i. 1280 ABSTRACTS OF CHEMICAL PAPERS. Chemistry of Vegetable Physiology and Agriculture. The Fermentation of Pyruvie Acid by Bacteria. LASZL~ KARCZAG and L. M~CZLR (Biochem. &its& 191 3 55 7 0 - 87). -The bacteria which are capable of fermenting dextrose with evolution of gas are also able t o ferment pyruvic acid. Amongst such bacteria are B. coli 8. parnfyphi-B. and Gaertner’s bacillus. The gas evolution with bacteria follows more rapidly than with yeast but there is a marked difference between the two classes of fermentations for whereas with yeast the gas evolved is carbon dioxide the pyruvic acid yielding this gas and formaldehyde the gas evolved by bacteria consists for the most part of hydrogen. Formation of Hydrogen Cyanide from Proteins. R. W. EMERSON HAMILTON P.CADY and E. H. S. BITLEY ( J . Bio!. Chem. 1913 15 415-418).-Certain micro-organisms (B. pyocyanezcs) evolve hydrogen cyanide when grown on protein media especially if the medium is slightly acid t o litmus and phenolphthalein. This is absent when free mineral acid is present. Formation of Hydrogen Cyanide from Proteins. B. J. CLAWSON and C. C. YOUNG (J. Biol. Chem. 1913 15 419-422).- B. pyocyaneus B. fluorescens B. ciolncew and other bacteria the nature of which is still uncertain produce hydrogen cysnide from protein material. W. D. H. SAKAE TAMURA (Zeitsch. physiol. Ghent. 1913 87 85-1 14).-Chemical investigations were made on large S. B. S. W. D. H. Chemistry of Bacteria.VEGETABLE PHYSIOLOGY AND AGRICULTURE. i. 1281 quantities of the cells of Bacillus tubewulosis and Mycobacterium lacticola permgosum.Extraction with ether failed to give any phosphatides but treatment with warm alcohol showed the presence of a diaminomonophosphatide in each species of bacteria. Both cultures were found to contain an alcohol (C&H,,O) f o r which the name mycol is suggested. This alcchol is present in the bacterial cell partly as an ester of a higher fatty acid and it is t o the alcohol or its ester that the acid- and alkali-resistance and gram- positiveness of the organisms are due. Adenine and hypoxaiithine were present in each case in addition t o arginine histidine lysine phenylala.nine proline valine tyrosine and tryptophan. Bacterio- proteins are characterised by a high phenylalanine content. H. B. H. Fermentation of Cellulose by Thermophilic Bacteria.HANS YRINGSHEIM (Centr. Bakt. Yccr. 1913 ii 38 513-516).-Impure cultures of anaerobic thermophilic cellulose-decomposing bacteria were obtained from soil and horse manure. By means of a special apparatus the cultures were maintained a t 55-60° and samples of the decomposition gases were withdrawn from time t o time. These were found to consist of 22-49% carbon dioxide and the residue in all cases proved to be hydrogen. Examination of the residual liquid cultures showed the presence of formic and acetic acids but no butyric acid. This is significant as the latter is the chief product of anaerobic cellulose decom- positior at normal temperatures. Three grams of cellulose led to the production of 0.2125 gram of formic acid 1-15 gram of acetic acid a trace of lactic acid and a mixture of carbon dioxide and hydrogen in the above proportions.H. B. H. The Enrichment of the Invertase Content of Living Yeasts. LEOPOLD LICHTWITZ (Biochem. Zeitsch. 1913 56 160-162),-The author replies to certain criticisms of Meisenheimer Gambarjan and Semper (this vol. i 1139) who found that the invertase con- tent of yeast increases when the organism is kept in sugar solution. This is the direct contrary of what was found by the author. He calls attention to the fact however that yeast sown in large quantities in sugar solution as was done by Meisenheimer and his collaborators does not increase; on the contrary i t probably autolyses. This did not happen in the author’s own experiments; hence probably the difference in the results. Catalysts of Alcoholic Fermentation.HANS VON EULER (Zeitsch. physiol. Chem. 1913 87 142-144).-Earlier work has shown that the rapidity of fermentation by living yeasts is accelerated by the addition of alkali salts of organic and especially fatty acids and dried yeast or yeast juice is not affected in a similar manner. Of the two possible interpretations of the results particular attention has been paid to that which assumes that the activation is not directly connected with enzymes in the yeast cell and experiments have been made t.0 determine an alteration S. B. S.i. 1282 ABSTRACTS OF CHEMICAL PAPERS. of the protoplasmic layer of tlie cell or of the cell wall generally by the salts with adsorption and an alteration of surface tension.Preliminary experiments with sodium and ammonium salts of the acids having given negative results ail attempt was made to determine the action of various dye salts on the living cell,. According to their behaviour towards the yeast cell it was possible t o divide the dye salts into three classes namely those without action on the cell those which are clearly adsorbed and others the entrance of which into the cell depends on the fermentative activity of the lather. These phenomena and the part played by an altera- tion of the surface tension are being further investigated. H. B. H. Influence of Certain Inorganic Salts particularly Stannous Chloride and Bismuth Subnitrate on Fermentation. GILBERT GIMEL ( Bull. Assoc. china. Xuar. Dist. 19 13 3 1 128-1 29).-Reaults of further experiments confirm those obtained previously by the author (A.1909 ii 171). The activity of various yeasts in sweet worts is increased when the latter contain from 50 to 100 mg. of stannous chloride per litre. Bismuth subnitrate is soluble in acid liquids such as musts etc. and has a decided influence on the fermentation ; it appears to inhibit acetic fermentation. The use of pure yeast cultures and different conditions of fermentation are probably the reason of the opposite opinion arrived a t by Pozzi- Protein Degradation in Yeast. I. The Influence of Sugar Fermentation on the Protein Degradation of Yeast. W. ZALESKI and W. SCHATALOV (Biochem. Zeitsch. 1913 55 63-71).- Various views have been expressed to explain the fact that proteolysis is less in yeast that has been used for sugar fer- mentation than in unused yeast the Ivsnov has stated that acetaldehyde is the fermentation product which is responsible for the antiproteolytic action. This statement the authors have been unable t o confirm for they find that an appreciable inhibition of yeast autolysis only takes place in concentrations of this aldehyde which are far higher than those found in fermentation liquors. The same is alsol true for furfuraldehyde and for formaldehyde which latter however has a much stronger inhibitory action than acetaldehyde.Although the distillates from fermentations possess antiproteolytic properties the actual antiproteolytic substance has not been isolated. The conditions of nutrition of the yeast exert some action on the subsequent proteolysis.The addition of amino- acids to yeasts increases the autolytic degradation of their proteins ; it cannot be claimed however that they antagonise the antiproteo- lytic properties of the fermentation products. Biochemical Conversion of Betaine into Glycollic Acid. FELIX EHRLICH and FRITZ LANGE (By?*. 1913 46 2746-2752).-1n the course of their experiments on the behaviour of amino-acids towards micro-organisms the authors have examined betaine which is remarkably stable not only to concentrated sulphuric acid or Escot (this voll. i 1139). w. P. 8. S. B. S.VEGETABLE PHYSIOLOGY AND AGRICULTURE i. 1283 aqua regia a t high temperatures but also during passage through the bodies of most animals except the ruminants. They find that betaine is not assimilated by brewers’ and distillers’ yeasts o r by various kinds of Saccharomyces but is exkensively degraded by Willia aizomala Yichia farinosa Pichia membranefnciens and other yeasts rich in oxydases; also many moulds such as Penicillium Aspergillus Monilia Oidium and Dematium are able to employ betaine f o r the formation of their albumin.I n most cases charac- teristic degradation products of betaine cannot be isolated partly because the decomposition is too extensive partly owing t o the difficulty of separating the decompositlon products of the sugar added as a source of carbon. I n experiments on solutions con- taining betaine nutrient salts and ethyl alcohol as a source of carbon the authors find that aft8er the addition of a pure culture of Wi7Zia anomala and keeping for eight weeks glycollic acid is present in quantity sufficient f o r isolation; the amount is small because the acid is an intermsdiate not the final product of the assimilation-of the betaine.This is proved by the fact that TPiZlia anomala grows extensively in a solution containing nutrient salts and glycollic acid and carbamide as the only sources of carbon the g!ycollic acid disappearing completely after four months ; in a similar experiment in which carbainide is the only source of carbon growth of the yeast cannot be detected. I n the preceding experiments with betaine not a trace of tri- methylamine can be detected. Probably it is converted into methyl alcohol and ammonia the latter which also cannot be detected being utilised by the organism in the formation of albumin.I n conclusion the authors reply to Stoltzenberg (this vol. i 345; compare also Ehrlich A. 1912 i 835; Stoltzenberg ibid. i 680) concerning the isolation of betaine from molasses residue. c. s. Protein Synthesis in Plants. I. Protein Synthesis in the Bulbs of Allium cepe W. ZALESKI and W. SHATKIN (Biochem.. Zeilsch. 19 13 55 72-78).-Experiments confirm a former gtatement of Zaleski that the proteins increase in quantity in the injured bulbs when left in a moist atmosphere or in intact bulbs when allowed to grow in the dark. Estimations were of the total nitrogen proteins peptones ammonia acid amides organic bases and mono- amino-acids. It was found as a result that the proteins are formed at the expense of the monoamino-acids. The mono- and di-amino-acids and ammonia were also estimated in the various specimens after hydrolysis with acids.The results obtained indicate that the monoamino-acids pre-existing combine with the pre- existing proteins. There is no evidence that the acid amides without further change take any direct part in the protein synthesis. S. B. S. The Inulin Metabolism of Cichorium intybus (Chicory). 111. VIKTOR GRAFE and VALENTIN VOUK (Biochem. Zeitsch. 1913 56 249-257. Compare A. 1912 ii 977; this vol. i 148).-It is showni. 1284 ABSTRACTS OF CHEMICAL PAPERS that by the freezing of the roots the amount of inulin decreases whereas the amount of reducing sugar increases ; the amount of the latter returns to normal when the frozen roots are afterwards kept a t normal temperature whereas the amount of inulin remains unchanged.These results confirm the theory of Molisch that the dissolved inulin acts as a ‘‘ thermically active ” protector against cold. The changes in the inulin and reducing sugar distribution in the roots which had wintered iiz a normal manner were also investigated. It was found that a hydrolysis of inulin takes place before new parts of the plants are visible; the reserve substrances appear to be converted into building material and this allows the further hydrolysis of the inulin reserves. A resume of the results obtained by the authors up to the date of publication is also given. S. B. S. The Colorimetric Method for Determining Hydrocyanic Acid in Plants with Special Reference to Kafir Corn.C. K. FRANCIS and W. B. CONNELL (J. Ameq*. Chem. Soc.; 1913 35 1624-1628).,- After examining the various methods for the estimation of small quantities of hydrocyanic acid the authors decide in favour of a colorimetric process depending on the formation of ferric thiocyanate. This method indicates that Kafir corn contains minute quantities of combined hydrocyanic acid the quantity apparently being greater in frost-bitten or stunted plants than in normal ones. It is difficult to decide from the results whether the quantity of hydrocyanic present could prove fatal t o an animal fed with this mat er i a1 . D. F. T. Antitoxic Action of Chloral Hydrate on Copper Sulphate for Pisum sativurn. R. P. HIBBARD (Centr. Bakt. Pur. 1913 ii 38 302-308).-Water culture experiments in which garden peas were supplied with solutions of copper sulphate in concentrations varying from M3 x 10-4 t o M2.5 x 10-6 and with chloral hydrate M/165-5 to 2K/16,550 both together and separately. After forty- eight hours the roots of the plants were measured. Whilst in the single solutions growth was very slight when both substances were supplied simultaneously the growth was distinctly better especially when both substances are present in about equal amounts. The action of chloral hydrate in diminishing the toxicity of copper sulphate is similar although less marked to the influence of calcium over magnesium salts. Several explanations are suggested the most important of which is perhaps connected with the extent of ionisation which may be retarded when both substances are present. Or changes may be brought about in the plasma membrane which will modify the permeability of the limiting layer. Then again the effect may be the result of changes in the cell itself. N. H. J. M.

