pro- ceeds is indicated by treating separate portions of the product at successive intervals of time with hydrazine hydrate. The yield of bispyrazolone steadily diminishes. Diethyl ethylidenebisacetoacetate is obtained as a viscid oil by mixing together ethyl acetoacetate, acetaldehyde, and a small amount of piperidine a t - 1 5 O to + 5 O ; the aliphatic nature of the product is demonstrated by theif ormation of 4-ethylidenebis-3-methyl-5-pyrazolone, which crystallises in prismatic needles and decomposes at 250’ (com- pare Rosengarten, Abstr., 1894, i, 547).The transformation product, diethyl 3 ; 5-dimethylcyclohexan-3-ol-1-one4 : 6-dica~boxyZate, melting a t 79-80”, and described by Knoevenagel as the unaltered diethyl ethylidenebisacetoacetate (Abstr., 1895, i, 50), when treated with 2 by Jrazine hydrate, yields a monopyrazolone .deri;ative, N= C--CH2*QMe*OH NH<co*bH*CHMe*CR*Co~Et’ which crystallises in needles, decomposes at 2 5 6 O , and dissolves either in acid or alkaline solutions. The cyclic ketone reacts in its enolic form when treated in ethereal solution with sodium, benzoyl chloride, and pyridine, giving rise to the OBx*f*CH,-?Me*OBz a pale yellow oil boil- CO,Et*C*CHMe *CH*CO,Et’ dibenxoyl derivative, ing at 175-185° under the atmospheric pressure and partly solidifying at the ordinary temperature.C,,H,,O,*O*CO*NHPh, of the cyclic ketone, produced by allowing its generators t o interact for 5 months a t the ordinary temperature, is a crystalline substance melt- ing a t 210’. The three isomeric PI-, &, and &-esters, obtained by condensing ethyl acetoacetate with benzaldehyde in the presence of pyridine, are now regarded as stereoisomeric diethyl 3-methyl-5-phenylcyclohexan- 3-01-1-one-4 : 6-dicarboxylates. The phenylhydrazone of the &-modifi- cation crystallises from alcohol in needles decomposing at 168-171O. The &- and &-esters both yield the same pyrazolone, C17H,,0,N,, melt- The phenylcadamide,ORBANIC CHEMISTRY. 711 ing a t 257O, which is identical with that obtained from the isomeric al-ester (compare Rabe, Abstr., 1901, i, 34).The &-ester gives rise to an isomeric pgrazolm crystallising in white needles and melting at 140". Diethyl 3-methyl-5-m-nitrophenylcyclohexan-3-01-1-one-4 : 6-dicarb- oxylate, described by Knoevenagel and Schurenberg as diethyl m-nitro- benzylidenebisacetoacetate (Abstr., 1899, i, 214), when heated with an alcoholic solution of hydrazine hydrate, yields apyrazolone, C17HI9O6N3, crystallising in prisms melting a t 260O; this forms an insoluble sul- phate and a sodium derivative. p-Nitrobenzaldehyde and ethyl acetoacetate give rise to two stereo- isomeric cyclohexanone derivatives ; the &-ester, first isolated by Knoevenagel (loc. cit.), melts a t 164O and yields a pyraxolone separating from alcohol in rhombic crystals and melting at 280'; the fl,-ester, melting at 152O, furnishes a pyraxolone crystallising in lustrous leaflets decomposing a t 260'.The ethereal alkylidenebisbenzoylacetates, unlike the corresponding condensation products from ethyl acetoacetate, are not affected by piperidine. Diethyl methylenebisbenzoylaetate (m. p. 86O), when treated with hydrazine . hydrate, furnishes a theoretical yield of 4-methylernebis-3~henyl-5-pyrazolm, which crystallises from alcohol in leaflets, decomposes a t 280°, and dissolves in dilute acid or solutions of the alkali hydroxides. 4-BenxyZidenebis-3-phnyl-B-pyraxolone, C,,H2002N4, is a very solubIe pyrazolone obtained by condensing diethyl benzylidenebisbenzoyl- acetate with hydrazine hydrate ; 4-benxytidenebis- 1-p-bromophyl- 3-phmyG5-pyrazolone, C37H260,N4Br2, is produced from the same &diketone by the action of p-bromophenylhydrazine ; it melts and decomposes at 2 9 0 O .The authors have obtained methylenebisacetylacetone only in the form of a viscid oil from which, after some months, a small quantity of a crystalline substance separates melting at 1 8 1 O (compare Scholtz, Abstr., 1898, i, 43, and Knoevenagel, i6id.) i, 449). 4-Methglenebis-3 : 5-dimethyZpyraxole, CH, ( C< zEz:$H); prepared by the action of hydrazine hydrate on the preceding &diketone, crys- tallises in rhombohedra and melts at 280O; it readily dissolves in alcohol, but is only sparingly soluble in water, The 8-diketone under- goes transformation under the influence of piperidine, but neither the cyclohexanone nor its pyrazole could be obtained in a state of purity.4 : 6-Diacetyl-5~~nyl-3-metiLylcyclohe~n-3-0l-1 -ma, ,,,,<cHAc*cMe( OH)> CHAc- 00 CH2, obtained by Knoevenagel, and also by Schiff (Abstr., 1895, i, 50, and 1900, i, 39), by condensing acetylacetone with benzaldehyde, is shown to be a cyclic compound by yielding a pyraxole, C17H2802N2, with hydrazine hydrate ; thia compound crystallised in prisms and decom- posed at 220'; the product of this reaction is a t first contaminated with an azine, which is destroyed by boiling with dilute hydrochloric acid, G, T.

Biol., 1902, 54, 352-35 3).-Increase of pressure up to 400-800 atmospheres very slightly accelerates the inversion of cane sugar by sucrase. According to Rontgen, increase of pressure has the opposite effect on inversion by acids.W. D. H. Influence of the Concentration of Cane Sugar on the Rapidity of Inversion by Sucrase. By VICTOR HENBI (Compt. rend. Xoc.

W. D. a. Action of Sodium Chloride on Inversion by Sucrase. By VICTOR HENRI (Compt. rend. Xoc. Biol., 1902, 54, 611-612).-Sodium chloride is taken as an example of a neutral salt ; a constant quantity of salt inhibits inversion to a greater extent when a strong solution of cane sugar is employed than when a weak one is used. Its inhibiting action is greater when the amount of sucrase present is small.W. D. H. Action of Neutral Salts on the Inversion of Cane Sugar by Sucrase. By VICTOR HENRI (Compt. rend. Xoc. Biol., 1902, 54, 353-354).--The results show that various neutral salts exercise an inhibiting power on the rate of inversion of cane sugar by sucrase, and that t,here is a parallelism between this action and their capacity of precipitating colloids. W. D. H. Velocity of Hydrolysis of Acetylated Monoses and Bioses. By ROBERT KREYANN (Mor~atsh., 1902, 23, 479-488. Compare this vol., i, 134).-The rate of hydrolysis, k, is determined for the penta- acetyldextrose and -galactose, tetra-acetylgalactose, tetra-acetylchloro- dextrose, and -cblorogalactose, and octo-acetyl-lactose, -maltose, and -sucrose with sodium hydroxide in 96 per cent.alcohol. The value of k for tetra-acetylgalactose remains almost constant throughout the hydrolysis, but for the other acetyl compounds k diminishes gradually, in some cases to half of its original value. This is due to a difference in the rate of hydrolysis of the different acetyl groups, the most reactive acetyl group of penta-acetylgalactose being absent in the tetra-acetyl derivative, As the value of k is smaller for the acetyl-ORGANIC CHEMISTRY. 713 dextroses than for the acetylgalactoses, the acetyl groups in the former are less reactive, this observation is made use of to explain the forma- tion of tetra-acetylnitrodextrose, and the non-formation of tetra-acetyl- nitrogalactose, from the corresponding chloro-compounds. The value of r% for octo-acetyl-lactose, which contains a dextrose and a galactose grouping, is greater than that for octo-acetylmaltose, which contains two dextrose groupings. The rate of hydrolysis of octo-acetylsucrose lies between that of octo-acetyl-lactose and that of octo-acetylmaltose, approximating more nearly to the former.Tetra-acetylchlorogalactose is obtained in large, rhombic crystals. Attempts to prepare tetra-acetyl- dextrose by the action of silver carbonate and metallic sodium on tetra- ncetylchlorodextross resulted apparently in the complete decomposition of the acetyl derivative, G. Y. Preparation and Properties of Crystallised Gentiobione. By EMILE BOURQUELOT and HENRI H~RISSEY (Compt. rend., 1902, 135, 290-292. Compare Abstr., 1901, i, 25S).-Gentiobiose has now been obtained in a crystalline form by extracting the crude mixture of sugars produced by the pnrtial hydrolysis of gentianose first with ethyl alcohol to remove laevulose and then with methyl alcohol to dissolve out the uew hexobiose. The product crystallising from the latter solvent is white, hygroscopic, and has a bitter taste; it consists of gentiobiose combined with 2 mols.of methyl alcohol and has the formula C?,H2C,,0,,,2MeOH. These crystals melt a t 85-5-86' (corr.), become solid on further heating, and fuse again a t *189--195Oto a yellow liquid ; the alcohol of crystallisation is removed only by heating at 100-1 15'. When in solution, the substance exhibits the phenomenon of multirotation, the optical activity of the dextrorotatory solution diminishing to a minimum after 19 hours, the specific rotation at this stage being + 8 * 3 3 O . Gentiobiose separates from ethyl alcohol in crystals having the composition C12H22011. I n this form it also exhibits multirotation, but the optical activity of its solution increases until a maximum is reached after 6 hours, giving [aID 9*61*.This value of the specific rotation corresponds with that obtained for the crystals separating from methyl alcohol, providing that allow- ance is made for the solvent contained in this preparation. G. T. M. Action of Enzymes on Hemicelluloses. By J. GRUSS (Chem. Cennty., 1902, i, 1277 ; from WQch. Brauerei, 19, 243-245).-Galac- tose is formed by the action of diastase powder prepared by Lintner's method on tragacanth, and under similar conditions mannan, the herni- cellulose obtained from the endosperm of date seeds, yields man- nose.By the action of the enzyme contained in the date itself, mannan is converted into mannose about twice as quickly as by a 6 per cent. solution of Lintner's diastase. Hence the hemicelluloses contained in barley are attacked by diastase, and by its prolonged action the same sugars are formed as those obtained by the action of acids.'714 ABSTRACTS OF CHEMICAL PAPERS. The original paper also contains a description of experiments in which similar results were obtained by using two diastases prepared from barley malt and oat malt by Heinzelmann's methods. E. w. w. Organic Vapour in the Air. By H. HENRIET (Compt. rend., 1902, 135, 101--103).-Air contains an organic vapour which seems to be a substituted formamide, NHRoCHO.It is slowly converted into carbon dioxide by the action of the oxygen of the air, and if the air is moist and the moisture is condensed, the resulting water reduces silver nitrate solution on boiling, converts mercuric chloride into mercurous chloride, and reduces gold chloride and alkaline potassium permangaatite. With Nessler's reagent, it gives a yellowish-green opalescence, especially if the liquid is previously heated with a small quantity of potassium hydroxide or of hydrochloric acid. The reducing power disappears if the condensed moisture is evaporated with sulphuric acid ; if it is evaporated with hydrochloric acid, the residue gives the isonitrile reaction for primary amines. Dialkylamides of isovaleric and a-Bromoisovaleric Acids.ARTHUR LIEBRECHT (D.R.-P. 129967).-isoV~ZerodimethyZamide, prepared by the action of isovaleryl chloride on dimet hylamine dissolved i n ether, boils a t 188-192O under the ordinary pressure; the corre- sponding diethylamide and the diisoccmylccinide boil a t 2 10-2 12" and 270-275O respectively under the ordinary pressure ; the latter deriv- ative is produced by heating diisoamylamine with isovaleric anhydride, isovaleroamide, or ethyl isovalerate under pressure. a-BromoisovalerodiethyZanaide results from the interaction of diethylamine and a-bromoisovaleryl bromide in ethereal solution ; it boils a t 130-135' under 20 mm. pressure. Hydroxyisopropylphosphinic Acid. By CH. MARIE (Compt. rend., 1902, 135, 106--108).-The methyl ester of hydroxyisopropyl- phosphinic acid (this vol., i, 431) melting a t 76" and t h e ethyl ester which is liquid a t the ordinary temperature are readily prepared by the action of the corresponding iodides on the silver salt.They decompose when distilled, yielding acetone and products which are still under investigation. When the esters are treated with an alkali hydroxide, decomposition takes place in two well marked stages, the first change being practically instantaneous, whilst the other necessitates the addition of a large excess of alkali and the prolonged boiling of the liquid. When treated with benzoyl chloride in presence of excess of pyridine, the acid yields 6enxoyZisopropylphosphinic acid, OBz*C,H6*P0,H,, a crystallisable compound which melts at 102' and forms a white, crystallisable silver salt, OBz*C,H6*P0,Ag,.The above facts show that the constitution of the acid is OH*UMe,*PO(OH)2.

This melts at 250' and is soluble in hot water ; alkali hydroxides added to its dilute aqueous solution separate a base which is soluble in chloroform and may be obtained pure by precipitating the solution with ether. Similar compounds may be obtained in this manner from the esters of the three aminobenzoic acids, and mention is made of the produc- tion of compounds by the action of formaldehyde on benzoylthymo1,- phenylhydrazine, and acetylphenylhydsazine. By treating resacetophenone for 2 hours with formaldehyde and hydrochloric acid and boiling the product with xylene, a n insoluble compound is obtained which, however, dissolves in chloroform and is precipitated from the solution by addition of ether.The xylene .con- tains a second product which separates as a white, crystalline sub- stance melting at 245-250' and is soluble in the alkali hydroxides.

Reduction in presence of excess of hydrochloric acid and rapid evaporation of the liquid leads to the formation of m-phenylenediamine. 4-Nitrophthalimide, formed at 170" from 4-nitrophthalic acid, crystal- lises in yellow, glistening leaflets, melts at 202O, sublimes unchanged, has solubilities similar to those of the 6-isomeride, and yields the two possible isomeric nitroanthranilic acids.5 -Nitroanthranilic acid crystallises from dilute alcohol in lemon- yellow, silky needles, melts at 2SOo, and not at 263' as stated by Hubner (Zoc. cit.), is insoluble in xylene, yields an ethyl ester which melts a t 146" (Kaiser, Abstr., 1886, 149) and an acetyl derivative melting at 214-216' ; it is converbed by diazotisation into 5-nitro- salicylic acid melting a t 288" (Hubner, Abstr., 1882, 503 ; Rupe, Abstr., 1897, i, 416), and reduced by tin and hydrochloric acid to a colourless solution which gives the p-phenylenediamine reactions either with aniline hydrochloride and potassium dichromate or with ferric chloride.4-ATitroanthraniZic mid [NH, : CO,H : NO, = 2 : 1 : 41 separates from dilute alcohol as a yellow, crystalline powder having an intensely sweet taste; it is soluble in xylene and forms an orange-red, crystalline sodium salt, easily soluble in water, and a Lqdrochloride which crys- tallises in long, delicate, glistening leaflet,s and dissociates on drying. 3 e 2720 ABSTRACTS OF CHEMICAL PAPERS. The ethyl ester, formed by the action of alcohol and hydrogen chloride, separates from dilute alcohol in clusters of yellow needles melting at 91" and when crystallised from benzene melts at 89' ; it has a burning, sweet taste, is insoluble in aqueous sodium carbonate solution, and soluble in benzene. The ace@ derivative crystallises in long, slightly yellow needles and melts at 188'.Djazotisation of the 4-acid leads t o the formation of 4-nit~oscdic?/lic acid, which crystallises in broad, short, orange-yellow needles, melts a t 235O, has a bitter taste, is easily soluble in alcohol, chloroform, or benzene, but insoluble in light petroleum, snd gives a blood red coloration with ferric chloride. This nitro-compound is reduced by tin and hydrochloric acid to 4-amino- salicylic cccicl, which forms a reddish-brown, crystalline powder, melts at 220°, is easily soluble in water or alcohol, but more sparingly so in ether, forms a hydrochloride which is easily oxidised to a dark brown mass on exposure to air, gives a n intense dark violet coloration with ferric chloride, and on diazotisation and boiling yields a solution which gives the reactions of 2 : 4-dihydroxybenzoic acid.Reduction of 4-nitroanthranilic acid by tin and hydrochloric acid leads to the formation of 2 : 4-diaminobenxoic acid, which is easily decomposed into carbon dioxide and m-phenylenediamine.

The reaction with benzaldehyde takes place without the formation of any resinous bye-products (compare Meyer, Abstr., 1882, 195). When the chlorobenzaldehydes are similarly treated, the chlorine is divided equally between the two products. o-ChZoi*ohenzyZ alcohol crystallises in white, lustrous leaflets, melts at 69-5', and is only very slightly soluble in water, but readily so in alcohol or ether. p-Chlorobenz- aldehyde is only slowly attacked by alkali ; p-chlorobenzyl alcohol melts at 7 lo.Salicylaldehyde, 23-hydroxybenzaldehyde, and vanillin do not undergo Cannizzaro's reaction with the alkali hydroxides. Anisaldehyde forms anisic acid, which melts a t 178.5'. The presence of a hydroxyl group in the ortho- or para-position renders the aldehyde incapable of reacting with alkalis. o-Nitrobenzaldehyde yields an acid which de- composes completely a t 190-ZOOo, and contains 7.5 per cent. of nitrogen. p-Nitrobenzaldehyde and its m-isorneride do not form alcohols, but by saturating the products with hydrogen chloride, amorphous substances containing 6 and 8.1 per cent. of nitrogen re- spectively are obtained. Thus the nitrobenzaldehydes do not yield the normal products, but either form acids with loss of a portion of the nitrogen o r compounds in which hydroxyl groups are present in the benzene ring.E. W.

These reactions distinguish allo- cinchonine from a- and P-zsocinchonine, these bases giving negative results in the preceding experiments. These differences may be ex- plained by assuming that allocinchonine contains a reactive hydroxyl group which is either absent in the molecules of its isomerides or marked by a different spacial configuration.

Pharm., 47, 368-410).-Si1ice epiosine, Y6H4*fl *NMe N>CH, has been found to possess physiological properties C,H;C- sikirar to those of morphine, the pharmacological action of the latter must be dependent on the presence of the phenanthrenoid group, Y6H4'g- c,H,*c*N= ' Y6'H4* :* OH Mwphig e nine h y dr ochlovide, , prepared by reducing phenanthraquinone hydrazone with stannous chloride, crystallises in coloured needles, becomes reddish at lSOo, but does not melt a t 290°, is decomposed by water, especially on heating, and is readily soluble in boiling glacial acetic acid or in hot concentrated hydrochloric acid, but only slightly so in the cold solvents. By the action of alkali hydroxides or carbonates on the hydrochloride, phenanthraquinone is regenerated.By the action of zinc chloride on morphigenine hydro- chloride, products were obtained which were not isolated, but their aqueous solutions had a distinct narcotic effect on dogs and frogs, Epiosine, prepared by the action of methylamine on morphigenine hydrochloride, was found to be identical with Japp and Davison's N-methylphenyleneimidazole (Trans., 1895, 67, 32) ; it melts a t 195'.The physiological actions of morphigenine hydrochloride and epiosine C6H4*C*NH,,HCl are described in detail in the original paper. E. w. w. ZCyanopyridine. By HANS MEYER (Monatslh., 1902,23,437-442. Compare Abstr., 1901, i, 407).-Picolinamide is best prepared by the action of aqueous ammonia on picolinyl chloride and extraction with chloroform. In the preparation of the amide from the ester, the solu- tion of the hydrochloride from the latter, obtained by passing hydrogen chloride into an absolute alcoholic solution of picolinic acid, is con- centrated and shaken with aqueous ammonia (compare Abstr., 1894, i, 425, 4'72). 2-Cymopyridine, prepared by the action of thionyl chloride on picolinamide at 90-1 OOO, crystallises from ether in long, colourless needles, melts at 26O, is slightly volatile at the ordinary temperature, boils at 212--215O, has an intense odour resembling those of benz-728 ABSTRACTS OF CHEMICAL PAPERS aldehyde and of coumarin, and is easily soluble in water, alcohol, ether, or chloroform.It has slight basic properties and forms an orange-red, crystalline platinichloride, (C,H,N,)~,H,PtCl,, and an aurichlorids, C6H,N,,H AuCl,, which crystallises in lemon-yellow needles, losing about lH,O and becoming opaque a t 100’; it melts a t 190’ and is sparingly soluble in water, dissolving easily in dilute hydrochloric acid. Picolinic acid forms an aurichloride which crystallises in glistening, straw-yellow leaflets, melts at 200”, decomposes with evolutim of gas at 204’, and is easily soluble in water.Picolinamide aurichlol-ide is an insoluble, light yellow, crystalline powder which sinters a t about 2 1 5 O , but melts only a t a much higher temperature. The aurichloride of 2-aminopyridine crystallises from concentrated hydrochloric acid in long, glistening, garnet-red needles and melts at 231”. 2-Cyanopyridine is hydrolysed by concentrated hyflrochloric acid at 120°, giving a quantitative yield of ammonia and picolinic acid. G . Y. Tetra-aquodipyridinechromium Salts. By PAUL PFEIFFER (Zeit. anorg. Chew,., 1902, 31,401--436).-Werner’s theory connecting the metal-ammonia compounds and salt hydrates is supported by the facts now known about the intermediate products. The author has investigated some of these intermediate products containing pyridine in place of ammonia.The chloride, CrC11,,2Py,6H20, loses 2 mols. of water in a desiccator containing phosphoric oxide and gives CrC1,,2Py,4Y20 ; therefore, according to Werner’s theory, i t is to be regarded as and is consequently an intermediate product between [CrPy,]Cl, and [Clr(H20),]C1,. I n aqueous solution, all the chlorine is ionised and i t undergoes metathetical reactions. Like the pure hydrates, i t gives basic salts such as [CrPy2(H20),(0H),]C1 when hydroxides are added. The salts are all red, crystallise well from water, and the aqueous solutions have an acid reaction. When heated, they give off pyridine and become green. The basic salts dissolve in acids, giving red solutions. because the basic salts dissolve in alkalis or ammonia.The author has already introduced a slight modification (Nctturwiss. Rundsch., 1901, 366) into Werner’s theory, According to the pro- position suggested, a definite place in the molecule is assigned to the negative radicle. For the tetra-aquodipyridinechromium salts, the formula X { (H20)2>Cr<2E$ is given, indicating that the position of one X is uncertain. The properties of the hydroxylopyridine salts which have been obtained indicate that they are not the basic salts corresponding with they are rather to be regarded as salts of pseudo-bases formed from the true bases by splitting off of water : [In the formulz given Py = C,NH,.] [CrPy 2(H20)41C13,2H20, It has not been possible to prepare the free base, W Y ,(H,O) (OHM 9 PY, This shows that these are oxonium salts.[CrPY,(H,O),IX, ; + 2 ~ 4 0 .ORGANIC CHEMISTRY. 729 The idea of pseudo-salts can also be advantageously applied to metal-ammonia compounds. The starting point for the preparation of the tetra-aquodipyridine- chromium salts is diuquodihydroxylodipyridineclwomiun,t chloride, LCrPg,(OH),( H,O),]Cl, which is obtained from green chromic chloride hexshydrate, I Cr(H20),Cl2]Cl,2H2O, by the actionof pyridine ; it may be prepared in like manner from the double salt, [Cr( H20),C1,],2HClPy, which is most easily obtained by adding successively pyridine and a large excess of concentrated hydrochloric acid t o a solution of chromic chloride; a third method of preparation is by warming CrC13Py, with a 10 per cent. solution of ethylenediamine. The diaquo- salt is obtained in fine needles which decompose at looo; i t is quite insoluble in the ordinary solvents, but can be recrystallised from pyridine.When the dihydroxylochloride is treated with concentrated hydro- chloric acid, the greenish-grey compound is converted into a red, crys- talline mass of tetru-aquodipyridineclrornium chloi*ide, [CrPy2(H,0),]C1,,2H20 or 01 { (H20)2>Cr<H~OC1 H OC1 + 2H20. This is very easily soluble in water, ethyl alcohol, or methyl alcohol, but insoluble in ether, acetonitrile, acetic acetate, acetic acid, or chloroform. The aqueous solution remains unchanged at the ordinary temperature, but decomposition occurs when i t is heated on the water- bath. The red, alcoholic solution quickly decomposes and deposits the greenish, basic chloride.The reactions with various reagents have been studied. I n the air, the salt is converted into the greenish-violet ?Lydroxylotria~uod~~yridinechl.omizcm chioride, [CrPy,(H,O),OH]Cl,. Tetra-uquodipyridinechromium bromide, lCrPy2(H2O),]Br,,2HzO, obtained from the dihydroxylochloride, or the normal chloride, by solution in concentrated hydrobromic acid, separates i n red crystals from concentrated hydrobromic acid solution. It closely resembles the chloride but is rather more stable. Dih,ydroxylodiaqzcodipyridine- chronzium bromide, [CrPy2( H,O),(OH),]Br, is almost quantitatively precipitated by the addition of pyridine to a solution of the normal bromide; it has a greenish tinge and is decomposed on heating. When the dihydroxylochloride is rubbed with sulphuric acid, a red solution is produce? from which flat, red needles of tetra-aquodi- pyridinechromium Iydrogen sulphute, S04[CrPy2( H20),]S04H, 2H20, separate.The salt is very easily soluble in water and the solution has an acid reaction ; i t is insoluble in alcohol or ether. When alcohol is added to the concentrated aqueous solution of this salt, violet crystals of tetra-aqzcodipyridinechl.omium sulphate, are formed. This sulphate remains unchanged in the air, but is decomposed by water ; when placed beside phosphoric oxide, it does not lose in weight. When a solution of the tetra-aquo hydrogen sulphate is precipitated with pyridine, fine, greyish-blue crystals of hydroxylo- Iriuquodipyridinechromium subhate, [CrPy,(H,O),( OH)]SO, separate ; the latter salt is soluble in much water to a greenish solution having a neutral reaction. 3 3 2 [CrPY2(H,O)412(S~4),,3H,O,730 ABSTRACTS OF CHEMICAL PAPERS.Tetra-aquodipyridinechromiwm chromicyanide, [CrPy,(H,O),1Cr(CN),,2H,P, is precipitated when potassium chromicyanide is added to a solution of the tetra-aquochloride containing some hydrochloric acid. It is obtained in red plates which are insoluble in water. Hydroxypyrazolone Derivatives of the Naphthalene Series. FARBENFABRIKEN VORM. F. BAYER & Go. (D.R.-P. 131537).-The hydrazine derivative obtained from 7-amino-a-naphthol-3-sulphonic acid, when condensed with ethyl acetoacetate in the presence of dilute acetic acid, gives rise t o hydroxypyrazolonesulphonic acid, which separates in granular crystals when the mixture is treated with excess of hydrochloric acid.This product yields a yellow nitroso-derivative. Other hydrazines of the naphthalene series may be employed in this condensation and the reaction also occurs with ethyl oxaloacetate or di h yd roxy t a r t aric acid. Chloro-m-phenylenediaminecarboxylic Acid. By PAUL COH.N and MARKUSCHIFFERES (Chern. Centr., 1902, i, 1293; from Zeit. Far ben- Text il-Chem. ,,I 9 02,1,205 -2 06). -4- CT~loro-m-phenyZenedic~mir~- 6-carboxylic acid or 2-chloro-3 : 5-diainino-1-benxoic acid, prepared by reducing 2-chloro-3 : 5-dinitrobenzoic acid with stannous chloride and hydrochloric acid, is very readily soluble in water and was not isolated, The hydrochloride, C,H~0,N2C1,2HCl, crystallises from alcohol in small, pale yellow needles.was also prepared, The dzacetyl derivative, C6H,CI(NHAc),*C0,H, crystallises from water in needles and melts a t 288-289’. 2-Amino- 3 : 5-dinitrobenzoic acid, on reduction with stannous chloride and hydrochloric acid, forms 2 : 3 : 5-triaminobenzoic acid. The free acid prepared by treating the solution of the hydrochloride, C7H902N3, 3HC1, with sodium acetate quickly becomes red. The sulphate forms brownish-yellow needles and is almost insoluble in water. E. W. W. 3-Arnino-4methylpheno-fl-naphthacridine. FRITZ ULLMAN (D.R.-P. 1 30943) .-3-Amino-4-methyZp7eno-~-naphthacridine, formerly obtained by condensing 2 : 4 : 2’ : 4’-tetra-amino-3 : 3’-ditolylmethane with P-naphthol, is now prepared by heating the latter compound at 200° with the product, C8HloN2, formed by the interaction of form- aldehyde and tolylene-8 : 4-diamine in molecular proportion, the reaction being effected in neutral solutions.Proteids of Yeast. By R. SCHR~DER (Beitr. chem. Physiol. Rath., 1902, 2, 389--403).-Tbe proteid substance, which can be obtained from yeast by treatment with ether and water, and can be precipitated from this solution by heating, gives all the proteid reactions ; the lead reaction is feeble. By decomposition with acids, it yields leucine, tyrosine, phenylalanine, and bases. The bases contain about a quarter of its total nitrogen, and of them lysine is the most abundant. A J. MUG. G. T.

Melanins which Originate from Proteid. By FRANZ SAMUELY (Beitr. chem. Physiol. Puth., 1902, 2, 355-388).-The ill-characterised and probably numerous substances, named melanins and melanoidins, can be artificially prepared from proteids. I n their formation, the tyrosine group, and especially the heterocyclic nucleus (pyrrole, pyr- idine, skatole) of the proteid appears to be important. The relationship of these substances to humin is discussed. W. D. H. The Albumose Precipitates produced by Papain and Rennin (Coaguloses and Plasteins). By D. KURA~EFF (Beit?.. chem. Physiol. Pccth., 1902,2,411-424).-The precipitates produced by adding rennin and papain to various albumoses and caseoses were examined and analysed.These substances are probably closely related to anti- albumid, and possibly to bacterial coagulins. These are characterised by a high percentage of carbon and a low percentage of nitrogen, so differing from the proteoses. Decomposition of Proteids. By H. STEUDEL (Zeit. physiol. Chem., 1902, 35, 540-544).-The usual method of obtaining hexon bases from proteids is by means of mineral acid. If boiling baryta water is used instead, the proportion of the bases is different, lysine being by far the most abundant. Whether this is due to the destruction of the other bases during the boiling is uncertain. The decomposition of proteids produced by ferments is very similar to that produced by bary ta, W. D. H. The Nucleo-proteid of the S u p r a r e n a l Gland. By WALTER JONES and G. H. WHIPPLE (Amer. J. Physiol., 1902, 7, 423--434).-- This substance is not a nucleo-histon, and its composition is identical whether prepared from the ox or sheep. It is closely similar t o t h a t obtained from the pancreas. On decomposition, i t yields guanine and adenine in the same relative proportion. Xanthine, hypoxanthine, and epiguaiiine are either absent or present in the merest traces. As these three bases were found by Okerblom (Abstr., 1899, ii, 778) in suprarenal extracts, there is an interesting and curious differ- ence between the bases preformed in the gland and those which result from the hydrolytic decomposition of its nucleo-proteid. The Constitution of Proteid Cystin. By ERNST FRIEDMANN (Beit?*. chem. Phylsiol. Path., 1902, 2, 433--434).-The older physiologists re- garded the sulphur-containing complex in a proteid as the source of taurine. Recent research has shown that the sulphur-group of proteid is cystin or cystein. The possibility of its transformation into taurine is excluded if Baumann is correct in considering that cystein is a-aminothiolactic acid, SH*CMe(NH,)-C0,H. The present research shows that the cystin from proteid is different from ordinary cystin. Proteid cystein is a compound of P-thiolactic acid, SH.CH;CH(NH2)*CO,H. By the usual treatment, this W. D. H. W. D. H.732 ABSTRACTS OF CHEMICAL PAPERS. can be changed into cy steic acid (aminosulphopropionic acid), S0,H*CH2*CH(NH2)*C02H, and from this, by the loss of carbon dioxide, taurine, S0,H*CH,*CH,*NH2, is obtained. Proteid cystein is thus a derivative of glyceric acid, not, as with mercapturic acid cystein, of pyruvic acid, and stands in close relation- ship to serin. W. D. H. Action of Iodine on Proteids. I. By C. H. L. SCHMIDT (Zed. physiol. Chem., 1902, 35, 386-395. Compare this vol., i, 251).-The amount of amic nitrogen eliminated from the proteid molecule dur- ing iodination is a function of the concentration of the iodine solution used; the more concentrated the solution, the greater is the amount of iodide and iodate formed and the less that of hydriodic acid. J. J. S. Experiments :on Malt Diastase. By ARTHUR R. LING and BERNARD F. DAVIS (J. Ted. Inst. Brewing, 1902, 8, 475-495).- When diastase from well-grown, low-dried malt is allowed to act on starch paste of 2-5 per cent. strength at 50-60°, the starch is hy- drolysed in about 18 hours to a point a t which [aJD .1.93 is 149*5-150° and the cupric reducing power R,.,, is 77-78, whilst after 42 hours these constants are substantially those of maltose, and in such a solution nothing but maltose can be detected. Diastase prepared from malt grown under abnormal conditions (such as small quantities prepared in the laboratory) and diastase which has been slowly heated to 115-120° do not hydrolyse the starch completely to maltose, even if allowed to act in large excess ; diastase which has been rapidly heated t o 115-120" produces a more pronounced effect. Keither the fhal temperature at which a sample of malt has been kilned (considered alone), nor the '' diastatic power " determined in accordance with Kjeldahl's '' lam of proportionality " by Lintner's method, is a criterion of its behaviour towards starch. When a dias- tase solution is heated above 65", its reaction with starch paste appears to be quite different to that of a solution which has not been heated above 60"; this is shown, not only by the specific rotatory and cupric reducing power of the dissolved matter, but also by the presence of dextrose among the final products of hydrolysis. E. G. Catalase. By OSCAR LOEW (Zeit. Biol,, 1902, 43, 256-257).- The ferment in milk which causes decomposition of hydrogen peroxide has been termed superoxydase by Raudnitz. It is identical with the ferment previously named catalase by the author (Abstr., 1901, i, 435). W. D. H.