1. 1285 Organic Chemistry. Separation of Mixtures of a S a t u r a t e d with an Unsaturated Rydrocarbm by m e a n s of Permanganate. S. S. NAMETKIN ( J . Rusu. Phys. Chem. SOC. 1913 45 1423-ldS!l).-Attempts to determine the proportions of the constituents of mixtures OF (1) cyclo- hexane and cyclohexene and (2) m-hexane and hexylene by oxidising the unsaturated hydrocarbon by means of permanganate were un- successfiil owing t o the saturated constituent reacting to some extent with the oxidising agent. A similar method was then applied to analogous mixtures of gaseous hydrocarbons. For this purpose a special gas pipette was devised which permits the gaseous mixture to be passed repeatedly in small bubbles through the reqent and in which the latter does not 3ome into contact with mercury.After the reaction with saturated per- mznganate solution the excess of oxidising agent wds deJtroyed by Inems of saturated bisulphite solution both this and the perman- gnnate solution having been previously saturated with the saturated constituent of the gaseous mixture. With various mixtures of propane and ethylene propane and propylene and cyclopropane and propylene t l ~ e greatest error in the volume of the gas remaining aFter treatment with permanganate was 0.27%. The unsatisfactory results obtained by Kishner (this vd. i 153) are largely explained by the fact that in most cases the reaction was completed a t looo and hence under conditions which should lead t o attack of the saturated hydrocarbon.

Compare A. 1911 i 26 774 959; 1912 i 173).-The vast majority of organic com- pounds are essentially unstable and their great variety owes its exist- ence. to what the author terms passive resistance. It is quite conceivablo that polymerisation as a process directing molecule3 into more stable forms is very widespread and that most unsaturated organic com- pounds are able to polymerise under suitable conditions. No sharp line can be drawn bet ween association and polymerisation although with typical association no difference can be found between the chemical reactions of the monomeride and of the polymeride; it mag be that owing to ready dissociation of the latter only the former reacts or that no sufficiently sensitive reagent for the polymeride has been discovered.The stability of the complex molecule depends on the particular type OF polymerisation occurring in addition to the properties of the individual compound. I n the great majority of cases polymerisation occurs with formation of a ring system the ring having in all cases a n even number of atoms. In studying polymeric changes account must be taken of the isomerisa- VOL CIV. i. 4 ri. 1286 ABSTRACTS OF CHEMICAL PAPERS. tion so common with unsaturated compounds especially with rise of temperature. Among the hydrocarbons the principal well-defined types of poly- merisation a r e ( 1 ) the styrene type peculiar t o ethylenic hydro- cai*bons with unsymmetrical substitution of the hydrogen atoms by definite groups (phenyl) and yielding polymerides of high molecular weight and structures not yet definitely established ; (2) the stilbene type exhibited by ethylene derivatives with symmetrical replacement of the hydrogen atoms by certain groups (phenyl) ; (3) the acetylene type giving benzene derivatives ; (4) the allene type yielding cyclo- butane derivatives ; (5) the divinyl [A"Y-butadiene] type which forms cyclohexane derivatives and polymerides of uncertain constitution.If it can be shown that stilbene forms a polymeride and styrene a dimeride of closed-chain structure types (1) and (2) may have to be regarded as a single type; and further the resemblance between polymerides of the styrene and divinyl types (compare Oatromiselenski A 1912 i 280) may lead to the fusion of these two types. Most cases of polymerisation of unsaturated compounds containing hslogen nitrogen oxygen or sulphur may be referred to one of the above types.Polymerisation of the divinyl or A"Y-butadiene type is first con- sidered an account being given of all such hydrocarbons studied in this respect Experiments with isoprene and with diisopropenyl [fly-di- methyl-AEy-butadiene] show that (1) the relative proportions of dimeride and polymeride formed increase and diminish respectively as the temperature is raised; (2) at constant temperature the ratio between the proportions of dimeride and polymeride does not change during the heating ; (3) the reaction of polymerisation is sensitive to catalytic action Eince replacerrent of the air in the tube by nitrogen results (with Py dimethyl-A"Y-butadiene) in a fall of the relative amount of polymeride from 23% to 16.4%. It is further found that symmetrical hydrocarbons of this type such as A"Y-butadiene and its py-dimethyl derivative yield a single dimeride whereas the unsym- metrical isoprene gives two dimerides.I n contradiction t o the state- ment of Kondakov ('; Synthetic Caoutchouc its Homologues and Analogues," Yuriev 1912 p.. 101) and of Harries (A 1911 i 798) it is found t h it polymerisation of the pure hydrocarbons without catalyst yields no open-chain dimeride. I n general i t seems that no such equilibrium as that repres nted by dimeride Z monomeride polgmeride exists but that the processes of polymerisation are irreversib!e and proceed simultaneously in two direetions y.ielding dimeride and polymeride respectively.The existence of reversible processes of formation of dimeric and of poly- meric forms renders i t probable that such equilibria may pet be realised. The possible methods of formation and structures of dimerides and polymerides are discussed in detail.

The dimeride was investigated by Riiber ( A . 1004 i 569) who suggested formulac for i t and for the tribasic acid yielded on osidising it with permangan- ate. The author regards these fo~multe as inaccurate since according to his Echeme the dimeride should hare the structure a-Phenpl-hay-butadiene polymerises with great ease.and the tribasic acid CO,H*Cfi Ph*CH,*CH(CO,H)*CH,*CO,H the latter agreeing better with the analytical CH-$!H-CH*CH data than that proposed by Kiiber. As was shown by Stobbe and Reuss 1 yH2 1 //OH (A 1912 i S42) cyclopentadiene polg- UH-CH-CCJ-C H merises so rapidly t h a t intense cooling is necessary in order t o obtain i t in the monomeric form. If the type of polymerisation exhibited by open- chain hydrocarbons holds also for cyclic compounds the dimeride should have the annexed structure (compare Kraemer and Spilker A . 1896 i 289). This case is under investigation. Allene hydrocarbons polymerise with great ease and unlike those of the divinyl type with velocities varying only within narrow limits.The character of the polymerisation is also different the polymerides being cyclobutane derivatives and forming a n uninterrupted series from di- to hexa-merides. Actually however the polymerisation of allene hydrocarbons is complicated by transformation to the type shown by those of the divinyl series. This occiirs in two ways (1) the allene hydrocarbons undergo isomeric change into divinyl derivatives with \i. 1290 ABSTRACTS OF CHEMICA J PAPERS. comparative ease and (2) the dimerides are cyclic derivatives of divingl; thus that of allene has the structure and readily polymerises giving a di-dimeride and a polymeride. A t the ordinary temperature allene hydrocarbons polyrnerise so slowly that years e l a p ~ e before the formation of a n appreciable proportion of polymeride. But the temperature-coefficient of the velocity of the change is far greater than with divinyl derivatives and a t 150Othe velocity is approximately the same as with isoprene and diisopropenyl.The author elaborates a scheme to explain the mechanism of the pro- cess starting from the assumptions that the molecules combine initially at a single point and that the union is directed by two causes the magnitude of the affinity with the unsaturated atoms and the polarity. The construction of models of the polymeric forms shows that two types of arrangement in space are possible (1) the cyclic type in which the central carbon atoms of allene are arranged in a ring in one plane with the four-membered rings alternately on either side of this basal plane; and (2) the spiral type in which the central atoms of the allene groups are arranged in a spiral so that the first.fourth and seventh carbon atoms occupy analogous positions on the spiral and so on ; the four-membered rings lie in three mutually perpendicular planes the first fourth,! and seventh rings also taking up similar positions on the spiral. The dimerides of the two types are identical as also are the trimerides. Stereoisomerism is possible beginning with the tetrameride and assuming tho formation of polymeric forms according to both types two stereoisomerides may be expected for the tetra- penta- and hexa-meride. Higher degrees of polymerisation are possible only with the spiral type.

The author has devised a method for determicing the velocity at which polymerisation occurs. From 2 t o 10 grams of the hydro- carbon were sealed in tubes and heated in a perfectly dark thermostat a t 159+0.1'. After definite intervals of time the tubes were cooled and their contents introduced into tared distilling flacks connected with small condensers and tared receivers.Liquids with low boiling points were distilled at ordinary pressure and those with high boiling points under diminished pressure. A bath of Wood's metal was used for the heating its temperature being at first below the boiling point of the monomeride and finally about the boiling point of the dimeride. The monomeride the residual polymeride and some- times also the dimeride mere weighed to within 0.02 gram. I n general all the polymerised products were taken into account in calculating the velocity. The results obtained in this way mere corrected for several errors inherent in the method. The numbers obtained with twelve hydrocarhons of the AaY-butadiene series shorn t h a t (1) With isomerides the transference of a substituent from the extreme atom of a conjugated system of atoms to the middle atom is accompanied by increase in the velocity of polymerisation and conversely.(2) The formation of a ring frcm a cbaiii containing a conjugated system increases the velocity of polymerisation. (3) I n homologous series increase of the mass of a substituent a t the middle (or extreme) atoms of a conjugated system increases (or lowers) the velocity of poly- m erisation asuming that the heating occurs at corresponding temperatures. The results given by the four allene derivatives lead t o the following conclusions (1) The velocity of polymerisation of isomeric hydrocarbons of the allene series does not depend on the positions of the ~ubst~itiient groups.(2) I n an homologous series of allene hydrocarbons increase of the ma5s of the substituent results in increased velocity of polymerisation the heating being at corresponding temperatures.

The dimeride is separated by distillation ; when several are present! the predominating one is obtained by fractionation.

Further the dimerides of allene hydrocarbons exhibit marked optical exaltation which is usually about and greater than 2 ; dimerides from diethylene hydrocarbons of other types are optically normal.

On heating acetylene diluted with coal gas with hydrogen cyanide pyridiiie and its homologues were obtained. Mixtures of ammonia and benzene yield aniline when heated tho reaction being reversible. Further condensation of the aniline leads to carbazole and to benzo- nitrile the latter being formed by the action of hydrogen cyanide on aniline. I n all therefore seventeen constituents of coal tar have been identified as formed by the pyrogenetic condensation of acetylene. The hexylene formed is n-hexylene identical with that from mannitol.The formation of pyridine requires a temperature of 800' a t wbich the mixture of acetylene hydrogen and hydrogen cyanide can be heated without catching fire. Apparently the hydrogen cyanide acts as a poison towards the catalytic changes which bring abont the sudden decomposition of acetylene and cause a mixture of acetylene and hydrogen to catch fire much below 800'.