By OSCAR PILOTY (Ber. 1902 35 3090-3093).- Comparing the properties of the nitroso-compounds described in the two following papers the author concludes that there is no essential difference between nitroso-compounds and the bisnitrosyl compounds which contain the N202 group. Ou the contrary the transition from the one class to the other is gradual ; the typical nitroso-compounds are unimolecular liquids or crystallised solids of a deep blue colour; some nitroso-compounds form colourless solids which become blue when melted or dissolved and these are bimolecular in the cold and contain the N20 group. The difficulty of resolving the N20 group into two NO groups increases until finally the typical bisnitrosyl compounds are arrived at and these no longer shorn the blue colour under any conditions.J. McC. Constitution of +-Nitroles and some Bromonitrosohydro- carbons. By OSCAR PILOTY and A. STOCK (Ber. 1902,36,3093-3101). -Propyl-$-nitrole prepared from /I-bromo-p-nitrosopropane by shakingORGANIC CHEMISTRY 735 in ethereal solution with silver nitrite forms white crystals which melt at 76". p-Bromo-p-nitrosobutu~~ formed when methylethylketoxime in aque- ous solution is treated with bromine in presence of pyridine is a deep blue volatile liquid which boils a t 2 8 O under 19 mm. pressure and has a sp. gr. 1.360 a t 2 2 O . With silver nitrite it gives butyl-+-nitrole which melts at 6 8 O . I n the same way from diethylketoxime PJworno-p-nitrosopentacne is formed as a liquid which boils at 4 9 O under 17 mm.pressure and has a sp. gr. 1.325 a t 20°; with silver nitrite it gives amyl-enitrole melting a t 63.5'. By the action of bromine in presence of pyridine on the oxime obtained by treating pinacolin with hydroxylamine y-bromo-y-nitroso- /3/3-dimet?~ylbutccne is produced It forms volatile blue crystals with an odour recalling that of camphor. The formation of bromonitroso-compounds is a useful test for ketones. The solution to be tested should be made neutral and to it a drop of a 10 per cent. solution of hydroxylamine hydrochloride and one of a 5 per cent. solution of sodium hydroxide added. A large drop of pyridine is introduced and a thin layer of ether poured on after which it is shaken with sufficient bromine to impart a yellow colour to the ether.If on addition of hydrogen peroxide the ether becomes blue the presence of a ketone or ketonic group may be concluded. When butyl-+-nitrole is dissolved in anhydrous hydrogen cyanide a t - 10") the solution is colourless ; the depression of the freezing point of the hydrogen cyanide was observed and again after standing when the solution had become quite blue. It was found that the second de- pression was exactly double the first indicating that in the colourless form the +-nitrole has a doubled molecular formula. From the transformation of the bromonitroso-compounds into +nitroles with silver nitrite the authors conclude that the former are true nitroso-compounds. J. McC. Halogenated Nitroso-compounds of Diketocyclohexamethyl- ene and a Secondary Nitrorso-compound By OSCAR PILOTY and HERMANN STEINBOCK (Bey.1902,35,3101-3117).-By the action of bromine in presence of pyridine on the dioxime of p-diketocyclo- hexane 1 4-dib~omo-1 4-dinit~osocyclohexane is formed ; i t crystal lises in deep blue rhombic pyramids melts a t 89" and is very easily soluble in alcohol acetic acid ether or benzene. I n this reaction it is the cis-tram-modification which is formed and there is also produced 1 4-dibrorno-1 4-bisnityosyloyclol~exane which is colourless and insoluble in ether. Nitric acid or chromic and acetic acids transform the nitroso- compound into 1 4-dibromo-1 4-dinitrocyclohexane which melts at 168" and is insoluble in water but easily soluble in alcohol ether or acetic acid. When a current of chlorine is passed through a cooled hydrochloric acid solution of p-diketocyclohexanedioxime the cis-trcms-modifica- tion of 1 4-dichloro-1 4-dinitrosocyclohexane is produced.It is formed much more easily than the corresponding bromo-compound and does not require the presence of pyridine. It forms deep blue monoclinic 3 f 27'36 ABSTRACTS OF CHEMICAL PAPERS prisms melts at 108*5' and is easily soluble in the common organic solvents. When hydrogen chloride is passed through a solution of it i n glacial acetic acid it changes into 1 4-dichloro-l 4-bisnitrosyZcyclo- hexane which separates in colourless crystal& This represents a new class of intermolecular bisnitrosyl compounds for which the formula AH CH,\ developed is CClLg202L'CCl. It is soluble in methyl alcohol \cH,-cH,/ acetone or acetic t o colourless solution which when heated becomes blue and again colourless when cooled.This characteristic reaction is attributed to its conversion into a nitroso-compound at the higher temperature. With chromic and acetic acids the chloronitroso- compound gives 1 4-dichloro-1 4-dii~itrocyclohexune as a greenish substance which melts a t 178" and is soluble in the ordinary organic solvents. By the action of chlorine on benzaldoxime a very unstable blue substance is formed which the authors believe t o be o-cldoro-w-nitroso- toluene CHPhC'l* NO. With acetaldoxime in hydrochloric acid solution chlorine gives mdnochloronitrosoethane which can be obtained i n colourless plates ; it dissolves in ether or methyl alcohol with a deep blue colour and melts at 65" to a blue liquid which becomes colourless on solidifying.It is spontaneously transformed into acetohydroximic acid chloride (CHMeCI-NO - CMeCl:N*OH) which solidifies at - 3". When dis- solved in hydrochloric acid and treated with chlorine this hydroximic acid chloride gives dichZoronitrosoethane CH,*CCl,*NO as a liquid which boils at 68'(corr.) ; it is miscible with alcohol ether or benzene but not with water and has a sp. gr. 1.2521 at 19'. The constant for the molecular depression of the freezing point of anhydrous hydrogen cyanide has been determined t o be 21.7 and a normal molecular weight has been found for dichloronitrosoethane in this solvent. J. McC. Formation of Alcohols by the Electrolysis of the Salts of the Fatty Acids.By HANS HOFER and M. MOEST (Annalen 1902 323 284-323).-Methyl alcohol is produced when sodium acetate is electrolysed in aqueous solutions containing sodium per- chlorate ; under similar conditions the corresponding propionate and n- and iso-butyrates give rise to ethyl and n- and iso-propyl alcohols respec- tively. Sodium succinate yields hydracrylic acid instead of ethylene glycol. Other inorganic salts induce this reaction namely chlorates sulphates carbonates and hydrogen carbonates. The aldehydes corre- sponding with the alcohols are also formed during the electrolysis. Only small quantities of the alcohols and aldehydes are obtained on electrolysing valerates and hexoates. The communication includes a detailed account of the apparatus employed and tables indicating the composition of the gases produced with solutions of varying concentration (compare Abstr.1894 i 228 ; 1896 i 10 664). By Lours HENRY (Bull. Acacl. Roy. Belg. 1908 445-494).-The action of alcohols on esters is not G. T. M. Action of Alcohols on Esters.ORGANIC CHEMISTRY. 737 dependent simply on the reactive intensity nf the alcohol (measured by its esterification velocity for acetic acid) except in the cases of the action of methyl or ethyl alcohol on amyl glyceryl and cellulose nitrites (compare Bertorii Abstr. 1886 217 and 1887 458) and of the same alcohols on mixed acid anhydrides (compare Behal Abstr. 1899 i 734) which the author regards as a class of esters. In many cases the action is modified by the reactive intensity of the acid residue of the ester thus pyruvyl formate CH,Ac*O*CHO is decomposed by methyl alcohol with the liberation of pyruvyl alcohol (a small amount of the corresponding ether melting at 130' i& also formed) whilst pyruvyl acetate is not attacked. Temperature is also an important factor thus whilst amyl nitrite is decomposed in the cold by methyl or ethyl alcohol it is not attacked by propyl or butyl alcohol until heated although these possess higher reactive intensities than amyl alcohol.I n some cases the effect of temperature is to invert the action altogether thus glycol when boiled with diethyl succinate liberates ethyl alcohol although the reactive intensities of the two alcohols are respectively 66% and 53.9 the abnormality being due to the greater volatility of ethyl alcohol (compare Vorlander Abstr.1895 i 17). It is probable also that solubility plays a considerable part in influencing actions of this type. Functional inertia of the alcohol may also be overcome by greatly increasing ifs reacting mass relatively to that of the ester (compare Walker Abstr. 1893 i 500 and Vorlander loc. cit.) Reactive intensity in a homologous series of alcohols decreases as the series is ascended and the same result is produced by the intro- duction of negative groups such as OH C1 CO the effects of these increasing with their proximity t o the original OH group of the alcohol (compare Heintx AnmZen 1861 114 440 ; Bertoni Zoc. cit. ; Richter this Journal 1877 ii 439; Rose Abstr. 1881,251 ; Bachmann Abstr. 1883 726 ; Behal Zoc.cit. ; Henry Abstr. 1901 i 577 ; Vor- lander Zoc. cit.) where reactions illustrating this general statement are to be found. In the original paper explanations of these reactions embodying the foregoing views are given. T. A. H. Mono-ethers of Bivalent Alcohols. By M. H. PALOMAA (Ber. 1902 35 3299-3301).-By treating ethylene glycol with sodium and an alkyl iodide the mono-ethers are obtained.

The mono-n-propyl ether of ethylene glycol Pr*O*CH,*CH2*OH boils at 152-153O and has a sweet odour and a sp.gr. 0.9159 at 19'/19O. J. McC. Products which are Formed by simultaneously passing Dry Sulphur Dioxide and Ammonia into Absolute Alcohol dis- tilled over Sodium. By ALWIN GOLDBERG and M. R. ZIMMEBMANN (Zeit. angew. Chern. 1902 15 898-906).-The ammonium sulphites,738 ABSTRACTS OF CHEMICAL PAPERS. obtained by passing sulphur dioxide and ammonia into absolute alcohol were first prepared by Muspratt (Annabn 1844 50 269) and sub- sequently studied in detail by Schumann (Abstr. 1900 ii 271). Divers (Trans. 1899 75 533) prepared ammonium ethyl sulphite by using carefully dried alcohol and a low temperature - 15'. The authors have prepared the same compound which they call dmnzonium ethoxysulphinate a t the ordinary temperature ; it is decomposed by hot water into ammonium pyrosulphite and alcohol. Ammonium methoxgsulphinate OMe*SO*ONH is prepared similarly as are also the analogous derivatives of amyl alcohol methylethylcarbinol and trimethylcarbinol. The co?xpound from allyl alcohol is formed by union of 3 mols.of ammonia and sulphur dioxide respectively and 2 mols. of allyl alcohol; from the fact that only two-thirds of the sulphur dioxide can be titrated by iodine the salt is represented by the formula ONH,*SO*O*[CH,'],*SO,*CI-12*CH(NH,)*CH2*O*S0*ONH,. On leading ammonia into molten ammonium ethyl sulphite a t 99' ammonium aminosulphinccte NH,*SO*ONH is formed. When am- monium ethyl sulphite is heated ammonium sulphate is formed; when heated under pressure with absolute alcohol or ethyl bromide am- monium sulphate and thiosulphate are produced ; if the salt is heated alone under pressure besides ammonium sulphate and sulphur a yellow oil C,HI,O,S which is volatile with steam is obtained.Ammonium methyl sulphite decomposes in a similar manner. Action of Acid Chlorides and Anhydrides of the Fatty Series on Trioxymethylene. By MARCEL DESCUD~ (Bull. Xoc. Chim. 1902 [iii] 27 867-871. Compare Abstr. 1901 i 644 and this vol. i 149 339 451)-When trioxymethylene reacts with acetyl chloride in presence of zinc chloride there are formed chloromethyl acetate dichloromethyl oxide and methylene diacetate ; the last which boils tit 170° is also formed by the action of acetic anhydride on trioxymethylene in presence of zinc chloride. In this reaction there is also produced methyleneoxide diucetate (Me*CO,*CH,),O which distils a t a temperature of 204-207'.I n a similar manner there have been prepared chloromethyl propionate boiling a t 128-130° sp. gr. 1.140 ; mthylene dipropionccte boiling a t 190-1 92' sp. gr. 1 a503 ; chloromethyl isobutyrate boiling a t 138-140° sp. gr. 1.080 ; methylene diisobutyrate boiling at 197-199' sp. gr. 0.998 ; chloromethyl butyrate boiling a t 150° sp. gr. 1.094; methylene dibutyrate boiling at 215-216" sp. gr. 1.017 ; in all cases the boiling points were determined under a pres- sure of 745 mm. and the sp. gr. taken at 20°/20'. Some of the commercial specimens of trioxymethylene are not suit- able for the above reactions but a suitable specimen can be obtained by slowly evaporating a solution of formaldehyde.By H. G.

At temperatures below 700" there were obtained (A) pyroligneous acid 34 per cent containing acetic acid 2.9 and methyl alcohol 2.9 per cent.; (B) tar 17.7 per cent. contain- ing light oil 8-0 creosote oil 10.0 pitch 18.0 and water 64.0 per cent. ; (C) charcoal 29 per cent.and (D) gases 19.3 per cent. The gas is non-illuminating; the charcoal is soft and contains little ash. The creosote oil boiled from 160-250° and contained 17 per cent. of creosote of which 9.5 per cent was guaiacol. The light oil which boiled between 40Oand 150° was fractionated and contained small amounts of aldehydes and ketones and considerable amounts of the methyl and ethyl esters of formic acetic propionic and butyric acids. The results of the fractionation and tohe yield of the products are tabulated in the original. Behaviour of Certain Acyl Chlorides towards Agents which eliminate Hydrogen Chloride. By EDGAR WEDEKIND (Annalen 1902 323 246-257).-Acetyl chloride when treated with triethylamine dissolved in benzene loses hydrogen chloride and 4 mols.of the residue condense to form dehydracetic acid; its next homologue propionyl chloride behaves differently under these condi- tions giving rise t o a trimeric condensation product. Compounds of similar complexity have also been obtained from phenylacetyl chloride and dihydrocinnamyl chloride. Dehydracetic acid also results from the action of ferric chloride on acetyl chloride. The homologous chlorides of the fatty series when condensed with dry metallic chlorides yield high-boiling oils the con- stitution of which is not yet known. Benzoyl chloride and phenyl- acetyl chloride do not give rise to ketones under the influence of ferric chloride. The aromatic acyl chlorides containing a t least three carbon atoms in the side chain condense to form cyclic ketones ; dihydro- cinnamyl chloride yields hydrindone whilst phenyl-n-butyryl chloride and phenyl-n-valeryl chloride furnish a-ketotetrahydronaphthalene and pheno-a-ketocycloheptane respectively.Cinnamyl chloride does not however condense to form an indenone. Aluminium chlorido also serves to promote these condensations. I n ethereal solutions the acyl chlorides under the influence of the an- hydrous metallic chlorides give rise to the ethyl esters of the corre- sponding acids. G. T. M. T. A. H. Nature of Radicles. By EDGAR WEDEKIND (Annalen 1902,323 267-264. Compare Vorlander this vol. i 309 ; ii 250).-Ethyl chlorocarbonate does not form additive products with the strong tertiary bases although it is readily decomposed by these substances the action being accompanied by an elimination of hydrogen chloride.It follows therefore ,that this acyl chloride conforms t o the author's rule that two negative groups one of which is a strongly acidic radicle do not under ordinary conditions form additive products with the tertiary amines. The author's study of the interaction of acyl chlorides and the tertiary bases leads to the following conclusions. The more rapid and complete is the interaction of these reagents the740 ABSTRACTS OF CHEMICAL PAPERS. greater is the probability. of an elimination of hydrogen from the molecule of the acyl chloride and the consequent formation of bye- products. On the other hand the slower the elimination of hydrogen chloride the greater is the tendency for the intervention of' moisture leading to the production of acid anhydrides.Pyidine picrgl chloride C,NH,Cl*C H (NO,) results from the addition of picrgl chloride to pyridine6; St is a yellow amorphous powder readily decomposed by water or the hydroxylic solvents with the production of pyridine picrate.

Soc. 1902 34 501-503).-Contrary to the observations of some other investigators the chief constituent of linseed oil is found to be linolic acid together with 23-25 per cent; of linolenic acid and about 5 per cent. of solid fatty acids. The linolic acid contained in linseed oil is apparently isomeric with those obtained from cotton-seed oil and sunflower oil.The tetra- bromostearic acid prepared from linseed oil is difficult to obtain in a solid state and then forms an amorphous mass melting a t 98-101° whilst the similar acid from other oils is distinctly crystalline and melts at 114-1 15O.

The substances are all lsvorotatory a fact which is contrary to Guye's hypothesis.The rotation of the last two compounds could not be determined exactly. The rotatory power of the monosubstituted esters increases as the concentration is increased and as the temperature is lowered.

By OTTO DIELS and HANS JOST (Ber. 1902 35 3290-3299).-Diacetyl can be conveniently prepared from methyl ethyl ketone by treatment with amyl nitrite and boiling the isonitroso- ketone formed with an acid.Diacetyl when shaken with concentrated hydrochloric acid is converted into termoleculav diucetyl C,,H,,O which melts at 105' boils at 280' and is sparingly soluble in water but easily so in organic solvents. This polymeric diacetyl does not reduce Fehling's solution permnnganate or silver solution. It is quite stable i n presence of alkalis but mineral acids decompose it into diacetyl acetic acid and other substances not yet identified. With acetic anhydride it gives a nzonoacetyl derivative which melts a t 93'. It forms a PJtenyZurethane which crystallises from benzene with one mol. of benzene of crystallisation melts at 86" or after freeing from benzene at 132' (corr.).With phenylhydrazine in presence of acetic acid it gives the ordinary osazone of diacetyl. It forms a p-nitro- phenylhydraxonc which melts at 200" (corr.) a n oxime which melts at 174-175" (corr.) and a semicurbaxone melting at 238' (corr.). The acetyl derivative gives a semicarbaxone which melts at 206' (corr.). When reduced with sodium amalgam the polymeric diacetyl yields p-xylGquinol and a substance which is probably dimethyl- cyclohexanone. The latter gives a ssmicarbaxone melting a t 198" (corr.).

By EMIL EISCHER and E.FRANKLAND ARMSTRONG (Ber. 1902 35 3141-3144).-Herzfeld (Ber. 1895 28 442) has shown that beaz- aldehyde may replace hydrochloric acid in the decomposition of phenyl- hydrazones. A similar method cannot be adopted in the case of tlie phenylosazones of the monosaccharides since in most cases they are not sufficiently soluble in water. The phenylosazones of disaccharides however are completely decomposed when their aqueous solutions ai e boiled for a short time with benzaldehyde and good yields of the osones are obtained. The method is also applicable to the osazones of arabinose and xylose which are soluble in hot water. Maltosone has been obtained in the form of a syrup which sets to a vitreous amorphous mass. It reduces Fehling's solution and reacts with phenyl hydrazine yielding maltosazone ; with p-bromophenylhydrazine it yields p-brornophenylrnaltosazone which crystallises in yellow needles melting and decomposing a t 198' and only sparingly soluble in the ordinary solvents with the exception of hot alcohol.

J. 1902 28 83-107).-Franklin and Kraus (Abstr. 1900 ii 382) have shown that a close analogy exists between liquid ammonia and water as electrolytic solvents and that acid and basic amides bear a relation t o liquid ammonia similar in many respects to that of ordinary acids and bases to water.From these considerations it seemed probable that reaction would take place between an acid and a basic amide in liquid ammonia with the facility which marks the inter- action of ordinary acids and bases in water. This has been found to be the case by means of a large number of experiments carried out in a specially devised apparatus. Potassamide i s very soluble in liquid ammonia and separates from concentrated solutions as a C O ~ O U I ~ B S ~ well crystallised hygro- scopic mass. When potassamide (I mol.) and acetamide (1 mol.) are allowed to react in presence of liquid ammonia hydrogen is evolved and crystals of potussiumacetumide CH,*CO*NHK,nNH separate from the solution ; this substance is also formed by the action of potassium on a solution of acetamide in liquid ammonia.When left in the air the crystals lose their ammonia of crystallisation and become opaque. By the action of potassium amide (2 mols.) on acet- amide (1 mol.) a dipotussiumacetamide CH,*CO*NK? is produced. The mono- and di-potassium derivatives of benzamlde benzenesulph- onamide m-methoxybenzenesulphonamide p-methoxybenzenesulphon- amide sulph'amide and carbitmide and the mono-potassium derivatives of phenlyacetamide and p-toluenesulphonamide were also prepared.

The formation of this compound is probably due t o the action of the alkali on the potassium ethylstannite at first formed according t o the equation 2SnEtO.OK = SnEt,O + Sn0,K2. Genesis of Naphthenes and Naphthenecarboxglk Acids By OSSIAN ASCHAN (An~aclen 1902 324 1-39).-The author's experimental results support; the theory which assumes t h a t the naph- thenes and their carboxylic acids are secondary products of the distil- lation of mineral oil in the earth's interior being formed by the polymerisation of compounds of the olefine series which result from the initial decomposition of fossil fat.Although ethylene when dissolved in carbon disulphide and treated with anhydrous aluminium chloride does not at the ordinary tempera- ture undergo any polymerisation yet under these conditions the crude amylene derived from amyl alcohol gives rise to saturated hydro- carbons. The products of lowest boiling point contained in the fractions 32-35" and 35-40' consist chiefly of a saturated hydro- carbon C5HI0 closely resembling methylcyclobutane. The next fraction 56-62' contains a hexane C6HI4 which corre- sponds in boiling point with &-dimethylbutane or /3-methylpentane. The addition of a methyl group t o the amylene carbon chain by the action of aluminium chloride has hitherto not been observed. The ammonium salt R. H. P. R. H. P. VOL. LXXXII.i. 3 9750 ABSTRACTS OF CHEMICAL PAPERS. The fraction 76-81' contains a saturated hydrocarbon C6H12 The fraction 150-200' appears to consist of a mixture of paraffins When pure amylene (b. p. 37-39'} is employed in these experi- ments the fraction 55-40' probably contains a branched chain hexane whilst the fraction 260-265' consists chiefly of naphthenes mixed with small quantities of the paraffins C,,H,,. The tarry residues of these fractionations when distilled under diminished pressure yield a hydrocarbon C38H66 boiling a t 190-220' under 30 mm. pressure. I n one series of experiments cyclohexane when heated with fuming hydriodic acid a t 300° became converted into methylcyclopentane. A negative result was obt'ained in a second series of experiments. cycZoHexane also undergoes transformation when left in contact with anhydrous aluminium chloride.It was not found possible to oxidise methylcyclopentane to a cyclic monocarboxylic acid ; dibasic acids only were obtained namely suc- cinic adipic and a trace of glutaric acid. I n one case act-dimethyl- propionic and isovaleric acids were identified these products being prob- ably due to the oxidation of the paraffins present in the methylcyclo- pentane. When treated with dilute nitric acid the cyclic hydrocarbon becomes oxidised to a mixture of acetic and succinic acids. corresponding in composition with cylcohexane. (AOH22' CllH24' and Cl2H26* G.

Compare Abstr. 1901 i 78).-When a solution of iodine is added to triphenylmethyl or one of its additive products dissolved in an appropriate solvent 80 per cent of the theoretical yield of triphenyliodomethane is formed (Zoc.cit.). When the solvent is petroleum the substance separates in yellow prisms which melt a t 131-132’ and are soluble in benzene carbon disulphide and hot ethyl acetate but insoluble in ether. It reacts like the corresponding bromo- and chloro-derivatives w hen treated with water alcohol and metals and like them forms coloured additive compounds with the chlorides of tin zinc and antimony. With ammonia and amines triphenyliodomethane also reacts in the usual manner furnishing with ammonia triphenylaminomethane ; with ethylamine triphenylmethyl- aminomethane ; and with aniline toluidine &c. similar derivatives. When the amount of iodine calculated for the formula CPh,I,I is added to a solution of triphenyliodomethane prepared as already described there separates a penta-iodide of the above formula as dark blue lustrous needles which melt a t 90’.With sodium thiosulphate only the “external” iodine is attacked with the formation of triphenyliodomethane and ultimately triphenylcarbinol. Alcohol converts the penta-iodide into triphenylmethane but if the hydrogen iodide first formed be removed by addition of zinc dust triphenylcarbinyl ethyl ether is obtained. Zinc dust when added to neutral solutions of the periodide furnishes triphenylmethyl.. Triphenylbromomethane penta-iodide CPh,Br,I (compare Abstr. 1899 i 155) prepared by addition of the calculated quantity of iodine to solutions of triphenylbromomethane separates as an oil which becomes crystalline in it few seconds.It is slightly soluble in benzene or carbon disulphide but readily so in ether. Its reactions are similar to those of the preceding compound.

Prerichs and Beckurts (Abstr. 1901 i SO) repeated his experiments and came to the con- clusion that all his compounds with the exception of the supposed thiocyanoaceto-p-toluidide were normal thiocyanates ; they found however that by the action of potassium thiocyanate on an alcoholic solution of chloroacetop-toluidide for only a short time a labile com- pound which they regarded as thiocarbiminoaceto-p-toluidide C,H,Me*NH*CO*CH,*NGS was produced ; they further observed that when the solution was warmed this labile compound was rapidly con- verted into a substance supposed t,o be thiocyanoaceto-p-toluidide and that the latter was quickly changed into p-tolylthiohydantoin.The present authors have prepared the thiocyanoacetanilides according to Grothe's directions and have found that although the aniline o-toluidine and p-xylidine compounds are correctly described the so-called t hiocyanoace to-p- to1 ui dide and t hioc yanoacety 1-p- phene t- idide are neither thiocgano- nor thiocarbimino-derivatives ; the p-tolu- CK,-S co<iY(C,H4Me)*&NH ' idine compound is a labile $-tlpiohydantoin whilst the p-phenetidine compound is the stable p-phenetyl-$-thio- hydantoin 'O< .(!J~N.(T~,.OEL,' The molecular rearrangement CH2* SORGANIC CHEMISTRY. 759 of thiocyanoacetanilides into the stable hydantoins does not involve the formation of a thiocarbimino-derivative a t any stage.Thiocyanoacetanilide crystallises in colourless acicular prisms and melts a t about 91" ; if recrystallised from alcohol it melts at S6-SS0 and when crystallised from benzene it contains benzene of crystallisa- tion which is rapidly lost on heating or on exposure to -the air. By the action of the calculated quantity of thioacetic acid on it acetylthio- glycollarzilide SAc*CH,*CO.NHPh is produced which crystallise8 from alcohol in colourless needles and melts at 97-98'; the same compound may be obtained by the action of sodium thioacetate on chloroacetanilide. I n two experiments in which thiocyanoacet- anilide mas heated with an excess of thioacetic acid a substance (prob- ably an acetyldithiourethane) was obtained which crystallises in slender needles and melts and decomposes at 192'; in other experi- ments a dithiouretlmn.e NH,*CS*S*CH,*CO*NHPh was produced which crystallises in square plates melts a t 162O and is converted by the action of alkali hydroxide into alkali thiocyanate and a salt of thio- glycollanilide.

Thiocyanoaceto-o-toluidide melts a t 102-103' as stated by Grothe but if warmed with ether for two hours or repeatedly crystallised from benzene it melts a t about 109'.

The formation of cyanic acid is determined by conversion into carbamide.The formation of diphenylcarbamide when carbaminethioglycollanilide is treated with aniline and the formation of methylthioglycollanilide when the carbamine is heated with methyl iodide and sodium methoxide (Rizzo) are explained by the decomposition of the carbamine into thio- glycollanilide and cyanic acid when warmed with alkalis or organic bases. The decomposition also takes place when the carbarnine is heated above its melting point. Thioglycollanilide melts at 11 1-1 12' (Rizzo m. p. 105-1070) and is best obtained by warming the carbamine with alcoholic ammonia (com- pare Liebermann Anncclen 1881,207 129). A small part of the pro- duct is oxidised to dithiodiglycollanilide which is insoluble in alcohol. Grothe's compounds (Abstr.1901 i SO) are formed when chloro- acetanilides are heated with potassium thiocyanats in alcoholic solution for 15 minutes When chloroacetanilide is heated with potassium thiocyanate in alcoholic solution for several hours phenylthiohydan- toin (m. p. 178") is formed (compare Rizzo Eoc. cit.). When warmed with fuming hydrochloric acid the thiocyanoacet- anilides are converted into carbaminethioglycollanilides.