Xoc. 19 13 45 1420-1422).-Three methods exist for converting Eecondary nitro-compounds into ketones (1) Reduction of nascent isonitro-compounds by means of stannous chloride (compare Konovalov A. 1899 i 733) ; (2) Rction of acids on aqueous solutions of salts of isonitro-compounds (compare Nef A. 1895 i 3) ; (3) heating of halogen-substituted nitro-compounds (compare Widicenus and his collaborators A 1908 i 9'73; 1909 i 99; 1910 i 621 ; 1912 i 52).The last two methods are however only of theoretical interest. Nef's method yields besides the ketone (or aldehyde) more or less free nitro-compound which renders purification difficult whilst met,hod (3) is applicable only to those cases in which aggregation of several electro-negative groups t o one carbon atom renders the halogen-ORGANIC CHEMISTRY. i. 1297 substituted nitro-compound unstable. Konovalov's method gives excellent results. Investigation of the action of permznganate on nitro-compounds (compare A. 1910 i 830; Konovalov A. 1904 i 499; 1905 i 762) shows that; under the following conditions almost quantitative yields of the corresponding ketones are obtained. A solution of the nitro- compound in potassium hydroxide solution (1 part to 2 of water) is iiiixed with five to six times its volume of water and in the event of bepilration of insoluble nitro-compound the latter is extracted by means of light petroleum.To the aqueous solution mixed with pieces of ice in a large flask is gradually added the theoretical quantity of 1.5% potassium perrnanganate solution the ketone being subsequently distilled in a current of s t a m . I n this way nitrocyc2ohexane gave a 97% yield of cyclohexanone and nitrofluorene a 96% yield of fluorenone. T. H. P. Structure of isoNitro-compounds. S. S. NAMETICIN (J. Russ. I'hys. Chem. SOC. 1913 45 1414-1420).-'L'ne author criticises the arguments advanced by Steinkopf and Jiirgens ( A 1912 i 152) i n support of Hantzsch's formula for isonit ro-compounds. Stress is laid on the unsaturated character of these compounds which react with halogens and halogen hydracids and in alkaline solution even in the cold instantly reduce 1-2% potassium perman- ganate solution the nitro-compounds being converted almost quanti- tatively into ketones (compare preceding abatrac t).Such ready oxidisability is difficult to explain according t o Hantzsch's ring constitution but is easily understood if the presence of a double linking is assumed as is the case in the structure proposed by Michael and Nef. If oxidation a t a double linking between carbon and nitrogen follows the same course as at one between two carbon atoms the initial product oE the reaction should be a compourid exhibiting a n accumulation of hydroxyl groups and hence possessing but slight stability; loss of the elements of water from this compound would yield ketone and a nitrite =C:NO*OK -+ =C(OH)*NO(OH)(OK) The behaviour of salts of primary nitro-paraffins on acidification which yields transitory nitroso-compounds and finally hydroxitmie acids is also readily accounted for on the basis of Michael and "el's formula UHR:NO*OH -+ CHR:O+ :NOH + CHR(OH)*NO -+ Clt(0H):NOH.When however the nitro group is accompanied by a more or lesa electronegative group this intermediate formation of nitroso-compound does not take place as n o blue or green coloration then makes its appearance. Such an essential variation in one and the same reaction leads the author to suggest that the first stage in the action of dry hydrogen chloride is most probably a direct com- bination the unstable compound thus formed subsequently undergoing intramolecular rearrangement and loss of water CI..R:NO*OH + I n thoae cases where the isonitro-compound and the product of its union with the hydrogen haloid exhibit particularly slight stability -+ =GO + KNO + H20.HCI -+ CHRCI*NH(OH):O -3 CHRCl*N(OH) -+ CRC1:NOH.i. 1298 ABSTRACTS OF CHEMICAL PAPERS. the loss of water may partly precede the rearrangement; a nitroso- compound would thei) be formed a? intermediate product CHR NO*OH -+ CHRCl*NH( OH) 10 -+ CHRCl *NO -+ CKCl NOH. Analogous interpretations suggest themselves for the formation of halogen-substituted nitro-products nitrolic acids and ~,h-nitrolee.

H. P. Nitrosites of the Aliphatic Series. K. V. SIDORENKO (J. Ziuss. Phys. Chem. Xoc. 1913 45 1585-1604).-The author has devised an improved method for pi eparing ethylene nitrosite (compare Demjanov A. 1899 i 845) a number of reactions of this compound being studied. When heated in asealed tube with dilute hydrochloric acid (1 l ) i t yields hydroxgldmine apparently according to the equation (C2H403N2)2 + 4H20 + 4HC1= SCHO*CO,H + 4NH,*OH,HCI. At the ordinary temperature i t is dissolved by concentrated sulphuric acid from which i t is precipitated unchanged on dilution. Nitric acid seems to be without action on i t in the cold but in the hot yields oxalic acid.With aniiine in absolute alcoholic solution i t gives a basic com- pound and this with hydrochloric acid yields a crystalline substance which is dificult t o purify and gives poor results on analysis. Under similar conditions p-nitroaniline acts on it apparently as a catalyst being obtainable unchanged from the products of the reaction. With benzylamine i t reacts in accordance with the equation (C2H403N,) + NH,*CH,Ph = (C,H,0,N2)2:N*CH,Yh + N20 + H,O the unstable compound thus obtairied crystallising in long colour- lees silky prisms and exhibiting normal cryoscopic behaviour i n benzene. With dibenzylamine i t reacts thus (C2H40,N2) + 2NH(CH2Ph) = 2C,H402N*N(CH,Yh) + N,O + H20 the compound formed crystallising in long prisms m.p. 74*6-75-2" and possessing the normal molecular weight in freezing benzene. This compmnd exhibits feeble basic properties ; it exerts a scarcely perceptible alkaline reaction on litmus and yields no salts oven with strong acids. When reduced with tin and hydrochloric acid i t yields a sparingly soluble hydrochloride which forms a platinichloride insoluble in alcohol. Accompanying the dibenzylamine derivative is a small quantity of a compound which separates in crystalline granules and possibly represents the result of combination between the amine and the nitrosite after the latter is resolved into two separate molecules. From these results the conclusion is drawn that ethylene nitrosite has the structure N202(CH,*CH,*N0,)2 and thus belongs t o the class of #-nitrosites (compare Wieland A.1904 i 54). T. H. P.

The value for the vapour pressure given by Marshail ( J . Xoc. ChenL.

F. M. G. M. Ferri- and Chromi-formates. BUDOLF I?. WEINLAND :tnd HANS REIHLEN (Bey. 1913 46 3144-3150).-The compounds formed wheri a ferric salt is treated with sodium formate have been studied. I n the deep red solution which resiilts when equivalent quantit.iea are mixed there is present the cation [Fe3( H*CO,),] of the hexaformato-triferri- base of which only the monoformate has yet been isolated (Belloiii A. 1909 i 283; Tower 1910 ii 900). By the addition of solid sodium formate to such a solution the red colour gradually becomes pale and trisodiunz hexaforrnatoferrate [Fe( H *C0,),]Na3 separates in pale green microscopic rectangular tablets.Thus in presence of much sodium formate the anion [Fe(lI*CO,),] of hexaformatoferric acid is formed. This recalls the deep green of the trioxalatoferri-anion. By the action of water the pale green solution or salt becomes red the complex ions being in equilibrium. The composition of the red formates which are formed when ferric salts are mixed with sodium formate varies and the formic acid conteDt rises with the concentration of that acid in the solution. It is therefore probable that in these substances there may be present salts of the hexaformatoferri-base with the hexaformatoferric acid Brick-red microcrybtalline conzpou~zds which agree with the formulat [ Fe( H*C02)G] [Fe,(H*CO,),] 8H,O and (H*CO ) [Fe(H* cO,)G] pe3 (OH),' '1 3\14 K,o have been prepared.From a solution containing 30 mols. of sodium formate to one of chromium nit rate tvisodium hexcformatochrornate [ Cr( H-GO,),] Na,. 4.5 H,O cry s- stallises in greenish-violet rhombohedra which are only decomposed by ammonia after prolonged boiling. Two Isomeric Forms of Anhydrous Sodium A c e t a t e . DANIEL VORLANDER and OTTO NOLTE (Ber. 1913 46 3199-3212).-An anhydrous form of sodium acetate is obtained on fusing sodium acetate trihydrate below looo and it also crystallises from fused godiurn acetate Intermediate hydrates do not exist. This modification is isonieric with that obtained on cooling the amorphous flux prepared by dehydrating above 200'. The new low temperature modification crystallises i n the rhombic system and pbsses into the isomeride a t 198O.The change is enantiotropic the reverse change taking place so slowly that the two forms can exist side by side for months. The decomposition temperature of the trihydrate into water and anhydride is 88.2'. Both anhydrous forms when crystallised from absolute ethyl or methyl alcohol yield the new rhombic form. This is an excellent condensation agent absorbing water much more quickly than the ordinary fused form. For such gurpows the trihydrate is best dehydrated a t 120-160'. Similar phenomena occur i n the case of chromium salts. J. C.

The Solidifying- and Melting-points of Mixtures of S t e a r i c and Oleic Acids. ROBERT MELDHUM (Che??a. News 1913 108 199-20 l).-The investigation was undertaken t o confirm the degree of accuracy of Dalican’s method of determining the solidifying point and the thermometer bulb method of determining the melting point of mixtures of fatty acids.I n the first series of experiments the Solidifying points mere taken in a test-tube 7 inches by 1 inch filled three parts full which was suspended in a glass jar. The mixtures of acids were melted and cooled to within loo of their solidifying point. The thermometer was inserted and when crystallisation had commenced the whole was very slowly stirred until the thermometer ceased to fall when the latter was fixed in the centre 14 inchesfrom the bottom and the readings com- pleted. The point at which the thermometer rose and remained stationary was taken a s the solidifying point. The method yields very concordant results for any given mixture and contrary t o the general belief indicates the composition of the mixture more accurately when the solidifying point is low than when i t is high.A second series of experiments was performed in the same apparatus but without stirring. The results are concordant among themselves but both rise and solidifjing point are lower than indicated by the first method. The rise appears to be rather erratic and is apparently governed by the amount of matter crystallised per given interval of time. When working with large quantities i t appears to be eliminated. A sbries of determinations of m. p. has also been made ( I ) by cover- ing the thermometer bulb with a thin layer of substaiice and suspend- ing it inside a test-tube which is gradually heated in a beaker of water; (2) by the closed capillary tube method; (3) with a n open capillary and (4) with a capillary U-tube both limbs of which are left open.One limb contains a column of solid f a t 4 cm. long The tube is heated in a water-bath the thermometer being placed between the limbs. The temperature at which both columns of fat are at equal height is taken as the m. p. The conclusion is drawn that the bulb method is the most accurate the chief difficulty in it lying in obtaining a uniform coating of the fat. I n the methods which depend on the displacement of the column of solid (Nos. 3 a s d 4) movemeut occur8 before the latter is completely molten. E. F. A. H. W. VOL.

DiethyEmalonic Synthesis of Formaldehyde from Carbon Dioxide and Water by Inorganic Colloids acting as Transformers of Light Energy.BENJAMIN MOORE and T. ARTHUR WEBSTER (Proc. Roy. Xoc. 1913 [B] 87 163-176).-The experiments of Bach Euler Usher and Priestley (compare A 1906 ii 299 881) have been confirmed and extended to show that formaldehyde is synthesised from carbon dioxide by means of inorganic colloidal uranic and ferric hydr- oxides in very dilute solution. The colloids act as catalysts for light energy positive results being obtained only in strong direct sunlight and in a '' uviol " mercury arc. Under similar conditions crystalloid uranium nitrate does not cause synthesis. The uranium catalyst is more powerful than the ferric catalyst. It is claimed that such a process occurring in nature forms the lirst step in the origin of life. ccnhyd?-ide prepared in a similar manner is a liquid.c. 8. E. F. A.

Aldol may be readily prepared in good yield (30 grams) by a method devised by Zelinski arid Volkonski but not j e t published.I t consists i n mixing acetaldehyde (100 grams) dissolved in an equal weight of water with freshly precipitated alkali-free lead hydroxide (30 grams) at a temperature not exceeding 5" the mixture being left at the ordinary temperature for two hours and then gradually heated on the water-bath at 25") 30° and 35' during eighteen hours. I n presence of lead hydroxide aldol and formaldehyde give pentaerythritol so that resolution of the aldol molecule into 2 mols. of acetaldehyde precedes condensation with formaldehyde The action of lead hydroxide on aldol is hence a typical reversible reaction (compare de Bruyn and Alberda van Ekenstein A. 1899 i 850; Lob A 1909 i 767; Lob and Pulvermacher A 1910 i 95). Pentaerythritol is also obtained from aldol and formaldehyde in presence of calcium hydroxide but the latter is not able to effect the condensation of acetaldehyde to aldol. T.H. P. Mechanism of Oxidative Changes. HEINRICH W IELAND (Be?.. 19 1 3 4 6 3327-3342).-'L'he catnlytic action of palladium or platinum is not due t@o the activation of molecuiar oxygen with intermediate formation of peroxide but it is attributed to the activation of hydrogen. This theory is extended to biological oxidations and it is shown that certain of these can take place in presence of palladium black and in the complete absence of oxygen provided that the accumulated hydrogen is removed by the presence of other substances with an afIinity for hydrogen such as p-benzoquinone or methylene-blue. Dextrose can be dehydrogenated by shaking with palladium black at 40' in a n atmosphere of nitrogen carbon dioxide being formed from the beginning of the reaction as well as hydrogen.The change is accelerated on the addition of 12-benzoquinone which is converted into quinhydrone or of methylene-blue which is decolorised. I n presence of oxygen which forms water with the liberated hydrogen the change is still more rapid. Gluconic acid is even more quickly dehydrogenated. Phenol m-cresol guaiacol pyrogallol and aniline can be dehydrogenated in the absence of oxygen. Tyrosine and uric acid are resistant but in both these cases the action of the oxydase is known to be combined with that of a hydrolgsing enzyme. Alcohol in presence of methylene-blue or of p-benzoquinone is con- verted into acetic acid by a n acetone preparation of acetic acid bacteria all oxygen being excluded Acetaldehyde behaves similarly whereds methyl alcohol or formaldehyde are converted into formic acid.Dextrose is dehydrogenated by the acetic acid ferment in presence of methylene-blue carbon dioxide being formed. The reducing enzymes for example Schardinger's reducttzse act in the same manner. Salicylaldehyde is converted into salicylic acid by the milk enzyme either in presence of oxygen or in presence of methylene- blue in the absence of oxygen. Lactic acid yields pyruvic acid under similar conditions. E. F. A.ORGANIC CHEMISTRY i. 1305 Biochemical _Synthesis of a Sugar of the Hexobiose Group Gentiobiose.