Lincei 1902 [v] 11 i 555-561). -The products of hydrolysis of most compounds such as esters amides &c. are usually the same whether the decomposition is brought about by means of acids or alkalis but with hydroxylaminesulphonic acids benzenesnlphohydroxamic and nitrohydroxylarninic acids this is not the case Thus with alkalis these compounds yield a nitroxyl group and the corresponding acid either sulphurous acid or a sul- phinic acid RHSO and nitrous acid.With acids however the first two of the above compounds yield hydroxylamine together with sulphuric acid or a sdphonic acid R*SO,H whilst nitrohydroxyl- aminic acid loses immediately a mol. of water and gives nitrogen dioxide. To obtain further informxtion as to the mechanism of this hydrolytic action the authors have prepared and studied hydroxamic acids of sulphur of the following types which readily lend themselves to such decomposition R*SO,*NH*OH ; R*SO,*NRl*OH ; R*S02*NH*OR1 ; R*S02*NR1*OR2; R representing an aliphatic or aromatic residue and R1 and R2 aromatic aliphatic or acid residues. The acids studied of the first hype namely C,,H,a*SO,*NH*OH;SO,Et *NH*OH; C,H,( SO,*NH*OH),; and C,,H,(SO,*NH*OH) which are analogous to the acid prepared by Piloty (Abstr.1896,i 555) behavesimilarly to benzenesulphohydroxamic acid The alkaline hydrolysis was carried out in presence of either a n aldehjde or nitrosobenzene the nitroxyl group split off being thus converted into either a hydroxamic acid or nitrosophenylhydroxyl- amine. In the cage however of a-naphthalenesulphohydroxamic acid the residue after the removal of nitroxyl undergoes molecular re- arrangement yielding p-naphthalenesulphinic acid. When sulphohydroxamic acids in which two atoms of hydrogen are replaced by acid radicles for instance C,H,*SO,*~Ac*OAc and C,,H,~SO,*NAc*OAc are hydi olysed in presence of alkali they ex- hibit a similar behaviour to the above. The same is the case with the acid C6H,*S0,*NPh*OH which yields benzenesulphinic acid and nitrosobenzene (corresponding with the nitroxyl residue) and with C,H,.SO,*N(CH,Ph)*OH which gives nitrosotoluene this soon under- going transformation into benzaldehyde.The above behaviour is explained by supposing t h a t i n alkaline VOL. LXXXII. i. 3 h766 ABSTRACTS OF CHEMICAL PAPERS solution these compounds react as if they possessed the tautomerio structure R*SO(OH) NOH. Substituted hydroxamic acids of the type R.SO,*NH*ORl where R1 represents an alcoholic residue do not however exhibit such a reaction. Thus the acid C6H,*S02*NH*O*CH2Ph can be precipitated unchanged from solution in alkali even after long heating. The authors have prepared dibenzenesulphohydroxamic acid which they find to melt a t 126O although Koenigs (Abstr.1878 573) and Piloty (Zoc. cit.) gave the melting point 109'. With alkalis this acid yields benzenesulphinic acid and nitrous acid whilst with sulph uric acid it gives hydroxylamine. The corresponding naph- thalene derivative OH*N(S02*C10H7a)2 when treated with alkalis likewise gives nitrous acid and a sulphinic acid the latter being however the p compound namely P-naphthalenesulphinic acid ; if now the liquid be acidified the latter acid reacts with the nitrous acid giving di-P-naphthalenesulphohydroxamic acid OH*N(S02~CloH,~),. The nitrous acid formed in this alkaline hydrolysis is obtained by the splitting off of water from the radicle N(OH) so that in this case as also in those given above each sulphonic group attached to the nitrogen atom is ieplaced by a hydroxyl group.This also happens in the alkaline hydrolysis of tribenzenesulpho- hydroxylamine (Ph*SO,),NO in which nitric acid is formed. The analogy existing between the behaviour of these various compounds on alkaline hydrolysis is shown by the following scheme (ClOH7*SO2)HN*OH + (OH)HN*OH -+ NOH (C,oH~*SO,),N*OH -+ (OH),N.OH -+ NO,H (Cl,M7-S0,),N0 -+ (OH),NO -+ NO,H T.

It is only slowly attacked even by conceutrated aqueous potash whilst acids convert it into a resinous mass. o-Nitrosophenol (0-quinoneoxime) can be prepared from o-nitroso- anisole by gradually adding a n aqueous solution of the latter to boil- ing aqueous potassium hydrogen sulphate. The free nitrosophenol has hitherto only been obtained as an oil.The sodium salt crystallises in dark red plates with a green surface lustre and decomposes explosively when heated. The barium salt is sparingly soluble in water; the .ORGANIC CILEMISTRY. 767 silvei- salt is a heavy microcryst alline almost black precipitate which decomposes explosively when heated or brought into contact with a drop of sulphuric acid or fuming nitric acid.

The hydrochloride acetyl and benxoyl derivatives of the latter compound crystallise in white needles and melt respectively at 227-230' 136' and 151-152'; the amine reduces platinic chloride and hence the double salt was not obtained. 2 6-Biaminothy~nyl ethyl ether hydrochloride OEt*C,HMePd( NH,HCl) resulting from the complete reduction of the corresponding dinitro- compound separates from a mixture of concentrated hydrochloric acid alcohol and ether as a snow-white powder decomposing at 215' ; the tetya-ucetyl derivative crystallises from dilute alcohol in white flakes melting at 146'.By W.

By ADOLF VON BAEYER and VICTOR VILLIGER (Ber. 1902 35 3013-3033. Com- pare this vol. i 380).-Trianisylmethane does not as was a t first believed form coloured salts and hence this substance like triphenyl- methane is not halochromic and the distinction between ammonium and oxonium salts which was founded on the apparent halochromism of these substances,.cannot therefore be maintained The properties of triphenylcarbinol in many re-spects differ from those of both alcohols and acids and are more closely allied to those of aldehydes or ketones.A close analogy exists between the behaviour of the carbinol to many reagents and that of nitrous acid. The carbinol slowly combines with sodium hydrogen sulphite to form sodium triphenylmethylsulphonate CPb3*S03Na 2H,O which crystallises in large lustrous plates. The free acid crystallises in sparingly solu- ble needles. When the carbinol is heated with aniline and acetic acid the anilide which has been previously prepared from aniline and triphenylbromomethane is formed. Phenylhydrazine yields with the carbinol a substance which melts a t 108.5O and is probably identical with the triphenylmethylazobenzene obtained by Gomberg from tri- phenylbromomethane.The carbinol also reacts readily with hydroxyl- amine yielding a product C38H3202N melting a t 182-184" but the constitution of this substance has not been ascertained. Triphenyl- carbinol readily combines with phenol forming hydroxytetraphenyl- methane CPh3-C6H,*OH which crystallises in needles or plates and melts a t 2829 This substance behaves as a phenol and yields a potassium salt which is readily soluble in alcohol. Friphenyl-p-anisyl- methane is formed from the carbinol and anisole and crystallises in needles melting a t 194'. These reactions with sodium hydrogen sulphite aniline and phenol correspond with the reactions of nitrous acid with the same types of compounds and the analogy is also supported by the ready esterification of the carbinol by alcohols its770 ABSTRACTS OF CHEMICAL PAPERS.union with sulphuric acid and the fortnation of double salts of tri- phenylchloromethane and metallic chlorides. The basicity of a number of methoxyl derivatives of benzglidene- acetone &pd triphenylcarbinol was measured by ascertaining how much dilute alcohol was required to hydrolyse and thus decolorise solutions of molecular proportions of the various substances in a standard solu- tion.of acetic and sulphuric acids. Taking the basicity of dibenzyl- ideneacetone as 1 those of the methoxyl derivatives are as follows mono-pcompound 3.9 ; pp-compopnd 13.5 ; 00-compound 3-7 ; mm-com- pound 1.2. Similarly taking the basicity of triphenylcarbinol as 1 we have mono-p-compound 6.3 ; di-p-compound 34; tri-p-compound 286 ; tri-o-cornpound 7.6 ; tri-m-compound 1.7 ; oop-compound 27.3.I n both cases the effect of the methoxyl group is greatest in the para-position whilst a greater effect is produced by its introduction into triphenyl- carbinol than into dibenzylideoeacetone. Comparing the effect of the introduction of the group in the same position into successive rings i t is found that the basicity increases in geometrical ratio and this leads to the important conclusion that the three phenyl groups of the carbinol have an equal influence on the basicity of the derivatives so that it becomes improbable that the formation of coloured salts can be referred to the presence of a quinonoid group in which only one phenyl group is concerned.The increased basicity produced by the introduction of the methoxpl groups is accompanied by an increase in the chemical activity of the hydroxyl group of triphenylcarbinol. Tri-p-anisylcarbinol is much more easily reduced than triphenylcarbinol and also unites with sodium hydrogen sulphite much more rapidly the reaction taking place at once whilst in the case of the triphenyl-derivative it requires weeks for its completion. The sodium salt produced crystallisss in large colourless plates and has the formula C( C,H,*OMe)3*S03Na,$H,0. Trip-anisylcarbinol is at once acted on by hydrocyanic acid forming tri-p-anisylacetonitrile which crystallises in long rectangular plates and melts at 1285-129O. Triphenylacetonitrile has been prepared by heating triphenylchloromethane with mercuric cyanide.Tri-p-anisyl- carbinol also reacts readily with aniline forming a blue colouring matter. These facts further confirm the conclusion that the activity of the hydroxyl group is conditioned not by any one of the phenyl groups present in the molecule but by the nature of the whole complex with which t.he hydroxyl is united. The following new compounds have been prepared in the course of the work Benzylidene-p-ani8yylideneacetone (p-methoxydibenzylideneacetone) is obtained by the condensation of benzylideneacetone and p-anisalde- hyde and forms nodular crystals melting at 9 6 . 5 O .

Auto-oxidation of Pyrogallol. By CARL D. HARRIES (Ber. 1902 35 2954-2959).-When pyrogallol dissolved in barium hydr- oxide solution is shaken with air it undergoes oxidation forming a hexa- hydroxydiphenyl which probably has the constitution 3 4 5 3' 4' 5'.It crystallises from hot water in white needles which begin to decompose when heated to ZOO" dissolves in alkali hydroxides giving deep coloured solutions and reduces Pehling's solution but yields no quinone when treated with an alcoholic solution of iodine. The acetyl derivative crystallises in small colourless plates and melts at Alkaline solutions of the substance absorb oxygen but yield no trace of purpurogallin; it is therefore probable that for the formation of the latter by the auto-oxidation of pyrogallol (Berthelot Abstr. 1898 i 645) the presence of pyrogallol as well as the hexahydroxy- diphenyl is necessary.Halogen Derivatives of the Phloroglucinols. 111.

Compare Abstr. 1901 i 206).-The mono-methyl and mono-ethyl ethers of methylphloroglucinol prepared by etherification with alcohol and hydrogen chloride yield on further etherification two methyl- ethyl ethers which are isomeric and must therefore be alkylated in the oppositions. This supports the contention of Bosse (Abstr. 1901 i 207) that direct etherification of methylphloroglucinol takes place in the first instance in the p-position (compare Abstr. 1902 i 463). 1-Methylphloroglucinol 4-ethyl ether crystallises from benzene in colourless glistening needles melts a t 136-137' boils a t 195-200' under 13 mm.pressure and is easily soluble in alcohol or ether.

If 'on etherification of the mono-alkyl ethers with alcohol and hydrogen chloride the reaction be carried too far it results in a non- volatile product but by stopping it before it has completely reached this stage a mixture of the mono- and di-alkyl ethers is obtained by distillation.

Pyrodypnopinacolin C32H,20 crystallises from alcohol in colourless crystals melts at 166" and distils between 465' and 475'. Its solubilities in the following media at their boiling points and a t the ordinary temperature respectively are acetic acid 2.2 and 0.1 ; alcohol 2.2 and 0.3 ; ethyl acetate and acetone 10 and 1.3 per cent.; i t is also more soluble in hot than i n cold benzene. With acetic acid ethyl acetate benzene acetone and acetyl chloride 2 mols of the substance combine with 1 mol. of these solvents to form crystalline molecular compounds stable at 100-1 05' but which decompose a t 150-160°. The acetic acid additive product crystallises in colourless plates melts a t 162O and is employed as a convenient means of separating pyrodypnopinacolin from the bye-products of its preparation.

Constitution of a New o-Chlorodinitrobenzoic Acid and of 0-Chloro-sn-nitrobenzoic Acid. By ATTILIO PURGOTTI and A. CONTARDI (Gaxxetta 1902 32 i 526-537).-The authors have determined the constitutions of the two following acids The dinitro-o-chlorobenzoic acid described by Kalle (D.R.-P.106510) and melting at 199-200". This acid is best prepared by heating at 130-140" a mixture of o-chlorobenzoic acid sulphuric acid and fuming nitric acid in suitable proportions. It boils at 240-241° and at 253" decomposes and for the most part explodes ; it is slightly soluble in water but almost insoluble in the other solvents. Since when nitrated in the cold with a mixture of sul- phuric and nitric acids o-chlorobenzoic acid yields the nitro-o-chloro- benzoic acid melting at 165' described by Hubner (Abstr. 1884 599) and this at higher temperatures gives with the same nitrating mixture Kalle's acid the latter as well as Hiibner's acid must have a nitro- group in the 3- or 5-position. Further the dinitro-acid gives a n almost theoretical yield of the methyl ester in presence of hydrogen chloride and as position 2 is occupied by chlorine position 6 must according to778 ABSTRACTS OF CHEMICAL PAPERS Victor Meyer's rule be free.When heated with excess of ammonia solution the acid yields the dinitroaminobenzoic acid [XH 2N0 = 2 :3:51 which with dilute sodiym hydroxide solution gives the corre- sponding dinitrosalicylic acid hence Kalle's acid has the constitution [Cl NO NO = 2 3 51. . When boiled with excess of barium hydroxide solution i t yields o-p-dinitrophenol. The acid may also be prepared synthetically by heating m-dinitrosalicylic acid with phos- phorus pentachloride. The o-chloro-m-nitrobenzoic acid described by Hubner (loc. cit.) when boiled for some time with excess of concentrated potassium hydroxide solution yields the nitrosalicylic acid [CO,H OH NO = 1 2 51.The constitution of the acid must hence be CO,H C1 NO - 1 2 5. %:H.

Cluim. 1902 [iii] 27 875-S82).-By the action of ethyl trichloroacetate on benzene in presence of aluminium chloride the author has obtained fluorenecarboxylic acid which is sparingly soluble in the ordinary solvents ; the solutions are generally fluor- escent. If slowly heated the acid melts at 209-21Oo but if i t is first plunged into a bath heated t o 180" i t does not melt until 216-217O.It readily sublimes at 200' and undergoes decomposition a t 2S0-290° carbon dioxide being evolved and fluorene formed. The fluorene so obtained crystallises from alcohol in dazzlingly white pearly scales melts at 1 1 5 O and is quite unaltered by light. The acid obtained i n this manner agrees in properties with that obtained by Fried- lander (Abstr. 1877 492) but the ethyl ester obtained from i t is quite diflferent forming glassy crystals which melt at 60" and are very soluble in alcohol The above synthesis appears t o be a general one and applicable t o the formation of substituted fluorenes. A. F. Affinities of the Halogenated Hydroxybenzoic Acids in Relation t o their C o n s t i t u t i o n .By ANGELO COPPADORO (Guxxatta 1902 32 i 537-572).-The author has measured the affinities of a large number of derivatives of benzoic acid containing at the same time one or more halogens and hydroxyl groups. The entry of a hydroxyl group into benzoic acid in either the ortho- or meta-position produces a n increase in the affinity constaut whilst in the para-position a diminution takes place ; when other hydrbxyl groups now enter the molecule they produce in some cases a n increase in others a decrease in the affinity constant. Ostwald's method was used in the author's measurements the temperature employed being 25". The melting points of the acids exzmined are given in brackets. 5-Chlorosalicylic acid (172") is 1.9 times as strong as salicylic acid ; 3 5-dichlorosalicylic acid (219*5O) 2.4 times as strong as 5-chlorosali- cylic acid ; 5-chloro-2-ethoxybenzoic acid (21 So> 1.6 times as strong 3 i 2784 ABSTRACTS OF CHEMICAL PAPERB.as 2-methoxybenzoic acid ; and 3 5-dichloro-2-methoxybenzoic acid (166*5' 10 times as strong as 5-chloro-2-ethoxybenzoic acid. 2-Chloro 3-hydroxybenzoic acid (156-157') and 6-chloro-3-hydroxy- benxoic acid (178') have equal affinity constants which are almost the same as that of 6-chloro-3-methoxybenzoic acid (1 68-1690) ; 2 6-dichloro-3-hydroxybenzoic acid (122-124') has an affinity about 16 times as great as these. 2-Chloro-6- bromo-3-hydroxybenzoic acid (116-118') has almost the same affinity as 2 6-dichloro-3-hydroxy- benzoic acid which confirms the constitution given by Martini (this vol.i 150). Only about 1-1.5 per cent. of these acids are esteritied by Fischer and Speier's method (Abstr. 1896 i ZOl) whilst Martini's 6-chloro-2-bromo-3-hydroxybenzoic acid (1 94- 195') (Zoc. cit.) has an affinity 12 times as great as those of its two isomerides and can be esterified to the extent of more than 70 per cent. by either V. Meyer's or Fischer and Speier's method; hence the bromine atom cannot be in the position 2 but must be at either 4 or 5. 3-Chloro-4-hydroxybenzoic acid (169-170O) has an affinity constant about double t h a t of p-hydroxybenzoic acid ; this is about the same change as is produced when a chlorine atom enters in the meta-position to the carboxyl in either benzoic or salicylic acid. The two dichlaroprotocatechuic acids ( +.3H20 220') and (239') show when the dilution is great almost equal ailinities and these are about the same as that of dichloroveratric acid (182-183').The methyl (+ 1.$H20 193') and ethyl (+ 24H,O 155') esters of gallic acid have about equal dissociation constants greater than that of pyrogallol. The affinity of the methyl ester of monochlorogallic acid (+H,O 159-160') is about 2.6 times and that of the ethyl ester ( + H,O 106-107') about twice that of t,he corresponding gallic ester. The methyl (+ l$H,O 160-170') and ethyl (+ liH,O 151-153') dichlorogallates have respectively 2.4 and 2-33 times the affinities of the above corresponding monochloro-compounds ; methyl dibromogallate (+ l&H,O 169') gives still higher values for the affinity constant. The results obtained with ethyl dibromogallate (+1$H20 137') and methyl (+lhH,O 162-163') and ethyl ( + 1 .$H,O 134-135') chlorobromogallates were unsatisfactory. T.H. P. Reactions of Hydrocoumarone. By JOHAKNES BOES (Chem. Centr. 1902 ii 370 ; from Apoth.-Zeit. 17 422).-Hydrocoumarone dissolves in concentrated sulphuric acid forming a yellowish-red solution.