Synthesis of Amido-oxalylbiuret. JOHAN TH. BORNWATER (Proc. K . rlkad. JVetensch.

Subsequently the subject has been re-investigated by Biltz and Topp (this vol.i 600 602) who are led to the conclusion that the two substances are probably identical although certain differences remain unexplained. The author points out t h a t Grimaux's compound has been incorrectly dew ribed as oxalyldiureide in the German literature since Grimaux calls it '' amide d'un acide oxalyibiur6tique." H e has further effected the synthesis of the latter compound. D. F.

When the reagents are added in the reverse order and more concentrated solutions of potassium hydroxide are employed (compare Biltz and Topp Eoc. cit.) there is a possibility that the substance is already undergoing partial decomposition before the copper sulphate is added.

Compare Wallach this Journ. 1875 351 ; A. 1878,285 288 ; Pinner this Journ. 1877 ii 584 ; A. 1884 1298). -With the object of throwing further light on the mechanism of the transformation of chloral into dichloroacetic acid under the influence of aqueous potassium cyanide the authors have undertaken systematic examination of similar cases of simultaneous reduction and oxidation occurring in compounds of the type CCI,*CH(OH)*R the present paper dealing particularly with the transformation of PPP- trichlorolactic acid and its nitrile and ester into the corresponding derivatives of dichloropyruvic acid.They consider that the first stage in the reaction between chloral and potassium cyanide consists in the formation of PPP-trichloro- lactonitrile (I) and that this loses hydrogen chloride yielding the com- pounds (11) or (111) which are at once transformed into dichloro- pyruvonitrile (IV) the latter compound then undergoing hydrolysis to dichloroacetic and hydrocyanic acids (I) CCI,*CH(OH)*CN -+ (11) CCI,:C(OH)*CN or 0 /\ (111) CCl,*CH*CN --+ (IV) CHCl,*CO.CN -+ CHCl,*CO*OH + H CN. The following evidence is given in support of the view that PPP- trichlorolactonitrile is intermediately formed in the reaction (1) A l t bough potassium cyanide is hydrolysed to potassium hydroxide and hydrogen cyanide the action of potasEium cyanide on chloral does not give rise t o chloroform and therefore the chloral cannot be present as such in the mixture.(2) PPP-Trichlorolactonitrile on treatment with potassium hydroxide gives riw to potassium dichloroacetate no chloroform being produced in the reaction.i. 1310 ABSTRACTS OF CHEMICAL PAPERS. /3/3/3-Trichlorolactonitrilt thus differs from chloral in not under- going hydrolysis with the formation of chloroform. This difference is referred by the authors to the reactivating influence of the cyanogen group on the hydrogen atom directly attached to the central carbon of the nitrile; on account of this mobility of the hydrogen atom the molecule readily loses hydrogen chloride whilst at the same time the ability t o yield chloroform by hydrolysis disappears. A similar differance is shown by /3/3P-trichloroethyl alcohol ethyl ppp-trichlorolactate and other compounds of the type CCI;CH(OH)*R.On treatment with triethylamine ethyl P/3/3-trichlorolactate and /3~/3-trichlorolactonitrile lose hydrogen chloride yielding ethyl dichloro- pyruvate and dichloropyruvonitrile. The last-mentioned compound reacts with water and alcohol yielding dichloroacetic acid and ethyl dichloroacet ate. The formation of dich loroace tamide dic hloroace t anilid e and e t hy 1 dichloroacetate by the action of ammonia aniline and alcohol on pp/3-trichlorolactonitrile (Pinner and Wallach Zoc. c k ) is considered by the authors to furnish additional support to their view that dichloropyruvonitrile is formed as an intermediate product in the action of potassium cyanide on chloral.When heated with water or triethylamine trichlorolactic acid decomposes thus CC1,-CH(OH)*CO,H -+ HCI + CHCI,*CO*CO,H The readiness with which this decomposition takes place affords a n explanation of the fact that the interaction of trichlorolactic acid and ammonia hydroxylamine phenylhydrazine or carbamide gives rise to derivatives of glyoxal or dichloroacetaldehyde.

HERMANN PAULY and ERNST WALTZINGER (Ber. 1913 46 3129-3140).-It has already been shown (A. 1910 i 639) that tetraiodoglyoxaline decomposes on beating to form the compounds C,N,I and then C,N the reaction recalling the formation of paracyanogen from cyanuric iodide (Klason 1886 1091). The fact that the decomposition takes place at a temperature which according to experience is not inimicable to the glyoxaline ring suggests that the compounds formed still have ring structure since a partial loss of nitrogen might be expedted to ensue if the ring were opened.I n order to test this point and also to learn whether the preliminary decom- position into a monoiodo-compound was general tri-iodo-5- and 2-methyl- glyoxalines and tetraiodopyrrole (iodole) have also been heated. I n these casep however the compounds melt and enclose some of 'the liberated iodine so that the formation of intermediate compounds was masked and in addition the presence of hydrogen was disturbing and led to the production of a little ammonium iodide All the compounds obtained C,N C,N,Me and C,NH are amorphous charcoal-like products and have in common with para- cyanogen the following properties they yield cyanogen on heating to redness in an indifferent atmosphere; they give up all their nitrogen as ammonia when heated with soda-lime; they dissolve in molten alkalis forming ammonia cyanides and carbcnates.Animal charcoal has someof these properties but does not dissolve in molten alkali. It may consist in part of such nitrogen carbides. Quantitative studies on the decomposition of tetraiodoglyoxaline were carried out in a glass tube which was slightly bent downwards so that it dipped below the surface OF a metal bath. One end of the tube was attached to a U-tube and a flask containing potassium iodide solution for the absorption of iodine. The iodine was swept out by a stream of carbon dioxide. Since the tetraiodoglyoxaline cannot be purified by recrystallisation it was analysed before use. I t was found that however carefully prepared i t contained about 1% of a by-product which could be removed by volatilisation at l 0 5 O in vacuum. The carbides obtained readily absorbed gases and moisture so t h a t all analytical processes were carried out with the greatest expedition.The formation of the soot-like sepia-coloured ioclo-nitvojen carbide (C,N,L) takes place at 180'. The substance forms a brown solution in nitric acid iodine being liberated. The carbide (C,N,) is best obtained by heating tetraiodoglyoxaline first at 180' and then a t 420'. When heated at 800-900' in a current of carbon dioxide cyanogen and a little carbon monoxide were formed but in an atmosphere ol nitrogen the formation of cyaoogen was quantitative. J. C. W.

Action of Organomagnesium Compounds on Ethyl Diazo- acetate. ERNST ZERNEI~ (Monatsh. 191 3 34 1609-1 63O).-Sy means of the reaction between organomagnesiurn compounds and ethyl diazoacetate or diazomethane the author hoped to be able to throw some light on the constitution of aliphatic diazo-compounds. No direct proof of the ring or open-chain structwe could be obtained but the results offer more support to the latter view than t o the former. The author critises the Angeli-Thiele formula R:NiN however and proposes instead the type R:N*N making the active nitrogen atom univalent.Although Thiele has suggested that certain reactions of nitrous oxide agree with the constitution O:NiN i t was found that the gas has no action whatever on magnesium methyl iodide.

To elucidate this point the action of ethyl diazoacetate on magnesium phenyl bromide mas investigated since i t was expected that either the known phenylhydrazone of ethyl glyoxyldte or a n isomeride would be obtained. However the only crystalline product was one in which the ester group had also been attacked.I t was most probably the phenythydrazovce of I~~ldrozydiphl:IzyEncetaldehyde OH*CPh,*CH:N*NHPh.

The red compound gave intense red solutions in concentrated mineral acids. On evaporating the soliltion in hydro- chloric acid in a desiccator over lime a snow-white additive product C,,H17N,CI was obtained This was very eparingly soluble iu water but gave a turbidity with silver nitrate. It was freely soluble in organic media and exhibited a fine blue fluorescence inalcohol.Here again the crystalline product might have been the hydrazi-compound OE€*CPh,*CH< I but this did not give a condensation product with any chromophoric groups. Magnesium ethyl iodide and ethyl diazoacetate mere also brought tcigether and ethylhydrnzine sulphate was obtained by hydrolysing the unpleasant smelling bi own syrup which resulted.

Chew&. ~oc. 1913 . 35 1’732-1 741).-When solutions of mercury alkyl salts in liquid ammonia are electrolysed the free mercury alkyl group is deposited at the cathode except in the case of members of the series above C,H,Hg when no deposition takes place. The elect8rolytic cell used contained smd1 platinum wires as electrodes the cathode being situated at the bottom of the cell. The free groups deposited as a n attenuated opaque mass which by means of pressure could be brought into a fairly coherent form.They are good conductors of electricity and do not amalgamate with mercury to any extent. The mercury methyE group HgCH was obtained pure from the compound MeHgC1 by washing it free from salt with liquid ammonia. Decomposition takes place at ordinary temperatures with the forma- tion of mercury and mercury methyl HgMe,; there is appreciable decomposition at - 33’. The ethyl derivative behaves similarly but the propyl derivative is less stable. The ethyl mercury group when compressed exhibits metallic reflection of a copper colour whereas the mercury methyl group is black. Attempts t o isolate groups by the electrolysis of liquid ammonia solutions of the following salts were not successful Me,SbI Me,SI Pb,T I C,H,,HgI C,H,,HgI PhHgI and Me3SnI. The bearing of the above results on the metallic state is discussed and the conclusion drawn tjhat the electrons to which conduction is due in metals are the same electrons which are involved in the common chemical combination of metals with other elements.T. S. P. The O p t i c a l Activity of Petroleum and its Significance. FRANK W. BUSHONG (Science 1913 38 39-44).-Attention is drawn 50 the optical activity of the heavy oils. Sinco the napbthenic acids derived from the petroleum by treatment with alkali during refining are optically active the activity of the original oil might be attributed t o these acids. It does not necessarily follow however that the optically active constituents present in these naphthenic acids are identical with those originally present in the petroleum and there seems good evidence that this is not the case as both the author and others have found that the heavy oils retain most of their optical activity after treatment with alcoholic potash ; still the optical activity may be due tosome extent to these acids.It is probable that the oils contain active hydrocarbons (naphthenea) and i t is generally held that t h e naphthenic acids are oxidation products of these. [The author’s views as to the cause of the activity of petroleum were somewhat misrepresented in an earlier abstract (this vol. i 969).] J. C. W.ORGANIC CHEMISTBY i. 1315 Distillation of Coal under Reduced Pressure. AA& PICTET and MAURICE BOUVIER (Ber. 1913 46 3342-3‘353; Compt.rend. 1913 157 779-781).-1n a n earlier paper (Pictet and Ramseyer A. 1911 i 850) i t has been shown that extraction of coal (Montrambert) with boiling benzene gives a mixture of hydroaromatic hydrocarbons from which a hexahydrofluorene CISHIG could be isolated; i t was also mentioned that distillation OF the same coal under reduced pressure produced a similar mixture in which the same hydrocarbon could be detected. As the latter procedure was more rapid and gave better yields it has now been applied more carefully. The method was t o heat 2-5 kilograms of the coal in a vertical iron retort of approximately 10 litres capacity ; the temperature was slowly raised to 450° whilst the pressure was maintained at a few centimetres of mercury by means of water-pumps. The experiment generally occupied about five hours.Of the products of the decomposition the tar only was carefully in- vestigated ; the gases were not collected but were observed to resemble butadiene and isoprene in odour ; the water had a n acid reaction and contained no ammonium salts ; the coke was found to yield still further quantities of combustible gas when heated more strongly. The tar which amounted t o approximately 4% of the coal was lighter than water had a brown colour with feeble green fluorescence and re- sembled petroleum in odour ; i t contained no phenols but a considerable quantity of bases which appeared t o be mainly of the secondary type. Careful fractionation under reduced pressure failed to disclose the presence of any solid substances and oxidation yielded only aliphatic acids indicating the absence of aromatic hydrocarbons.It is there- fore probable that the t a r is a mixture of hydroaromatic compounds of the naphthene class. Decomposition of the crude tar by distillation a t ordinary pressure through a red-hot iron tube packed with coke produced a considerable quantity of gas resembling coal gas in odour and consisting mainly of hydrogen and paraffin hydrocarbons together with water containing much free ammonia and a dark-coloured t a r resembling coal-tar in odour. This tar unlike the original product contained phenols bases recalling the odour of pyridine and aromatic hydrocarbons amongst which benzene naphthalene and anthracene could be identified. It is tentatively suggested that in coal distillation the methane ammonia phenols and aromatic hydrocarbons are not primary products but are formed by the decomposition of intermediate products represented by the above “ vacuum tar.” Treatment of certain fractions of the “ vacuum tar ” with sodium removes certain hydroxy-compounds (the presence of which had already been indicated by tire results of analysis) which exhibit the usual behaviour of alcohols towards alkalis and acyl chlorides.The natural supposition that these alcohols form the origin of the phenolic substances during subsequerit decomposition by further heat received no confirmation when they were passed in the vapourous condition through a r e d - h o t tube the only products being unsaturated hydrocarbons. The hydrocarbon residues after extracting various fractions withi.1316 ABSTRACTS OF CHEMICAL PAPERS. sodium immediately decolorise cold potassium permsnganate solution and consequently must contain unsaturated hydrocarbons. The latter were removed by the action of fuming sulphuric acid and the residue again heated with sodium. By repeated fractional distillation the liquid was separated into various portions in the hope of identifying some of the constituents. Decahydronaphthalene was definitely proved to be absent and a comparison of the compositions and densities of the various fractions with th0L.e of corresponding fractions from Caucasian p6 troleum c1 early de rn on s trated their distinct character. A similar comparison with fractions from Canadian petroleum (which is also knowu to contain hydrocarbons of the general formula CnH2n) proved the identity of the fractions containing the hydrocarbons C,,H, and C1,H2,.The former of these is very sensitive to most reagents arid generally gives complex reaction products but by the action of bromine vapour dibromodureue (?) m. p. 20P could be obtained; also by distillation over iron oxide at a dull red heat a distillate is obtained which on nitration yield6 dinitrodurene (?) m. p. 202’. Although this evidence is not regarded as final the authors consider themselves justified in identifying the hydrocarbon C10H20 with hexahydrodurene (s-tetramethylcyclohexane) whilst to the hydrocarbon CllH22 they ascribe the structme of a pentamethgl- c yclohexane.

Although purely mathematical considerations fail to decide with which oxygen compound (for example acid or alcohol in esterifica- tion) the complex oxonium ion is produced some decision can be drawn by analogy to the conversion of imino-esters by ammonia or ainines into awidincs which is also accelerated by acid.I n this case the change may occur by interaction of the ammoriium ioii with the free irnino-ester or of the iniino-ester cation with free ammonia according to the alternative schemes CPh(:NH)*OIMe + H*NH,+ -+ CPh*C(NH2)(0111e).NH,+ -+ CPh(:NH)*NH," + MeOH or CPh(OMe):JSH,+ + HNH -+ CPh(NH,)(OMejNH,+ -3 CPh*C(:NH)NH,+ + MeOII. According to the latter scheme the salts of tertiary amines should be unable to form amidines from imino-esters and according to Pinner this is actually the case.The conclusion is therefore t o be drawn that in the formation of amidines from inzino-esters and amines in the presence of acids action occurs between the arnine (or arnmouia) and the ion resulting from the additive compound of the imino-ester with the acid. Extending this analogy to the hydrolysis o r formation of esters it is in these cases most probable that the action is of a hydroxide water or alcohol on the oxonium ion of the ester or of the organic acid.

The diphenolate forms various hydrates which may be expressed by the general formula 2Ca(OH),,4PhOHY(2n + 1 )H20 where n = 0 1 2 3 or 4. The diphenolate is capable of combining with phenol giving tho tetrt~phenolate Ca(0 H),,4PhOH and the hexaphenolate Ca(OH)2,6PhOH. Calcium hydroxide and phenol are also able to form hygroscopic solid solutions which separate in needles apparently of the rhombic system and do not dissolve in water but give with i t a n oily and a n aqueous layer (compare Runge Ann. Phys. Chem. 1834 31 69 ; 32 308) exhibiting a n alkaline reaction.Similar solid solutions are formed by calcium hydroxide and thymol and by magnesium hydroxide and phenol. T. H. P.

Of the two possible form;dze \ OH and NPh:N/--\OH the former is rendered more probable by the work of Bechhold (A. 1889 1155) on the corresponding methyl other but the evidence is far from satisfactory. The reduction products obtained from the nitrosoresorcinol ethers of the structure NO/ \OH where R repre- sents the methyl or ethyl radicle (Henrich and Rbodius A. 1902 i 447) will by comparison with the reduction products of the above azo-compounds fix definitely the constitution of the latter. Experi- ment shows that it is the o-amino-ether which is identical with the corresponding ether above so that the first of the two possible formula3 for the etbyl (and methyl) ether is the correct one alkylation having occurred in the para-position.Improved methods are described for the methylation (by methyl sulphate) and ethylation of the benzeneazoresorcinol. \ -/ O H OR ‘OR and NO ’ \-/ \-/ D.

The liquid nature of many of ths basic derivatives of diphenyl- methane and the frequently indistinct melting point of their salts has led the authors to investigate the suitability of their nitro-deriva tives in characterising them.They seem to be generally well adapted for this purpose.

I n this connexion the following substances have been prepared 2 2'-dinitro4 4'-tetrasnethyZdiaminodi-m-tolyl- methane CH2[C,H,Me(N0,)*IY1SiIe2-J2 yellow leaflet. m. p. 125' ; 4 4'-dinitro-2 2'-tetramethyldiaminodi-n~-~olylmethane m. p. 102" which on reduction yields the corresponding rli-amino-compound ; 2' ; 4-dinitro-2 ; 4'-tetrccmethyldiainin~;ul~e7zyl-m-tolylmct?~ane NMe,*C6H2Me(N0,) CH,*C,H ,(NO,)*NJIe dark red crystals m.p. 187' which is reduced to t h s dianzino- derivative colourless crystals m. p. 1 4CJ0 ; 2'-nityo-2 4'-tetramethpZ- cJiaminopiieizyl-m-totyZ~etf~ane N~~e,*C,H,~~e*CH2.C,H,(N0,)*2Ji\Ie2 red crystals m. p. 94' ; corresponding ar~~z~zo-co~wpouud m. p. 97-98". According to Biehringer (A. 1897 i 73) 2 2'-diamino-4 4'4etra- methyldiaxninodiphenylmethane loses ammonia when heated with hydrochloric acid with formation of an acridiue ring. The authors find that a similar ring formation does not accur when the hydrogen atoms of the amino-group are replaced by methyl. When heated with hydrochloric acid at a temperature not exceeding 180° the bases are unchanged ; under more drastic treatment formaldehyde is eliminated but the liberation of methyl- dimethyl- or trimethyl-rtmine could not be detected.H. W. Tertiary Derivatives of 0- and p-Aminobeneyl Alcohol. 111. JULIUS VOK BRAUN and OTTO KRUBER (Ber. 1913,46,3460-3470).-1n previous papers (A 1912 i 968; preceding abstract) the authors have shown that tertiary aromatic amines of the dialkylaniline type readily condense with formaldehyde either alone or in the presence of hydrochloric acid yielding derivatives of 2 2'- and 4 4'-tetra-alkyl- diaminodiphenylmethane CH,(C,H,*NMe,) and of u- and p dialkyl- aminobenzyl alcohols. The reaction has now been extended to the following amines in order to ascertain the effect of nuclear substituents on the course of the condensation (1) dimethyl-m-toluidine (2) diethyl-m-toluidine (3) dimethyl-m-chloroaniline (4) phenylbenzyl- methylamine ( 5 ) dimethylcumidine (6) dimethyl-p-chloroaniline,ORGANIC CHEMISTRY.i. 1321 ( 7 ) dimethyl-p-bromoaniline (8) dimethyl-p-bron~o-nz-tol~ii(l~ne 2nd (9) dimethyl-o-chloroaniline. The meta-substituted amines ( 1 ) and (S) resemble the unsubstitutecl dimethylaniline in that they are almost quantitatively converted by the theoretical amount of formaldehyde (8 mol.) into the corresponding diphenylmethane derivatives whilst with excess of formaldehyde only small yields of the dialkylaminobenzyl alcohols are obtained. The behaviour of the para-substituted amines (5)-(8) is similar to that of dimethyl-p-toluidine. They do not form diphenylmetbane derivatives but with excess of the aldehyde give rise to the dialkylaminobenzyl alcohols in good yield. I n the case of the amines 6 7 and 8 containing R halogen atom in the para-position to the dimethyiamino-group the prolonged action of formaldehyde in the presence of hydrochloric acid causes partial oxidation of the alcohol to the corresponding acid.It is also found that dimethyl-o-chloroaniline condenses with formaldehyde much more readily than dimethyl-o-toluidine and the conclusion is therefore drawn that the inhibiting effect of ortho- substituents on the reactivity of the para-hydrogen atoms of the dialkylanilines is not always the same (compare Friedlander A 1899 i 350) but may vary considerably with the nature of the substituent.

The addition of methyl iodide t o tertiary aromatic amines is however not particularly subject to steric influences and the authors have therefore examined the behaviour of the above amines towards cyanogen bromide and iodoacetonitrile. With respect to the action of cyanogen bromide on tertiary aromatic amines it has already been shown that whilst sterically unhindered amines react with extreme ease at the ordinary temperature yielding compounds of the type R-NMe,Br and R-NMe’CN amines containing an ortho-substituent enter into reaction with great difhulty.I n the case of iodoacetonitrile tho presence of a n ortho-substituent completely suppresses the reaction. In agreement with the results obtained by the addition of methyl iodide it- was found that tho di-o-substituted aniines 2 4 and 9 do not react with either cyanogen bromide or iodoacetonitrile whilst the amines 5 7 8 and 10 containing a substituent in the ortho-position to only one of the dimethylamino-groups enter into reaction as*readily as the amines 1 3 6 in which steric influences are completely absent t h e reactions prcceeding according t o the following scheme CN’Br CH2(CGH4*N&Ie,) -+ CH2(CGH4*N&Ie3Br) and CH,( C,H,*NMe,) CH,(C,H,*NJIe-CN),. -+ N Me&* C,H,*C R,*C,H;NMe-C H2* CN + CH,(C,H,*NMe*CH,*CN)2 and CH,(C,H,-NMe,I) CH2I’CU That the presence of meta-substituents has little effect on the inter- VOL.CIV. i. 4 2 Li.