Direct Conversion of Cinnamic Acid into a-Truxillic Acid. By C. N. Rrmm (Bey. 1902 35 2908-2909).-Liebermann (Abstr. 1895 i 470) showed that cinnamylidenemalonic acid was converted under the influence of light into an isomeric acid which the author (this vol. i 617) has proved t o be a tetramethylene derivative ; on oxidation the latter yields a-truxillic acid Since both cinnamic and a-truxillic acids are found in the leaves of Erythroxylon coca it seemed possible that the action of light on the former gave rise to the forma- tion of the latter acid.Very finely powdered cinnamic acid was exposed t o light for three-and-a-half weeks during which however there were only 50 hours of bright sunshine. Seventy per cent. of the acid was found to have been changed into a-truxillic acid CI8Hl6O4 which crystallised in needles melting at 275' and yielded a methyl ester (m p. 173'). On distillation cinnamic acid is re-formed. K. J. P. 0. Dibromo-a-truxillic Acid. By R.

When the acid is dissolved in concen- trated sulphuric acid and the solution is poured into water cinnamyl- idenemalonic acid is precipitated. E. G. Study of Lichens. X. By WILHELM ZOPF (Annalen 1902 324 39-78. Compare Abstr. 1899 i 716).-The name proto- lichesteric acid is given to a colourless acidic substance obtained from Cetraria cucullata this lichen yielding 2.2 per cent. of the compound whilst C. chlorophylla furnishes only 0.5 per cent.; this acid can also be extracted from C .complicata and C. islandica provided that ether is employed and not alcohol the latter solvent causes the transformation of the subtance into its isomeride lichesteric acid (m. p. 124-125O); this cbange is also effected by hot acetic anhydride. Protolichesteric acid C,,H,,O crystallises from benzene light petroleum ether or alcohol in nacreous rhombic leaflets melting a t 103-104O. When separating slowly from dilute alcoholic solutions i t assumes the form of pyra- midal hernimorphous rbombic crystals having an extinction parallelORGANIC CHEMISTRY. 789 to the principal axis The acid has aD 12.1' a t 1 9 * 5 O it dissolves in sodium hydrogen carbonate solution and in the presence of alkalis immediately decolorises potassium permmngmate.Mineral acids re precipitate the unchanged substance from its solutions in the alkali hydroxides and although partly transformed into amorphous products protolichesteric acid is not converted into lichesteric acid when heated above its melting point. I n C. chlorophylla protolichesteric acid is accompanied by a small quantity of atranoric acid C. complicata also furnished protocetraric I-usnic and atranoric acids. The lichesteric acid isolated from C. isladdica by Schnedermann and Knop is in reality the product of the transformation of protolichesteric acid and when ether or benzene is employed in the extraction only the latter substance is obtained. The amorphous dilichesteric acid extracted from C. islandica var. vulgccris by Hesse is a decomposition product of protolichesteric acid formed by treating the latter substance with glacial acetic acid a t 80".C. tubulosa (C. juniperina var. tubulosa) yields usnic vulpic and pinastric acids the last being identical with the substance isolated from C. pinastri. I n addition to these compounds C. tubulosa furnishes a new substance cetrariulic acid which separates in lustrous pale olive- brown leaflets sparingly soluble in cold alcohol ether or benzene but dissolving more readily on warming. I n dilute potassium hydroxide solution the new acid dissolves with evolution of gas; it is also soluble in an aqueous solution of sodium hydrogen carbonate. Barbatic acid isolated from Usnea longissima (Abstr. 1898 i 99) forms a characteristic sodium salt which crystallises in rosettes of flattened curvilinear needles.U. cornuta yields d-usnic and usnaric acids the latter in larger quantity. U. ceyatina obtained from the pine trees of the Black Forest a t an altitude of 700-800 metres furnishes only barbatic acid and a trace of usnic acid ; this result is contrary to that of Hesse (Abstr. 1895 i 298) the latter observer stating that barbatin and a large quantity of usnic acid are obtainable from the lichen. U. dasypoga accompanies the preceding species and yields barbatic d-usnic and usnaric acids but not alectoric acid (compare Hesse Abstr.; 1900 i 149). Parmelia sinuosa contains dusnic acid and probably usnaric acid. Thamnolic acid a substance isolated from Tharnnolia uermicularis when heated a t 50-60' with concentrated hydrochloric acid yields thamnolin a reddish-brown microcrystalline substance dissolving in hot water alcohol chloroform or glacial acetic acid to a red solution.This product is also sparingly soluble in ether or benzene and develops a reddish-brown coloration with ammoniacal or alkaline solutions ; it is reprecipitated by hydrochloric acid but not by carbon dioxide. Cladina uncialis contains d-usnic and thamnolic acids the former being identified by conversion into usnolic acid and the latter by the thamnolin reaction. Squamatic acid hitherto only obtained by Hesse from Cladonia spuamsa has also been isolated from C'. glauca. The presence of patellaric acid in Urceolaria scruposa has been con- firmed; it crystallises from 50 per cent. alcohol in flattened plates and decomposes at 165'. This acid gives a bluish-red coloration with19 0 ABSTRACTS OF CHEMICAL PAPERS.bleaching powder and also develops an intense blue coloration with a solution of barium hydroxide or hydrated barium peroxide. Lecanoric acid has the same melting point and develops a similar coloration with bleaching powder but not with barium hydroxide or peroxide. Olivetoric acid develops a bluish-green coloration with the latter of these reagents but not with the former. Patellaric acid dissolves in sodium hydrogen carbonate and cold barium hydroxide solutions without decomposition and acids regenerate the unaltered substance ; when heated with dilute potassium hydroxide solution it develops a yellow coloration which then becomes red and on adding a few drops of chloroform the liquid acquires a deep green fluorescence which is rendered more distinct by cooling and diluting.Lecanoric and atranoric acids could not be detected in the extracts from U. scruposa. G. T. M. Reduction of Carboxylic Derivatives to Aldehydes and their Derivatives and to Amines. By FRANZ HENLE (Ber. 1902 35 3039-3044).-The hydrochlorides of the imino-ethers are readily reduced by sodium amalgam and dilute acids t o the corresponding aldehydes. If the redyction be carried on in presence of phenyl- hydrazine or semicarbazide the corresponding hydrazone or semicarb- azone is obtained. Benzimino-ethyl ether hydrochloride is readily converted in this way into benzaldehyde the yield amounting to 23.5 per cent. of the theoretical.In the presence of phenylhydrazine the yield of benzylidenehydrazone is quantitative and this reaction can readily be demonstrated a voluminous precipitate of the hydrazone being formed. I n the presence of semicarbazide a yield of 52 per cent. of the theoretical amount of semicarbazone is obtained. I n a similar manner acetimino-ethyl ether hydrochloride yields 40 per cent. of the theoretical amount of ethylidenephenylhydrazone. I n the absence of phenylhydrazine the chief reaction is the hydrolysis of the imino-ether but a certain amount of acetaldehyde is also produced. Since phenylhydrazones can be reduced to amines this reaction affords a new method of passing from the nitriles to the primary amines all the operations being carried out at low temperatures.Benzamidine hydrochloride is reduced by sodium amalgam and hydrochloric acid to benzylamine the yield amounting to 38 per cent. of the theoretical.

Chim. 1902 [iii] 27 888-892).-The crystals of the camphor compounds have a completely symmetrical form although in solution they are optically active. The author demonstrates in the case of benzylidenecamphor and p-bromobenzyl- idenecamphor that the corrosion figures obtained by means of benzene exhibit enantiomorphism. The author has also found that the enantio- morphic forms of benzylidenecamphor can give mixed crystals so that the crystals of the one form can induce the crystallisation of the other.The author puts forward the idea that; pseudo-racemism and even true racemism may be due entirely to the relative arrangement of the crystalline molecules of the oppositely active forms.

Compounds of the Thujone Series. By OTTO WALLACH (Annalen 1902 323 333-373. Com- pare Abstr. 1895 i 619; 1897 i 246).-isoThujone when oxidised with potassium permanganate solution gives rise to a ketolactone and two acids. The ketolactone ClOH,,O melts at 43-44' and yields a semi- curbaxone C,oH1,02:N*N H*CO*NH melting a t 188-189'.The oxime C,,H,,O,:NOH separates from dilute methyl alcohol in transparent prismatic crystals melting at 155-156' ; the phenyl- hydraxone forms snow-white crystals and melts at 144-146". The ketolactone is not identical with that obtained from thuja- menthone. The acidic products of the oxidation of isothujone are ketonic acids having the formulae C,H,,O and C,H,,O and are separated by the fractional crystallisation of their semicarbazones in alcohol. The semicarbazone of the former acid melts at 1S8-1S9°; and acid regenerated from this derivative melts at 73-74' boils at 145' under 10 mm. pressure and when oxidised with sodium hypobromite decom- poses into bromoform and isopropylsuccinic acid.This result indicates that the C acid is an isopropyllcevulic acid having one of the following forrnulz CH2Ac*CHPr@*C02H or CHAcPr@*CH2*C02H. This acid yields an-oxime CSHl3O2:NOH melting a t 119-120" and a phenylhydraxone melting a t 100-1 0 1 O . The other ketonic acid C,H,,O is a n odourless liquid boiling a t 158' under 11 mm. pressure ; its semicas.6nxone is readily soluble in hot alcohol and boils at 154-156' ; the oxime melts a t 77". On oxidationso2 ABSTRACTS OF CHEMICAL PAPERS with potassium hypobromite the ketonic acid yields a lactone and a dibasic acid melting at 106-1 08' which is probably isopropylsuccinic acid. The ketolactone when oxidised with permanganate nitric acid or sodium hypobromite gives rise t o a n acid CgHl4O4 which is isomeric with homoterpenylic acid and resembles this substance by crystallising with lH,O; it crystallises from dilute methyl alcohol in plates melt- ing at 52.5-535O and boils at 205-206' under 12 mm.pressure; its silver salt O,H,,O,Ag is soluble. When the oxidation is carried further by means of chromic acid the preceding acid yields isopropyl- lavulic acid. Benxylideneisothujone C,,H140 CHPh results from the interact ion of benzaldehyde and isothujone in the presence of a n alcoholic solution of sodium ethoxide ; i t boils at 210-212O under 12 mm. pressure and melts at 83'. Since isothujone can be ultimately oxidised t o an isopropyllaevulic acid its constitution must be represented either as according as to whether the isopropyl group in the oxidation product is in an a- or a P-position.Assuming that Wagner's rule for the oxidation of ethylene derivatives holds in this case the ketolactone must have one or other of the following formulae 111.

The condensation with benzaldehyde indicates that isothujono con- tains the residue CO*CH and accordingly formula I is to be preferred for the ketone.

The ketolactone closely resembles the corresponding sub- stance derived from isothujone and the two compounds yield semi- carbazones oximes and phenylhydrazones which are very similar.

Zeit. 1902,26,720-724). -Thujyl alcohol which is probably a dicyclic compound is converted by phosphorus pentachloride into an unstable thujyl chloride of in- constant composition (compare Semmler Abstr. 1893 i l?8) ; it con- sists mainly of a tertiary compound which with moist silver oxide gives a tertiary alcohol with bromine evolves hydrogen bromide and with alcoholic potassium hydroxide forms a *mixture of at least two hydrocarbons ; these in their properties resemble on the one hand dicyclic thujene (Tschugaeff Abstr. 1901 i 38) and the sabinenes and on the other monocyclic tanacetene (Semmler Zoc. cit.) and Wallach's thujene (Abstr. 1893 i 105).From the hydrocarbon frac- tion (b. p. 160-175') dipentene dihydrochloride can be obtained by treatment with hydrochloric acid. Thujyl chloride and hydrogen chloride yield two hydrochlorides one of which is dipentene dihydro- chloride. Thujone does not form an additive product with hydrogen chloride but with hydrogen bromide gives a substance which boils a t 105-117° under 11 mm. pressure ; by moist silver oxide it is con- verted into a n optically inactive ketonic alcohol which boils at 229-231' under the ordinary pressure and a t 105-106° under 11 mm. pressure and has a sp. gr. 0.9314 a t ZOO and m 1,4841 ; its oxime melts at 11 4.5-1 15'. By prolonged treatment or by warming with hydrochloric acid thujyl chloride is converted into a dichloride which boils a t 116-130' utlder 12 mm.pressure and is heavier than water; it is perhaps identical with the dichloride of dihydrocarveol. ThujgZ bromide is prepared by the action of hydrogen bromide on thujyl alcohol ; it boils a t 110-117' under 11 mm. pressure and has a sp. gr. 1.007 a t 20' and [aID + 23'5' ; it appears to be a secondary compound. The author believes that thujone is best repreeented by the formula CMe2<(5H.CH2.(30 * K. J. P. 0. By FRANK D. DODGE (J. Amer. Chern.

The first formuIa represents camphene as a saturated substance which is in harmony with its behaviour to bromine and permanganate. It affords further an explanation of the formation of isobornyl acetate by the opening of the 4-carbon ring; the position of the latter however precludes any further rearrangement of the rest of the molecule such as occurs in the corresponding reaction with pinene and so accounts for the possi- bili ty of reobtaining camphene from isoborneol.Whilst the new formula is in agreement with the constitution assigned to camphoric acid camphenylic acid and camphene glycol it is not in harmony with Jagelki's formula for camphenilone (Abstr. 1900 i 627). This since it assumes the presence of an oxidised 4-carbon ring is improbable and it is proposed to substitute for it the following formula /CH2*CJ32\ CMe-CHMe-TCH \CO-UH2/ representing camphenilone as a true lower homologue of camphor and satisfactorily accounting for its principal reactions.If the presence of a 4-carbon ring in camphene be admitted the symmetry of the camphor molecule suggests the possible occurrence of such 4-carbon rings in other positions and the reactions of camphenone would be satisfactorily accounted for by the following formula CH-C(C)H,)Me-CMe whilst fenchene which reacts like pinene and camphene with acetic acid would be represented thus CH-C(~H,)Me-CH.

Soluble Hydroxyanthraquinone-glucoside contained in Bar- badoes Aloes. By EUGEN AWENG (Chem. Cvntr. 1902 ii 368-369 ; from Apoth.-Zeit. 17 432).-A large quantity of a double glucoside which resembles that contained in Frangula and Xagrada (Abstr. 1901 i 39) has been isolated from the aqueous extract of Barbadoes aloes. This compound gives the reactions of hydroxyanthraquinone and when boiled with hydrochloric acid forms sugar and a substance similar to the $-emodin obtained from Franguln. A considerable quantity of $-emodin may also be extracted from the aloes by treating the portion insoluble in water with 95 per cent. alcohol. By the action of bromine or by boiling this $-emodin with alcohol and acid for a long time emodin and a compound which gives the reactions of rhamnetin are formed.By FRIEDR~CH KRAFT (C'hem.