Compare A 1912 i 971).- The greater part of this paper has been already abstracte.3 (this vol.i 11 83). The author further shows experimentally that in the action of 3 mols. of diphenylmethjl ethyl ether on magnesium propyl iodide under the conditions employed by Tschelincev and Pavlov (this vol. i 461) part of the etherate passes into solution. Duiing distillation this etherate is subjected to a very high temperature (280°),and it is hence not surprising that i t decompoees with formation of tetraphenylethane. Other results obtained by these authors are also criticised. Gorski's results (this vol.. i 462) axe not new (see Oddo k. 1911 i 443). T. H P. Triphenylthiocarbinol. DANIEL VORL~NDER and ERNST MITTAG (Be?.. 19 13 46 3450-3460).-Although triphenylcarbinol contains three phenyl groups its acid properties are no greater than those of an aliphatic alcohol.It has however more pronounced basic properties than any other tertiary alcohol and shows a marked tendency to lose its hydroxyl group This behaviour is in accordance with the rules laid down by Vorliinder (A. 1902 i 309) according to which the reactivating influence of unsaturated groups on adjacent atoms or groups attains a maximum in the 3 4-position. The unsaturated phenyl groups in triphenylcarbinol occupy the 3 $-position with respect to the oxygen atom which therefore is very mobile and readily separates from the molecule in the form of hydroxyl (C=C)*C*O*H. In order to ascertain the effect of substituting sulphur in place of oxygen in the above system the nut,hors have examined the behaviour of triphenylcarbinyl- 4 - 2 1 4 70 2mercaptsn and find that in accordance with the above rule it shows a marked tendency to rupture between the sulphur and central carbon atoms.I t s acid properties are scarcely more pronounced than those of hydrogen sulphide or methyl mercaptan. It dissolves in alkali hydroxide9 but the salts thus formed are readily hydrolysed by water. I t comparison with other thio-alcohols i t shows a marked tendency to lose the thiol group. On treatment with concentrated sulphuric acid or perchloric acid it evolves hydrogen sulphide and is transformed into triphenylcarbinol. A similar decomposition occurs when the thiocarbinol is heated with acetic acid or acetic anhydride. With hydrogen chloride in benzene solntion i t yields hydrogen sulphide and o-chlorotriphenylmethane.When boiled with dilute aqueous alkali hydroxides i t slowly forms the corresponding alkali sulphides. The behaviour towards silver salts is very characteristic. It instantly reacts with silver nitrate in alcoholic solution yielding silver sulphide and triphenylcarbinol ; i n this respect i t resembles the hydrosulphides of the alkali-metals or metals of the alkaline earths. With silver perchlorate in benzene solution it forms silver sulphide and triphenylmethyl perchlorate. The benzoyl and acetyl derivatives and also the methyl ether resemble the parent substance in being readily ruptured between the sulphur and central carbon atoms. Thus the methyl ether on treatment with alcoholic silver nitrate yields the silver salt of methyl mercaptan whilst with concentrated sulphuric acid or dilute hydro- chloric acid the mercaptan itself is produced ; with alcoholic silver nitrate the benzoyl derivative yields silver thiobenzoate.The readiness with which triphenylcarbinylmercaptan suffers rupture between the sulphur and central carbon atoms indicates that the union between these atoms is very similar to that between the chlorine and carbon atoms in o-cblorotriphenylniethane. On the other hand the union between the cyano-group and central carbon atom in triphenyl- acetonitrile is much more stable for this compound does not react with silver nitrate arid is unattacked by sulphnric or perchloric acids. A tternpts to prepare triphenylcarbinyl mercaptan and triphenpl- acetonitrile by the action of hydrogen sulphide and hydrogen cyanide on triphenylcarbinol were unsuccessful.By passing hydrogen sulphide into o-chlorotriphenylmethane a t I 20-160° triphenylmethane sulphur and hydrogen chloride were produced. Reduction of the thiocarbinol with sodium and alcohol yields triphenylmethane and sodium sulphide whilst the action of chlorine in carbon tetrachloride solution gives rise to o-chlorotriphenyl- methane. The behaviour of triphenylmethyl disulphide (CPh,),S has also been investigated. On treatment with perchloric acid It liberates hydrogen sulphide but not so readily as the thiocarbinol. It is transformed by chlorine into o-chlorotriphenylmethane.

Elektrochtnz. 1913 19,830-833).-Berl ( A 1904 i 282) showed that the electrolysis of fused organic salts led to results which differed from those obtained from the electrolysis of aqueous solutions of these salts. I n the case of the sodium salt of o-nitrobenzoic acid melted with its free acid the product was nitrobenzene and not 2 2'-dinitrodiphenyl as was expected.The author has electrolysed a 15% soiution of potassium o-nitrobenzoate in o-nitrobenzoic acid a t I6O.-17O0 usiug a small porous pot as anode vessel and a beaker as cathode vessel. The anode consisted of 6-7 crns. of platinum wire wound into a spiral and the cathode was a platinum foil 3 crns. x 7 ems. The electrolysis was carried out by a current of 5 amperes and 50 volts.

Mixed Diphenylacetic Anhydrides and their Decomposition.HERMANN STAUDINGER E. ANTHES and H. SCEINEIDER (Ber. 1913 46 3539-33551).-1t has been previously shown (Staudinger and Ott A. 1908 i 602) that anhydrides of malonic acid decompose when heated yielding carbon dioxide and ketens. The scope of this method of preparation is greatly limited by the difficulty of preparing such anhydrides and the authors have therefore investigated the behaviour of mixed anhydrides of malonic and other acids (compare Staudinger and Berezs A. 1909 i 83) which can be readily prepared by the action of ketens on malonic acid. The authors have prepared a series of mixed anhydrides by the action of diphenplketen on derivatives of malonic acid. These are stable well-crystallised substances which appear to be unimolecular and thus differ remarkably from the amorphous polymerisad dimethyl- and diethyl-malonic anhydrides (A.1908 i 939). An anhydride could not however be obtained from malonic acid itself decomposition occurring in this case at a low temperature with formation of diphenyl- acetic anhydride and brown resinous products. The action of heat on the mixed anhydrides causes a primary dissociation into diphenylacetic anhydride and the corresponding malonic anhydride ; the latter then loses carbon dioxide to yield tho keten. Dimethylketon and diethylketen can be obtained in thisi. 1 3 4 0 A HS'I'RAC'IS OF CHEMICAL PAPERS. manner from dimethyl- and diethyl-malonic diphenylacetic anhydrides respectively. I n the latter case however sniall quantities of diphenyl- keten are also produced.This is attributed t o the partial decom- position of diphenylacetic anhydride into diphenylketen and diphenyl- acetic acid the latter substance also uniting with a portion of the dietliylketen and thus reducing the yield of the latter. A similar second a1.y decomposition occurs quantitatively during the d eco m - position of benzylidenemalonic diphenylacetic anhydride so that the product of the reaction is diphenylketen instead of the expected benzylidoneketen whilst the desired ketens were also not obtained from isopropylidenemalonic diphenplacetic anhydride and dicbloro- malonic diphenylacetic anhydride. Ethylchloroketen on the other hand mas readily obtained from ethylchloromalonic diphenylacetic anhydride. The mixed anhydrides are prepared by the addition of diphenyl- keten to very concentrated solution or suspension of the malonic acid in absolute ether reaction being allowed to proceed in an atmosphere of carbon dioxide. After a period which depends on the derivative of malonic acid emplojed the mixed anhydride separates in the crystalline state.The m. p.'s of the products depend somewhat on the manner of heating. D imeth y lm alonic diphen y lo cetic anhydride C Me2( C0.0 CO CHP ti 2) 2 has m. p. 91" (decomp.). When heated a t the ordinary pressure i t yields only small qnantities of dimethjlketen ; when decomposed in B vacuum however the yield of the latter amounts to 50%. The liquid polymeric compound (Staudinger and Kiever A . 1997 j 424) of dimethylketen appears to be formed in small quantity whilst the residue conpiets of almost pure diyhenylacetic anhydride.Dietlrylmalowic diphenyLacetic anhydride m. p. 94" when heated in a vacuum gives a 64% yield of diethylketen; at a somewhat higher temperature diphenylkoten is evolved which is identified by conver- sion into di~henylacetanilide. Diphenylacetic anhydride is obtained by the action of diphenylketen on an ethereal solution of ethylmalonic acid. The products of the decomposition of ethylmalonic anhydride have not yet been investigated. Benz$lidenemalonic diphenplacetic anhydvide m. p. 103" is more stable than the preceding compounds. When heated to 180' in n vacuum i t yields diphenylketen. Cinnamic and diphenylacetic acids are obtained by saponification of the residue from the distillation.isoPropylidenemaZonic diphen3latcetic anhydride m. p. lolo decomFoses slowly at its melting point. When distilled in a vacuum i t yields diphenylketen ; the residue consists of dark brown pasty mass which is probably formed by the rapid polymerisation of the keten and subsequent decomposition of the polymerisation product. ~ i c h ~ o r o m a ~ o n i c diphenykctcetic anhydride m. p. 74" (decomp.) is an iinstable substance which slowly decomposes a t the ordinary tempera- ture. When heated i t yields more than the calculated quantity of carbon dioxide and a t a higher temperature evolves hydrogen chloride. Dichloroketen has not been isolated. EthpZcldoromalonic mid m. p. 101-102" is obtained by boiling an absoliite ethereal solution of ethylmalonic acid with sulphuryl chlorideORGANIC CHEMIS'CHY.i. 1341 (compare Conrad and Reinbach A 1902 i 529). It combines with dipheny lketen yielding ethylchlorornalonic diphenytacetic ccnhydTids m. p. 95-96" which when heated in a vacuum gives ethylchloroketen CEtC1C:O. The latter condenses at -SOo to yellow oily drops which in a few minutes become transformed into a white solid mass. Attempts to obtain the unpolymerised keten at - 180" were unsuc- cessful. I n ethereal solutions at -80° i t can only be preserved for a short time. The keten vapours dissolve in ether with R yellow colour but after a few seconds the solution becomes colourless and on removal of ether the keten remains as a glassy somewhat viscous mass which is no longer completely soluble in the solvent.The keten polymeride is soluble in carbon disulphide and melts indefinitely a t 84-86O. When heated i t decomposer completely evolving hydrogen chloride and probably chlorobutyryl chloride. Ethylchloroketen unites with aniline to form chlorobutyranilide. H. W Conversion of Triphenylmethyl into Triphenylacetic Acid. ALEXANDER I. GORSKI (J. Russ. Phys. Chem. Soc. 1913,45,1454-1460). -In consequence of the varying behaviour of heated and non-heated ethereal solutions of magnesium triphenylmethyl chloride towards aromatic aldehydes Schmidlin (A. 1906 i 392; 1907 i 26 601 ; 1908 i 239 ; this vol. i 50) assumes the existence of two isomeric organo-magnesium compounds of o-chlorotriphenylmethane a normal stable P-compound which gives P-benzopinacolin with benzaldehyde and a n unstable quinonoid a-compound which gives p-benzoyltri- pheny lmet hane.Tschitechibabin (A. 1907 i 1022) is however of the opinion that only one such organo-magnesium compound exists. Since the experimental results given by Schmidlin in support of his assumption were not obtained under the corditions in which the con- version of t h s a- into the P-compound actually occurs the author has investigated the reaction further. By passing dry carbon dioxide into a heated mixture of a benzene solution of triphenylmethyl and the etherate of magnesium iodide he has succeeded i n obtaining good yields of triphenylacetic acid and triphenylmethane ; decomposition of the products by means of water failed to give any appreciable amount of triphenylrnethyl peroxide. This result is regarded as evidence in favour of Tscliitschibabin's view that Schmidlin's a-compound is really a mixture of a n ethereal solution of triphenylmethyl with the etherate of magnesium chloride.T.

The red form however which decomposes a t 195' after previous softening is obtained when this crude product is crystallised from aqueous alcohol. From ethyl acetate chloroform or glacial acetic acid solution the yellow keto-form frequently separates in well defined rhombohedriz cryst,als usually mixed with the red needles. The mixed form is obtained from solutions of the crude product in benzene toluene or xylene in the form of thin orange-red needles which are stable and do not become yellow on drying.

MARCEL BACHSTEZ (Ber. 1913 46 3087-3089).-Since phthalylglycyl chloride decomposes when heated into carbon monoxide and chlorometbylphthalimide (Gabriel A. 1908 i l S l ) whilst a-phthaliminoisobutyryl chloride decomposes according to the scheme CsH402:N*C1RIe2*COCl -+ CO + HC1+ C,H,O,:N*Cble:CH (Gabriel A. 1911 i 982) the author has examined the action of heat on a-phthalylalanyl chloride (A. 1908 i 182) and has thereby obtained small quantities of vinylphthcclimide C,H,O,:N*CH CH rhombic plates m.p. 86'. Attempts to improve the yield by the addition of traces of zinc chloride or aluminium chloride were un- successful. The substance unites with bromine to form phthalirnino- a/3-dibromoethane needle? m. p. 123-1 2 4 O which rapidly decomposes when preserved in the presence of moisture. A further attempt was made to prepare vinylphthalimide by the abstraction of hydrobromic acid from p- bromoethylphthalimide (com- pare Johnson and Jones A. 1911 i 455) by the action of sodium phenoxide in alcoholic solution. Phenoxyethylphthalimide m. p. 129-130' (Schmidt A. 1890 372) was thereby obtained. Small quantities of vinylphthalimide were obtained by the action of phosphoric oxide on P-hydr oxyethylphthalimide (compare Gabriel A.1905 i 265). H. W. Toad Venom. HEINRICH WIELAND and FRIEDKICH Jos. WEIL (Uer. 1913 46 3315-3327).-Bufotalin the poisonous principle of the toad first isolated in a n amorphous condition by F m s t (A. 1902 i 446) has now been obtained i n the crystalline state. It has the composition C1DH2104 is faintly dextrorotatory and neutral in character. Alkali converts i t into the unsaturated bufotalic acid proving bufotalin to be a lactoue. The other two oxygen atoms are present as alcoholic hydroxyl groups. Concentrated hydrogen chloride i n the cold eliminates two molecules of water forming a pale yellow crystalline compound C',,H2,0 bufotalien. It takes up two atoms of hydrogen in presence of palladium black. Acetyl chloride in pyridine or warming with acetic anhydride converts bufotalin into a doubly acetylated ether one hydroxyl group in each molecule being acetylated and the two molecules united through oxygen.Treatment of this diacetyl ether with concentrated hydrochloric acid forms a yellow strongly unsaturated compound C,,H2a0,. The same compound is obtained on heating bufotalein with acetic anhydt ide which effects direct acetylation on the carbon. Acetic anhydride is added directly to the C:C complex from which acetic acid is subsequently eliminated.1. J 344 AESTKAC'TS OF CEEMICAL PAPERS During the conversion of diacetylbufotalin ether into acetyl bufotalin the bridge oxygen is first eliminated as water. The single molecules -C(OAc):CH- undergo rearrangement. t o a saturated diketone -CO*CHAc- which loses water to form the doubly unsaturated monoketone -CH:CH*CH:CAc-.The analogy between bufotalin C,,H,,(OH);CO,H and cholic acid C2,H,,(OH)3*C0,H,. is emphasised. The unsaturated derivatives of both groups give Liebermann's characteristic cholestol reaction with acetic anhydride and sulphuric acid. Rufotalin is not identical with bufagin C,,H,,O obtained from the tropical toad by Abel and Macht (A. 1912 ii 1193). Bz~Jotnlin has m. p. 148' (decomp.)

RICHARD MEYER and CASIMIR DUCZMAL (Ber. 1913 46 3366-3379).-Although the reaction of chloroacetic acid with alcohols and phenols producing ethers according to the equation R*OH + CH,Cl*CO,H = HC1+ OR*CH,*CO,H is a fairly general one i t is usurtlly understood that this reaction fails with salicylic acid. The authors find that the reaction can be effected with salicylic acid although less readily than with most other substances and indeed mere mention of this fact has already appeared (Bogisch Diss. Stuttgart lSS9) although it has not found its place in the usual literature. The behaviour of the isomeric hydroxybenzoic acids and of the nit rophenola towards cbloroacetic acid is also investigated.The most satisfactory procedure for the reaction with salicylic acid is to dissolve equimolecular quantities of this Rubstance and chloro- acetic acid in a concentrated solution of a termolecular quantity of sodium hydroxide. The sodium salt of o-carboxypheooxyacetk acid separates and the reaction can be completed by heating for some hours on a water-bath. Any salicylic acid in the liberated acid product cnn be removed by extraction with ether. The yield of o-carboxyphenoxyacetic acid C0,H*C,H4*O*CH2*C02H m. p. 190-192" calculated on the salicylic acid consumed amounts to approximately m-Hydroxybenzoic acid dissolved in sodium hydroxide solution of 35% strength when gradually treated with chloroacetic acid gave rise to m-carboxyphenoxyacetic acid m.p. 206 -207". When equimolecular quantities of ethyl chloroacetate and sodium m-hydroxybenzoate are heated together in a sealed tube a t 170' for thirty hours elhyl m-hydroxy6enzoyloxyacetate is obtained as a viscous oil which can be hydrolysed by sodium hydroxide solution at 3' to m-h~cJrozybi?tsoylQ~~~cetl'c acid C'0,H.CH2*01C0.C',H,.0H 80%.OIlQANIC CHEMIS'rRY i. 1345 prisms m. p. 138-140*. On warming with sodium hydroxide solution it is hydrolysed to m-bydroxybenzoic acid. When treated in boiling sodium hydroxide solution (35%) with a n equimolecular quantity of chloroacetic acid p-hydroxybenzoic acid is conveI ted into p-carboxyphenoxyacetic acid m.p. 278'. The action of ethyl chloroacetate on sodium p-hydroxybenzoate is similar to t'he meta-compound and requires similar conditions ; the product is a n oily ethyl ester which on hydrolysis with cooled sodium hydroxide solution yields p-hydroxybenxoyloxyacetic acid CO,H~CH,*O~CO*C,H;OH silky needles m. p. 1'74-175'. o-Cresotic acid when treated in sodium hydroxide solution with chloroacetic acid produces 3-carboxy-o-tolyloxycccetic acid needles m. p. 203-204O. I n a similar manner m-cresotic acid gives rise to 4-ca~boxy-m-tolyloxyacetic m i d nodular aggregates m.. p. 164-165' whilst the p-cresotic acid yields 3-cc~rboxy-p-tolyloxyacetzc ncicl leaflets m. p. 185O. 1 2- and 2 3-Hydroxynaphthoic acids were likewise applied to this synthetic reaction sufficient sodium hydroxide beiDg used to just neutralise the acid reagents.The former acid gave rise to 2-carboxy- 1-ncphthoxgacetic acid silky needles m. p. 206-307' whilst the 2 3-isomeride produced 3-cu~boxy-2-naphthoxyacetic acid leaflets m. p. 224-225'. Chloroacetic acid acts quite normally on the sodium salt of 2:4-dinitrophenol but as the product is rather unstable excess ol alkali must be avoided ; the resulting 2 4-dinitrophenoxyacetic acid had m. p. 147-148'. No success attended attempts to obtain a condensation product of chloroacetic acid with picric acid even when the latter was applied as the silver salt ; as free picric acid and silver chloride were produced it is probable that the primary product underwent immediate decomposition I n all the above cases especial attention was given to the yields of the products and although the interaction of 0- and p-nitrophenols with chloroacetic acid had already been investigated experiments mere performed to determine the yields ; m-nitrophenol was found to behave similarly to the others producing 3- nitrophenozyacetic acid needles m.p. 154-155'. None of the above substances 'gives a quantitative result; it is found that the ortho-compounds give by far the poorest yields and the difficulty of reaction observed with salicylic acid is evidently to be attributed to its ortho-configuration. With the meta- and pars- compounds the yields are much better the para-compounds being the more satisfactory. D. F. T.

The mother liquor from which the trimethyl ether has separated contains the sodium salt of the dimethyl ether (formula 11) and this substance is deposited as the hydrochloride on the addition of Concentrated hydrochloric acid ; the free ethor is liberated from its hydrochloride by the action of sodium acetate solution.This dimethyl ether m. p. 2'i0-271° crystallises from methyl alcohol in reddish- brown prisms containing lAleOH ; i t dissolves in sodium hydrogen carbonate eolution giving the sodium carboxylic salt as R ye110 wish- red solution with a green fluorescence ; addition of sodium hydroxido solution causes the formation of the disodiurn ~ a l t with an increase of the fluorescencs ; silver salt insoluble reddish-brown precipitate.

I n the case of derivatives of fluorescein with which von Liebig obtained results a t variance with those of the author and his collaborators the substances have been reinvestigated with entire confirmation of the earlier results. It has already been stated by Fischer and Hepp (A. 1895 i 291) that the quinonoid dimethyl ether of fluorescein crystallises in two forms namely orange-yellow needles and deep red prisms. The difference in the m. p.'s recorded by von L'ebig and by Kehrmann and Dengler (A 1909 i 249) is due to this dimorphism. Indeed if a quantity of the orange-yellow needles is heated rapidly to 180° i t melts momentarily and resolidifies to melt again at approximately 194' ; under similar treatment the red prisms melt at 208'.The substance m. p. 255O obtained by von Liebig by the action of ammonia solution on the ether-insoluble residue (correctly regarded as trimethylff uorescein chloride) from tho reaction product of methyl sulphate and disodium fluorescein is not a dimethyl ether of fluorescein but contains almost 2% of nitrogen and probably represents it carbinylimide or B carboxylimide.

N. H. J. M. The Autoxidation of Organic Compounds. I. Autoxidation of Aromatic Aldehydes. HERMANN STAUDINGER [with E. HENE and J. PRODROM (Rep. 1913 46 3530-3535),-lt has been previously shown (A. 1911 i 877) that diphenylketen reacts more readily with methoxy- or dimethylamino-substituted aromatic compounds than with the unsubstituted substances and similar observations have been made during experiments on the action of oxalyl chloride on carbonyl com- pounds (A.1909 i 905). The authors have therefore been led to the determination of the rate of autoxidation of benzaldehyde and a number of its p-substituted derivatives. Weighed quantities of benzaldehyde p-methoxybenzaldehyde p-hydroxybenzaldehyde and p-dimethylaminobenzaldehyde were heated with an excess of oxygen in closed flasks a t 1 3 1 O and the amount of oxygen absorbed was estimated. In a second series of experiments a regular stream of oxygen was bubbled through the aldehyde the course of the reaction being followed by estimation of the acid formed. A t 13 lo however dimethylaminobenzoic acid readily evolved carbon dioxide; a temperature of 80’ was found suitable. The results show that p-dimethylaminobenzaldehyde is much less autoxidisable than anisaldehyde which however is less affected than benzaldehyde.This is inexplicable on Engler and Weiesberg’s hypothesis that the primary product during autoxidation is formed by the addition OF a molecule of oxygen to the unsaturated carbonyl group ; it is however to be expected if Baeger and Villiger’s supposition is adopted that the addition of the oxygen molecule is accompanied by dissociation of the hydrogen atom Ph*CKH 0 + 0.0 -+ Ph-C<,.,. 0 (A. 1900 i 437).i. 1354 ABSTRACTS OF CECEMICAL PAPERS. If Staudinger's views as to the asymmetric nature of the inter- mediate compound are accepted the bydrogen atom would be more firmly attached to the strongly unsaturated carbonyl group of p-dimethylaminobenzsldehyde than to the relatively saturated carbonyl group of beLzildehyde and therefore less capable of addition to the oxygen molecule.Prom this point of view o-mathoxybenz- aldehyde should be the least readily and m-methoxybenzaldehyde the most readily autoxidiszble of tlie three methoxybenzaldehydes and this is shown to be actually the case. Anti-auxochrome groups weaken the unsaturated character of the csrboriyl group and should therefore increase the mobility of the hydrogen atom and the tendency of the substance to autoxidation. p-Nitrobenzaldehyde which should thus be readily autoxidised absorbs little oxygen since i t is speedily resinified. The problem was how- ever investigated by the introduction of acyl groups into amino- and hydroxy-groups. Acetoxg benzaldehyde in contrast with hydroxy- and uiethoxy-benzeldehyde was found to be almost as readily autoxidised as benzaldehyde.H. W. The Autoxidation of Organic Compounds. 11. Relation- ships be tween Autoxidation and Benzoin Formation. HERNASN STAUDINGER [with E. HENE] (Ber. 1913 46 3535-3538). -If the possibility of formation of intermediate products be dis- regarded the formation of benzoin derivatives from aldehydes is comparable with the autovidation of the latter substances; in the one case addition of the aldehyde t o the carbonyl group occurs in the other to the oxygen molecule (compare preceding abstract). A benzoin will only be readily produced therefore from an aldehyde which con- tains a relatively unsaturated csrbonyl group and a relatively mobile hydrogen atom ; thus dimethplarninobenzaldehyde does not yield R benzoin since although the carbonyl group is strongly unsaturated the hydrogen atom lacks mobility.Favourable conditions for benzoin formation are found in benzaldehyde suisaldehyde and p-chlorobenz- aldehyde (compare Hantzsch and Glover A. 1907 i 538). From this point of view mixed benzoin derivatives should be obtainable from a pair of aldehydes if the one possesses rz sufficiently mobile hydrogen atom the other a sufficiently unsaturateJ carbonyl group; the con- densation products of p-dimethylnminobenzsldehyde and p-chloro- benzaldehyde with benzaldehyde ar3 described. p - DimethyZarninobenxoin NMe,*C6 €I,*CH(OH)*COPh m. p. 163-164' is obtained in 86% yield when a solution of benzaldehyde and p-dimethylaminobeuzaldehyde in alcohol is boiled with an aqueous sollition of potassium cyanide.The constitution of this substance is deduced from tlie fact that i t condenses with dimethylaniline in the presence of phosphorg 1 chloride to yield benxoyltetraniethyldiaminodi- phenylmethane COPh*CH (C,H,*NMe,) palo yellow needles m. p. 162-164' which are xeadily oxidiseti to n blue dye.