Flavaspidic acid may be extracted from crude filicic acid by means of carbon disulphide; it dissolves in 30 parts of hot disulphide and on cooling 85 per cent. crystallises out. Flavaspidin resembles flavaspidic acid very closely and a small quantity is generally contained in the acid. It is however less soluble in carbon disulphide than the acid crystallises from ethyl acetate in colourless prisms melts at 199O and is readily soluble in benzene chloroform acetone or amyl alcohol; it dissolves in alkalis and decomposes carbonates of alkalis or alkaline earths.Filicinigrins consist of decomposition products of the other six components of the extract and form a brown to black amorphous powder ; they are distinguished from the other acids by their insolubility in light petroleum and their physiological inactivity ; their solubility is variable and sometimes the powder is infusible. The chief componeDtof the extractis the amorphous acid andon this its pharmacological effect depends. It forms a brownish-yellow amorphous powder melts at about 6OC is very readily soluble in acetone chloroform ethyl acetate ether benzene carbon disulphide carbon tetrachloride or glacial acetic acid.The slight reduction effected by boiling the acid with ammoniacal silver solutions or with Fehling's solution is probably due to the presence of decomposition products. Ferric chloride pre- cipitates an amorphous reddish-brown substance from the akoholic solution. When melted with alkalis the acid yields the same products as filicic acid (Boehm) together with methylphloroglucinol methyl ether melting a t 118-119" and an acid melting at 137". The amorphous acid must therefore possess a more complicated structure than filicic acid and may possibly be a homologue containing four butanone rings. Reduction of Artemisin by means of Stannous Chloride. By P.BERTOLO ,(Atti R. Accad. Lincei 1902 [v] 11 i 486-492. Compare Abstr. 1901 i 718).-1n order further to study the analogy 3. w. w. Extractum Filicis. E. W. W.ORGANlC CHEMISTRY 81 5 in behaviour existing between santonin and artemisin the author has investigated the reduction of the latter by means of stannous chloride in hydrochloric acid solution. Instead however of yielding a compound analogous with santonous acid this reduction furnishes a product possessing a lactonic structure and having the composition C15H180 the same as that of santonin. This compound crystallises from alcohol or acetic acid in small white needles which melt at 269-270' and are slightly soluble in ebher chloroform benzene or aqueous alkalis; when suspended in water and treated with ferric chloride or sulphuric acid it is turned brown but remains undissolved.On boiling with solutions of the alkalis or alkaline earths the compound yields salts of a monobasic hydroxy-acid ; the barium (C,,H,,O,),Ba silver lead and copper salts were prepared ; when treated with hydrochloric or sulphuric acid these salts are slowly converted into the original lactonic compound The acetyl derivative of the latter C15Hlt03Ac crystallises from alcohol or from a mixture of chloroform or benzene with light petroleum in white shining leaflets or needles which melt at 205-206'; on boiling with potassium hydroxide solution and acidifying with hydrochloric acid the original lactone is re-formed. These results show that in place of the carbonyl group present in artemisin the reduction product of the latter contains a hydroxyl group of a phenolic nature.When fused with alkali the compound yields 1 4-dimethyl-p-naphthol ; this compound is not obtained either from santonin or artemisin and the author concludes that the ketonic groups in the molecules of these two substances occupy corresponding positions. On reducing artemisin by means of zinc dust and acetic acid a dextrorotatory compound of a lactonic nature melting a t 275' is obtained. When artemisin is treated with sodium carbonate and the solution acidified with dilute sulphuric acid a compound is obtained crystal- lising from water in long silky needles which melt at 121-122' and in alcoholic solution are dextrorotatory .

Similar results were obtained with various acid colouring matters. Experiments were also carried out on the extraction of picric acid both in neutral and in acid solution by silk amyl alcohol and toluene when it was found that the amount of picric acid extracted was much greater in acid solution than in neutral This the author explains by the diminution of the dissociation of picric acid by the acid added.R.

Compare this vol. i 51).-Freshly pre- pared hyoscine hydrobromide has [.ID - 27.7" at 15' ; after four weeks the rotation has diminished to [..ID - 25.9".This is probably due to the existence of a labile modification of hyoscine. The latter is obtained on separation of the alkaloid from its salts or from the crystalline form when placed over concentrated sulphuric mid or phosphoric acid. Atroscine monohydrate and dihydrate crystallise together on addition of a crystal of each to the syrupy atroscine at 5-So. At 0" the dihydrate at 15-20' the monohydrate is formed. I n presence of a trace of the monohydrate at 20" the dihydrate changes slowly t o the monohydrate; the change takes place more quickly iu contact with ether a t 15". When pure the dihydrate is not less stable than the monohydrate (compare Gadamer this vol. i 173 ; Kunz-Krause this vol.i 174).

Com- pare AnnuZen 1886,236 296).-Pyrrole derivatives have hitherto been obtained from three different isonitroso-derivatives by reduction in presence of a ketone or ketonic ester and the reaction has now been extended t o four additional isonitroso-compounds. The intermediate formation of amino-ketones is rendered probable by the fact that in many cases the substitution of aminoacetophenone for isonitrosoaceto- phenone was accompanied by a considerable increase in the yield whilst in certain cases pyrrole derivatives were obtained from tho amino-ketone but not from the isonitroso-ketone I n the new series of syntheses the following results were obtained.isoNitrosoacetophenone yields pyrrole derivatives with ethyl acetoacetate (the yield being 56 per cent.) acetylacetone (40 per cent.) ethyl acetonedicarboxylate ( 3 per cent.) benzoylacetone (4.5 per cent.) but does not yield them with ethyl oxalacetate ethyl acetoneoxalate dibenzoylmethane formyl- acetone phenylacetone diphenylacetone or acetophenone. Amino- acetophenone gives pyrrole derivatives with ethyl acetoacetate (almost 100 per cent.) acetylacetone (100 per cent.) ethyl acetone- dicarboxylate ( 9 per cent.) benzoylacetone (38 per cent.) and in traces with ethyl acetoneoxalate formylacetone and phenylacetone whilst i t does not yield them with ethyl oxalacetate dibenzoylmethane benzoylaldehyde diphenylacetone and deoxybenzoin.isoNitrosodeoxybenzoin yields pyrrole derivatives with ethyl aceto- acetate (25 per cent.) and with acetylacetone (50 per cent.) but not with deoxybenzoin. isoNitrosoacetone yields pyrrole derivatives with ethyl acetoacetate (50 per cent.) acetylacetone (33 per cent.) and in traces with benzoyl- acetone. Finally dimethyl isonitrosoacetonedicarboxylate yields ;t pyrrole derivative with dimethyl acetonedicarboxylate.

By ROBERT BEHREND and RICHARD THURW (AnnuZen 1902 323 160-178.Compare Abstr. 1900 i 63).-The dimethyluracils are most conveniently prepared by methylating 4-methyluracil with less than the calculated quantities of methyl iodide and potassium hydroxide ; under these conditions the mixture of di- methyl derivatives contains 60 per cent. of the @compound and 40 per cent. of the a-isomeride the formation of trimethyluracil being reduced to a minimum. Both these compounds on further methylation yield the same tri- methyl derivative namely 1 3 4-trimethylurucil ; this compound separates in rhombic crystals' melting at 110-112' ; like the mono- methyl compound it may be sublimed without decomposition. The two dimethyl derivatives on oxidation give rise to the same methyloxaluric acid the products of the two reactions being shown to be crystsllographically identical.The following results indicate that a-dimethyluracil is 3 4-dimethyl-2 6-dioxypyrimidine whilst i t s p-iso- meride is 1 4-dimethyl-2 6-dioxypyrimidine. 3 4-Dimethyl-1-eth~turacil (3 4-dimethyZ-1-ethyl-2 6-dioxypyrimidine T.

T. M.834 ABSTRACTS OF CHEMICAL PAPERS. Oxidation of Methyluracil. By ROBERT BEHREND and RICHARD GRUNEWALD (Annulen 1902 323 178-204. Compare preceding abstract).-When methyluracil is oxidised with an amount of potassium permanganate equivalent to three atoms of oxygen acetylcarbamide and oxaluric acid are produced the relative proportion of these sub- stances depending on the temperature; in the cold the former com- pound is the chief product at the boiling point the latter predominates whilst the two are formed in approximately equal amounts at 40-50". This result is obtained however only in alkaline solutions ; if the mixture becomes neutral or acid the proportion of acetylcarbamide increases and predominates even at high temperatures. 3-lIydroxy-4-nzet?tylurucil NH<Eg3%2>CMe is produced when 4-methyluracil is oxidised with one atomic proportion of oxygen by means of permaoganate solution the maximum yield being obtained at 20-40° when the solution is rendered neutral by the addition of an equivalent amount of acetic acid. The substance is sparingly solu- ble in water or alcohol but readily dissolves in alkaline or ammoniacal solutions ; it forms prismatic anisotropic crystals having either pyramidal or truncated ends ; with neutral ferric chloride i t develops a n intense blue coloration which disappears after a time or more rapidly on warming or treating with acids or alkalis.The compound was not obtained in a state of purity the percentage of carbon being somewhat too high. 3-Acetoxy-4-methyZuraciZ produced by treating the preceding sub- stance with acetic anhydcide crystallises from water in felted needles decomposing at 238-241° ; i t regenerates the hydroxy-compound by alkaline hydrolysis. 3-Hydroxy-4-methyluracil on further oxidation gives rise to acetylcarbamide and oxaluric acid. Although a compound intermediate between 3-hydroxy-4-methyl- uracil and its oxidation products could not be isolated yet the soluble product obtained by treating 3 3-dibromo-4-hydroxy-4-rnethylnracil NH<CO*CBr CO-K~>CIMe*OH with potassium hydroxide solution appears t o contain such a substance namely 3 3 4-trihydroxy-4- CO*C(OH) > met?~yEdi?~ydrouraciZ NH<Co-N$ ;' CMe*OH for on reduction it yields 3-hydroxy-4-methyluraci1 whilst on oxidation acetylcsrbamide and oxaluric acid are produced.Acetylallanturic acid is probably an intermediate product of the latter process b u t it has not been isolated.

The antidiazo-hydrates which are all white when treated with hydrochloric acid yield diazonium salts but the nitrosoamines yield hydrochlorides of the type NO*NHR,HCI. A further difference is shown by the rate of coupling as the antidiazohydrates couple much quicker than do the nitrosoamines.

The oxygen-free reduction products have been proved to be hydrazidines (amidrazones) and the constitutions of the compounds previously described are CsH11N3 phenylethenyl- hydrazidine NHPh*NH*CMe:NH (Abstr.1899 i 958) ; C,H,,N,,ORGANIC CHEMISTRY. 845 phenylmethylethenylhydrazidine (ibid.); and C,H,oN,Cll p-chloro- phenylethenylhydrazidine. Fhenylethenylhydruxidine hydrochloride NHPh*NH*CMe:NH,HCl or NHPh*N:CMe*NH,,HCl is obtained by the action of phenyl- hydrazine on acetimino-ethyl ether in ethereal solution ; hydrochloric acid is then added and the ether evaporated. The azidine hydro- chloride is separated from the unattacked phenylhydrazine by means of alcohol. It forms silky needles which contain $H,O. The hydrated salt melts a t 140' then loses water and resolidifies after which it melts at 205O. When a mixture in molecular proportion of this salt and hydroxylamine hydrochloride is left in concentrated aqueous solution with double the molecular quantity of potassium carbonate slender orange needles of phenykccxoucetccldoxime separate Phenyl hydrazoacetaldoxime when boiled with alcohol to which water has been added gives after the addition of hydrochloric acid ethengl- phenylhydraxidine hydrochloride.J.

Meg*CO CO2H*CH2*CH,*C*CO When oxidised it yields succinic acid and when reduced by means of hydrogen iodide a mixture of two isomeric '' hcemotricurboxylicc " ucids having the constitution of pentane-ay8-tricarboxylic acids.These were separated by crystallisation from water ; the more soluble (1 in 7.3 parts of water a t 10') melts a t 140-141' and the other (1 in 75 parts of water at 10') at 175-176' the isomeride with the lower melting p i n t is converted into the other form by heating either alone or with water or with hydrochloric acid a t 200". The electrical con- ductivities of both acids are far less than the conductivities of tricarb- allylic acids as determined by Zelinsky (Abstr. 1896 i 349). The isomeride of higher melting point was also obtained from the imide C8H90,N previously described (Zoc. cit.). Acetylhzmin and /3-hzemin when treated with aniline yield two amorphous products hmneins which have the empirical formuh C3,H,,04N4Fe and C3,H3!04N4Fe respectively.Experiments are described which tend to show that the oxidation with chromic acid of the hzemopyrrole described by Nencki and Zaleski (Abstr. 1901 i 434) yields the anhydride of methyl-n-propyl- maleic acid. R. H. P. Lacto-serum. By ERNST FULD (Beitr. chena. Physiol. Path. 1902 2 425-429).-Lacto-serum (Bordet) is obtained by immunising animals (rabbits in the present research) with milk ; their serum $hen causes a precipitate when added to milk. The reaction is a precipitation of the caseinogen but the presence of calcium salts is essential although they may be replaced imperfectly by barium salts. The other proteids are not involved. If the original immunisation is produced with cow's milk i t is only cow's milk or its caseinogen which gives the reaction; goat's milk is easily precipitable with VOL.LXXXII i. 3 9%846 ABSTRACTS OF CHEMICAL PAPERS rennet but not by this lacto-serum; human caseinogen gives scarcely any reaction. A given quantity of lacto-serum can only precipitate a certain quantity of caseinogen. The product has not the same insolubility in salt solution that casein has. Digestion of lacto-serum with a third of its volume of horse-serum has no influence. W. D. H. Specific Precipitins. By PHILLIPPE EISENBERG (Bull. Acad. Xci. Cracow 1902 289-310).-The experiments were performed by immunising rabbits against egg-albumin and horse-serum. A sug- gestion for quantitative work on the ‘ precipitins ’ obtained is to take measured quantities of the serum diluted so that i t only just gives the reaction The amount of precipitin ‘ absorbed ’ means that which takes part in the process of precipitation.The ‘precipitin’ has many of the characters of coagulated albumin and contains both precipitin and ‘precipitable substance,’ but not all of either. An excess of both is present which can be detected by a further precipi- tate occurring when more of either substance is added. Excess of ‘ precipitable substance ’ inhibits precipitation ; this is attributed to an inhibitory substance in the ‘ precipitin.’ All immune substances are not contained in the pseudo-globulin fraction but were found also in the eu-globulin fraction of the serum W. D H. Action of Superheated Steam on Keratin. By RICHARD BAUER (Zeit. physiol. Chem. 1902 35 343-357. Compare Kruken- berg Sitxungsber.Jena Ges. Naturwiss. 1886).-When keratin obtained from horn shavings is heated with water in sealed tubes a t 150° for 24 hours considerable amounts of hydrogen sulphide and a second volatile sulphur compound presumably methyl mercaptan are formed. The solution contains two compoulrds corresponding with Neumeister’s atmidalbumin and atmidalbumose which the author terms atrnidkemtin and cctmidkeratose. They are most readily obtained by concentrating the solution and saturating i t with powdered sodium chloride when atmid keratin is precipitated. The filtrate from this precipitate on treatment with hydrochloric acid saturated with sodium chloride yields first a mixture of the two compounds and then atmidkeratose. The compounds are only slowly acted on by pepsin and trypsin.J. J. S. Glutinpeptone. By W. FAHRION (Chem. Zeit. 1902,26,675-677). -Glutinpeptone obtained by warming animal hide or gelatin with alcoholic sodium hydroxide is strongly basic. Unlike its hydro- chloride it is insoluble. in alcohol. The saponification number increases with the duration of warming with alkali; the increase is more rapid in aqueous solution than in aqueous-alcoholic solution. The saponifica- tion number is lower when air is completely excluded than when it has free access to the solution. From this behaviour it is concluded that glutinpeptone contains no alcoholic hydroxyl groups and that it is not an aldehyde ketone or lactone. A determination of the equivalent of uric acid showed that it increases in the same way as that of glutinpeptone ; from this it is assumed that the high value ofORGANIC CHEMISTRY.847 the saponification number of glutinpeptone on prolonged heating is due to the presence of imino-groups united to carbonyl groups. When glutinpeptone is oxidised in alkaline solution with potassium permanganate a substance is obt,ained which is insoluble in alcohol but which gives a soluble hydrochloride; a t the same time butyric acid is formed and a very small quantity of benzoic acid. Glut,inpeptone scarcely absorbs iodine indicating that i t does not contain doubly-linked carbon atoms in an open chain. J. McC. Nucleic Acid from Embryos of Wheat. By THOMAS B. OSBORNE and ISAAC F. HARRIS (Zeit. physiol. Chem. 1902 36 85-133. Compare Abstr. 1900 i 573),-The embryos of wheat contain relatively large amounts of a nucleic acid which the authors term triticonucleic acid.Some 3.5 per cent. of the acid is con- tained in the commercial flour freshly obtained from wheat embryos but the amount rapidly diminishes when the flour is kept. The acid has most of the properties characteristic of the nucleic acids of animal origin but is much less readily soluble in water. I t s per- centage composition agrees best with the formula C41HG,031N1SP4. It forms acid potassium sodium and ammonium salts which are soluble in water yielding solutions with strongly alkaline properties and it is found to be practically impossible to obtain the acid free from mineral matter. When hydrolysed with mineral acids triticonucleic acid yields guanine (1 mol.) adenine (1 mol.) uracil (2 mols.) and pentoses (3 mols.).The silver salt contains six atoms of silver and the free acid pre- sumably contains six hydroxyl groups. It is suggested that the acid is formed by the condensation of four P(OH) groups the four atoms of phosphorus being united with the aid of three oxygen atoms. When boiled for a short time with dilute acids only one-fourth of the total phosphorus is obtained in the form of orthophosphoric acid and a complex phosphorus acid is produced by the elimination of one atom of phosphorus together with guanine adenine and a molecule of pen tose. Triticonucleic acid may be identical with the nucleic acid obtained from yeast and somewhat resembles guanylic acid. alloOxyproteic Acid a Normal Constituent of Urine. By STANISLAUS BONDZY~~SKI and K.PANEK (Ber. 1902 35 2959-2963). -Analyses are given of the buriurn and silver salts of a new acid allooxyproteic acid which the authors have isolated from urine. The acid contains carbon hydrogen oxygen nitrogen and sulphur ap- pears to be a normal constituent of urine and is very similar to oxypro- teic acid (Abstr. 1898 i 501) ; it does not give the typical reacfiona of proteids and has not. yet been isolated in the pure state. J. J. S. R. H. P. Isolation of Malt Enzymes and the Proteolytic Enzyme of Malt By CARL J . LINTNER (Chem. Centr. 1902 ii 288-289 ; from Zeit. ges. Brazcw. 25 365-368).-The malt enzymes are best isolated848 ABSTRACTS OF CHEMICAL PAPERS. by salting out with ammonium sulphate. The small precipitate first obtained on addition of the sulphnte has a distinct diastatic but scarcely any proteolytic action ; the active enzyme is precipitated on further addition of the sulphate.The enzymes isolated by this means are capable of liquefying gelatin and have a diastatic action or fermentative power of 143 whilst that of the enzyme obtained by precipitation with alcohol seldom rises above 80. The experiments confirm the presence of a proteolytic enzyme in malt but do not indi- cate that i t plays any important part in the mashing process. The assumption that it resembles trypsin and determines the decomposition of proteids during germination is unfounded. When liquefied gelatin is digested with the enzymes for 48 hours a t 40° the glutin is scarcely attacked and only a very slight peptonisation could be detected by means of the biuret reaction The fermentative action of the enzymes should rather be compared with that of malt extracts which have been attenuated by heating and which although capable of liquefying starch paste are unable to convert the starch into sugar.E. W. W. Yeast-gum and Invertase. By KINTARO OSHIMA (Zeit. physio2. Chenz. 1902 36 42-48.

When the gum is hydrolysed with sulphuric acid the chief product is d-mannose. Attempts were made to purify crude invertase (Osborne Abstr.1899 i 967). If the extraction with chloroform a t 34' is continued for several days the yield of invertase is somewhat better but the product contains larger amounts of gum. A considerable amount of the gum is thrown down in the first fraction when the clear chloroform extract is fractionally precipitated with 93 per cent. alcohol. A simpler method for the removal of gum is t o precipitate the invertase from a neutral solution of Osborne's crude product with a 5 per cent solution of copper acetate t o wash thoroughly precipitate the copper as sulphide and t o pour the filtrate freed from hydrogen sulphide into alcohol. Invertase of Yeast. Quantitative Experiments on the Action of Alcohol and Acids on this Enzyme. By THOUAS BOKORNY (Crhem. Zeit.1902 26 701-703. Compare Abstr. 1901 ii 568)- The author's experiments demonstrate that the inverting action of yeast is not effected by the living protoplasm but by a material which can be separated from the yeast cell this view was originally expressed by Berthelot in 1860. Four grams of fresh yeast extract at 45-40' in 15 minutes can convert from 68 to 82 per cent. of a sucrose solution varying in strength from 5 to 20 per cent. When kept for several days under absolute alcohol at the ordinary temperature the inverting action of yeast is unimpaired but a t 45' it is completely destroyed. Similarly 5 per cent. formaldehyde has little effect at the J. J. 5. Dried yeast has in no way lost this power.ORGANIC CHEMISTRY. 849 ordinary temperature but destroys the inverting power at 45'.Dried yeast extract is changed but little as regards inverting power by keeping in 0.5 per cent. oxalic acid 0.5 per cent. hydrofluoric acid 2 per cent. acetic acid or 2 per cent. lactic acid.

The author also defends the views he has expressed previously on the constitution of the compounds obtained from aniline and mercuric acetate and other mercury aromatic compounds against Dimroth's criticisms. J. McC. [Formation of Aromatic Mercury Compounds.] By OTTO DIMROTH [and in part RICHARD METZGER] (Bey. 1902,35 263-3873. Compare Abstr.1899 i 154 428 and this vol. i 656).-The hydroxyphenylmercury salts (previously described) dissolve in dilute sodium hydroxide ; carbon dioxide precipitates from the solution of the ortho-compound the internal anhydride of o-hydroxyphenylmercury hydroxide C,H4<Hg ; from the para-compound a n oxide is obtained as a n insoluble white powder which cannot. be converted into o-phenylenemercury oxide. The pharmaceutical preparation Hydvarg yrum carbolicum which is prepared by heating sodium phenoxide and mercuric chloride in alcoholic solution and is generally considered to be a mercury phenoxide is now shown to consist mainly of a mixture of 0- and p-hydroxy- phenylmercury oxides and hydroxyphenylenedimercury oxide. o-Hercuryphenol (OH* C',H4),Hg is prepared by treating o-hydroxy- phenylmercuric chloride with sodium thiosulphate ; it crystallises in lustrous white plates which become coloured on heating and dissolve in alkali hydroxides but not in carbonates.The hydroxyphenyl- mercury salts give with nitrous acid at first coloured solutions and then coloured precipitates which resemble those obtained by the action of Millon's reagent on phenols proteids &c. p-Cresol and mercuric acetate i n mol. proportion give equal quantities of a mono- and a di-mercury compound; at loo' only the di- mercury compound is formed ; p-cresolmercury acetate OH* C$H3 Me Hg 0 Ac H20 is obtained by crystallising the product of the reaction from acetic acid ; i t decomposes at 200' ; addition of sodium chloride to the mother liquor precipitates p-cresolmercury chloride OH*C,H,Me*HgCl which crystallises in needles melting at 166' and decomposing a t 176' when it becomes solid.The corresponding iodide is prepared from the chloride and potassium iodide and crystallises in slender needles which begin t o decompose at 145'; the acetate prepared by dissolving the oxide in acetic acid crystallises -~ in leaflets melting and decomposing at 163'. The 0 ( OH*C,H *Hg),O oxide C6H,Me<yg is prepared as a white powder by dissolving 0850 ABSTRACTS OF CHEMICAL PAPERS. the chloride in dilute sodium hydroxide and then precipitating with carbon dioxide ; the sodium salt ONa*C,H,Me*Hg*OH crystallises in very soluble needles. The benxoyl derivative OBz*C6H,Me*HgCl prepared by the Schotten-Baumann method crystallises in slender needles melting a t 241-242'.o-lodo-p-cresol OH*C,H,MeI is prepared by the action of iodine on the iodide previously mentioned ; it crystallises in hair-like needles melting a t 35' and boiling a t 117' under 12 mm. pressure. Benzenediazonium chloride reacts with o-phenylmercury chloride forming the azo-compound N,Ph*C,H,(OH)*HgCl which is a reddish- brown powder melting a t 147'; it forms a stable additive product with 1 mol. of acetic acid which crystallises in yellowish-brown needles melting a t 126-128'; a hydrate with 1 or 1+H,O is obtained when water is added to the alcoholic solution and crystallises _in slender yellow needles which lose water when dried over sulphuric acid form- ing a very hygroscopic red powder; when dried a t loo' a red powder is obtained which is no longer hygroscopic.The azo-compound just mentioned combines with acids ; the compound with hydrogen chloride is a red powder melting a t 160'. When the azo-compound is boiled with hydrochloric acid i t is converted into p-hydroxyazobenzene. p-Hydroxyphenylmercury chloride and benzenediazonium chloride yield mainly p-hydroxyazobenzene together with a small quantity of a substancs probably benzeneazo-p-hydroxyphenylmercury chloride ; the latter melts a t 130-131" and forms a crystalline additive product with one mol. of acetic acid. Hydroxyphenyldimercury acetate and the diazonium chloride give chiefly benxeneaxo-o-hgdroxyphelzylmercury acetate ; i t crystallises in yellow prisms melting a t 197-198O; benxeneaxohyt.E1*oxyp~~enyldi~neri.cury chloride as an additive product with 1 mol. of acetic acid was also isolated by precipitating with sodium chloride and crystallising the product from acetic acid ; it melts and decomposes a t 165-1 70'. Berzxeneaxo-p-cresolmercury acetate N,Ph*C,H,Me(OH) *Hg*OAc forms red needles melting and decom- posing a t 269' ; the chloride prepared from the acetate crystallises in yellowish-brown silky needles melting and decomposing a t 249' ; both these compounds are soluble with difficulty in alkalis Thyrnolmercury chloride OH*C H,.MePr HgCl is prepared by adding sodium chloride to the acetic acid solution of the product of the reaction of mercuric acetake and thymol; it crystallises in needles melting at 139.5" ; the sodium salt forms needles ; thymoldimercury acetate OH*C6HMePr(Hg.0Ac) separates directly from the product of the reaction of thymol and mercuric acetate and forms needles melting and decomposing a t 215-216' ; the sodium salt crystallises in leaflets. A mixture of resorcinolmercury chloride and resorcinoldimercury chloride is obtained by adding sodium chloride to the product of the interaction of mercuric acetate and resorcinol ; chloroform extracts the monomercury compound C,H,( OH),*HgCI which crystallises in prisms containing chloroform and melts a t 105'; when free from chloroform it melts at 123' ; it is decomposed by water and yields a solution in sodium hydroxide rapidly becoming coloured. Resorcinol- climercury chloride forms an insoluble white powder which begins toORGANIC CHEMISTRY. 85 1 decompose at 200'. Quinol does not form a mercury compound but is oxidised t o quinhydrone by mercuric acetate. Phenol ethers such as anisole and phenetole react with mercuric acetate less readily than the phenols and yield substances which have previously been described. o-Benxophenonemercury chloride COPh*C,H,*HgCI is prepared by heating together dry mercuric acetate and excess of benzophenone converting the acetate thus formed into chloride by means of sodium chloride and separating the insoluble dimercury compound by ether ; the monomercury compound crystallises in leaflets melting a t 167-168' ; the dimei-cury compound is a yellowish powder. o-Belzxo- phenonenzercury . bromide melts at 1 7 6 O and .is converted by bromine into o-bromobenzophenone (m. p. 35'). Acetophenone and mercuric acetate yield phenacylmercury chloride COPh*CH,*HgCl the nucleus not being attacked; this substance forms needles melting at 145-1 4 6 O and is easily decomposed by bromine giving phenacyl bromide. Anhydrous mercuric benxoccte is obtained from the hydrated salt by crystallisation from chloroform ; i t forms crystals melting a t 165'; when co heated at 170° it is converted into a compound C,H4<Ha>0 which forms a powder soluble in alkali hydroxides and carbvonates and is changed by sodium chloride into chlorornerczcri6enxoic acid ; when treated with bromine o-bromobenzoic acid is formed. When dry mercuric salicylate is heated at loo' it is converted into salicylic acid and a compound OH*C,H,< >0 which is the anhy- dride of o-hydroxymercurisalicylic acid ; it is a white powder soluble in a1 kalis and identical with the pharmaceutical preparation Egdrargyrum salicylicum. By iodine it is converted into o-iodosalicylic acid con- sequently the mercury is attached to the benzene nucleus in the ortho- position relatively to the hydroxyl group. Mercuric Compounds from Terpineol and Dimethylheptenol. By JULIUS SAND and FRITZ SINGER (Ber. 1902 35 3170-3187).- Characteristic products cannot be obtained by shaking ethereal terpineol with aqueous mercuric nitrate or sulphate ; crystalline pro- ducts can however be obtained by dissolving yellow mercuric oxide in 20 per cent. nitric acid adding potassium hydroxide until basic nitrate begins t o separate and shaking with ethereal terpineol solu- tion the alkali and terpineol being added alternately until mercurous oxide begins t o be precipitated ; the solution is made strongly alkaline and on addition of potassium iodide gives an immediate precipitate of mercuricineol iodide a gradual separation of a-mercuric trans-terpin iodide from the filtrate and a further separation of p-mercuri-trans- terpin iodide on passing carbon dioxide into the solution. /CH,-CH Mercuricineol iodide CMe-0- CM&H crystallises from \CH( HgI)*CH,/ alcohol in small glistening prisms dissolves very readily in cold benzene or chloroform becomes yellow at 1 1 5 O and melts and decom- co Hg K.

The chloride crystallises from alcohol iu white felted needles melts constantly and sharply at 162' and unlike the iodide is readily soluble in alkali. The iodide does not yield a benzoate and when reduced with sodium amalgam does not yield a terpineol but a mobile oil which gives precipitates with hydrogen chloride bromide and ferrocyanide and is therefore in all proba- bility cineol. a-Mercuri-trans-terwin iodide separates from benzene in glistening colourless prisms is sensitive t o light becomes red at 120° and melts and decomposes a t 144'. It combines with alcohol to form the alcoholate CloHIQO,IHg,C,H,O which crystallises from alcohol in glistening needles and becomes red and melts a t 123-125'. The iodide is reduced by sodium amalgam or by electrolysis at a platinum cathode t o trans-terpin (m. p. 156'). P-~ercuri-trans-teipi~ iodide melts at 3S0 separates from. organic solvents as a n oil and like the preceding compound is reduced by sodium amalgam to trans-terpin ; when boiled with organic solvents it is readily converted into the stable a-compound. The a- and p-com- pounds are probably stereoisomerides differing only in the position of the -Hgl group ; as the a-compound is readily reconverted into terpineol by mineral acids it probably has the -HgI group in the cis-position relatively to the adjacent hydroxyl whilst the P-compound which is only slowly decomposed would have the -HgI in the ti-ans-position. Dimethylheptenol CMe,:CH*CH,*CH,*CMe,*OH prepared by Grig- nard's method from methylheptenone and magnesium methiodide is a highly refractive oil and boils a t 85-86' under 14 mm. pressure (uncorr.). Towards mercury salts it behaves in just the same way as terpineol giving an iodide C,H,,OIHg which is insoluble in alkalis and probably has the structure CMe,<o CMe >CH together with an iodide C,H,,O,IHg probably OH*CMe,*CH( HgI)*CH,*CH,*CMe,-OH soluble in alkalis which separates from benzene in glistening crystals becomes yellow and melts at 124-125' and probably also an isomeric oily iodide C,H,,O,THg.