Polychromic Salts of Oximino-ketones.ISRAEL LIFSCHITZ ( B e y . 1913 46 3233 -3250).-Additional information as to the constitution of chromoisornerides is given by the study of the electrical conductivity of polychromic salt solutions. Oxiniinodimethyldihydro- resorcinol C M e < ~ ~ ~ ~ ~ > C N * O H has been studied as a more simple oximinoketone than violuric acid which contains nitrogen in the ring. I n addition to red and blue i t forms deep green alkali salts indicating that neither the third CO group nor the ring nitrogen in violuric acid are the cause of polychromism. The ring structure is however of importance since oximinoacetylacetone (CHI,*CO),C:N*OH only forms orange to red salts and polychromic forms of the same salt do not exist. Moreover these coloured salts are unstable.Ring structure alone does not cause polychromism as neither fluorenoneoxime benzo phenoneoxime benziloxirne nor oximinodibenzoylmethane exhibit the phenomenon. When the cornflower-blue plates of sodium dimethylviolanate are The came dimethylviolanic acid is suggested for it.i. 1362 ABSTRACTS OF CHEMICAL PAPERS dissolved in methyl alcohol the solution likewise cornflower-blue changes more or less quickly to bluish-green and then to a deep green when the crystalline green chromoisomeride may be obtdined from the solution. A t the intermediate stage it is possible to prepare crystal- line bluish-green o r greenish-blue mixed salts. All the5e solutions contain unimolecular pa1 tly dissociated salt as proved by ebullioscopic measurements. The green solution is characterised by a new second absorption band in the visible part of the spectrum and belongs to a new series of chromoisomeric oximino-salts.The change is rapid only in dilute solutions which are sufficiently dissociated as it is retarded by additions which check tht! dissociation. The conductivity of the green isorneride is 2-3% less than that of the blue form. The two forms differ chemically tho green form being very readily decomposed. I n the case of oximinoacetylacetone the cmirim salb decomposes immediately the rubidium salt can be kept for a time and the potassium salt is relatively stable. The rate of decomposition like the depth of colour increases with the atomic weight of the metal. Conductivity measurements indicate that dimethylviolanic acid contains yellow oxime ions and has the structure whereas the blue sodium salt :s derived from a blue acid having - a higher dissociation constant and probably tlie nitrosoenol structure C M e 2 < ~ ~ ~ ~ ~ ~ @ G * N 0 .This result is in agreement with the optical behiviour. The behaviour of the blue potassium salt and the red lithium salt of diphenglvioluric acid in methyl alcohol and in acetone indicates that the red lithium salt in acetone contains an internal alkali complex salt whereas in the violet-red solution iu m6thyl alcohol this complex has decomposed. Probably the yellowish-red and violet salts are not mixed salts but their isomerism is not due to differences in partial valency. The copper-red magnesium dimethylviolanate forms a violet-red solution in water and a red solution of very low conductivity in organic solvents.The green sodium dimethylviolanate is considered to have the co>C.NO. structure CMe,CCH;.U(ONa) CH -- Dimethylviolaiiic acid is prepared as described by Haas (l'. 1906 89 189).

JULIUS VON BRAUN and G.KTRSCHBAUM (Rer. 1913 46 3041-3050). -3-Methyl-l 2 -diketohydrindene is readily obtained by the action of cold formaldehyde and hydrochloric acid on oximino-3-methyl- hydrindone (compare Perkin Roberts and Robinson T. 19 12 10 1 232). It strongly resembles isatin having a deep reddish-yellow colour giving the same indophenine reaction and dissolving in alkali CMe with a very intense b!uish-violet colour which is much more stable CMe /'\A than the corresponding coloration from isatin. Of the two possible l I C*ONa '\/\/ \)\ANa formulae (I. and 11.) for the sodium salt the authors are led to prefer (Ii) CO (1- ) (11.) since the great change in colour from red to bluish-violet is bett,er explained (especially in view of the fact that the salts of 2-methyldiketohydrindene which must have a structure similar to that of formula I are red) whilbt also the free diketone gives no coloration with ferric chloride and does not combine with bromine that is it has no tendency towards enolislttion of the usual type.With benzoyl chloride the sodium salt of 1 2-diketo-3-methyl- hydrinden e yields 1 2 -diketo-3 - bznzo yl- 3-meth ylhydrin- dene which is readily explained by 1 4-addition. I n R\H\co this light the authors are led to propose the annexed I formula for the bluish-violet salts of isatin prepared by \/\/ Heller (A. 1907 i 442) and find confirmation there- OoNa fore in the fact that all derivatives of isatin in which the carbongl group adjacent to the NH group is substituted and which themselves are red or brown yield blue solutions with alkali whilst derivatives in which the /3-carbonyl group is substituted yield yellow or brown solutions with alkali.3-Methyl-a-hydrindone b. p. 118-1 19'/11 mm. is obtained as a pale yellow oil wbich could not be caused to solidfy by the action of aluminium chloride on a solution of P-phenylbutyryl chloride in light petroleum.

Compare this vol. i 877).-Neither Meerson (A. 1888 713) nor Kehrmann (A 1895 i 151) succeeded in obtaining diacetyldi- imino-a-naphthol by the action of acetic anhydride and sodium acetate on di-imino-a-naphthol hydrochloride. The latter as the author has already pointed out (A 1911 i 308) crystallises with 2H,O which partly decomposes the diacetyl compound at the moment OF its formation ; the inaccuracy of Meerson's view that acetic anhydride plays a part in this decomposition is evident from the fact that diacetyldi-imino-a-naphthol may be crystallised from this solvent as from any other free from hydroxyl ions without undergoing any decomposition.Dicccetyld i-im~no-a-lza~l~t~~o~ C,,H,,O,N obtained by the action of H.

The latter (1 mol.) combines with diacetyldi-iminonaphthol (1 mol.) t o give the compound C,4H,,0,N,,C,,H90,N m. p. 178' (decomp.) described by Meerson (loc.czt.). Decomposition of diacetyldi-iminonaphthol by heating in aqueous alcoholic solution results in the formation of f0u.r parts of 2-acetylamino-1 4-naphthaquinone and 1 part of 4-acetylamino-1 2- naph thaquinone. The action of a glacial acetic acid solution of anilino on a solution of diacetyldi-iminonaphthol in 95% alcohol yields a mixture of the ordinary dianilide with a new anilide 2-acatyln,naino-4-piLenyEimino- 1 4-nuphtEuquinone C,,H,02N2 which cryatallises in yellowish-red needles or in red plates with marked metallic lustre m. p. 185'; by boiling acetic acid i t is decomposed quantitatively into aniline and acetylamino-1 4-naphthaquinone.

ThuP this new anilide like the deriv- atives of naphthaquinones already investigated shows a marked tendency to react in two directions.

CHRISTIAN SEER and OTTO DISCHENDORFER (Monutsh. 1913 34 1493-1502).-The p - and m-di-a-naphthoylbenzenes have been prepared by condensing terephthalyl chloride and isophthalyl chloride respectively with naphthalene in cold carbon disulphide solution by means of aluminium chloride.Since phthalyl chloride reacts in the unsymmetrical form and a-naphthoyl-o-benzoyl chloride will not react in the cold such a condensation could not be carried out for the ortho-isomeride. The latter was obtained however from a-naphthoyl-o-benzoic acid by Guyot and Vallette's method (A 1911 i 653).

The second patent states that if the heating in the reactions described previously is carried out for a few moments only in the presence of mercury (or its salts) that the sulphonic group is eliminated but the migration of the bromine atom does not occur; t,hus when sodium l-bromo-2-aminoanthraquinone-3-sulphonate (1 0 parts) is heated with 100 parts of sulphuric acid (66' Ee.) arid mercury sulphate (0.5 part) at 180" during three minutes it gives rise to 1-bromo-2-amino- anthraquinone which readily furnishes 2-amino-1-p-toluidinoa~ijthra- quinone with p-toluidine whilst 4-bromo-1-aminoanthraquinone- 2-sulphonic acid gives rise to 4-bromo-1-aminoanthraquinone.F.

Compare A. 1912 i 706).-Further experiments have shown that there is no lower limiting temperature as previously suggested below which vulcanisation does not take place. By extend- ing the period of observation it has been found that vulcanisation occurs at 50° and from experiments made at intervals of 5' between 50' and 75' the velocity of the vulcanisation process increases on the average in the ratio of 2-84 1 for a rise of temperature of 10'.The value of the temperature-coefficient lends support to the view that the vulcanisation process is a chemical change. From comparative experiments on the speed of the vulcanisationOBOANIC CHEMISTRY. i. 1371 of caoutchouc gutta-percha and balata at 135O it appears that the rate of the change is practically the same in all three cases. I n each case also the vulcanisation reashes a limit when the quantity of sulphur non-extractable with acetone amounts to 32%. This pro- portion of sulphur corresponds with the formula (CIOHISSZ)n and it is supposed that this compound is formed from each of the three substances. The difference between caoutchouc gutta-percha and balata is con- sidered to have its origin in differences in the colloidal condition of the hydrocarbon the close similarity in the behaviour on vulcanisation being entirely opposed t o the view that the differences are chemical in nature.H. M. D. Formation of the Anthocyan Pigments of Plants. VI. FREDERICK KEEBLE E. FRANKLAND ARMSTRONG and W. NEILSON JONES (Pros. Roy Soc. 1913 B 87 11:3-131. Compare A 1912 ii 673 ; this vol. 1,325 803).-The pale yellow s i p colour of the petals of the wallflower is a mixture of hydroxyflavone glucoside3 (compare A. G. Perkin T. 1896 1566; Perkin and Pilgrim T. 1898 267). The mixture is hydrolysed by heating with acids and more slowly by emulsin. The hydrolyaed pigment if reduced and subsequently oxidised yields a red pigment. A red pigment is obtained from most flowers containing similar soluble yellow pigments suggesting that red mutations should be of possible occurrence in such species.Oxidation by oxydase of the hydrolysed products of glucosides in presence of amino-acids yields pigments. Arbutin for example yields a red pigment probably produced by the interaction of quinhydrone with ammonia. It is suggested that many of the pigments and odorous substances formed during the ripening of fruits arise as results of reactions of this type. A competition for oxydase ensues when a mixture of phenols is treated with a plant oxydase. Quinol monomethyl ether gives no colour reaction with oxydase but when a little beuzidine solution is added a deep and persistent carmine colour is obtained. The benzidine acts catalytically playing the part of a n organic peroxide and bringing about the oxidation of a substance which resists the action of oxydase and hydrogen peroxide.It is suggested that the higher members of a flower colour series owe their origin to the presence of specific substances which acting as receivers of oxygen reduce the pigments characteristic of the lower members of the colour series accept oxygen therefrom and become oxidised to pigments of speci6c colour. E. F. A. Anthocyanins. I. Pigment of Cornflowers. RICHARD WILL- ST~TTER and ARTHUR E. EVEREST (Annalen 1923,401 189-232)- Since Morot in 1849 and Frhmy and Cloez in 1854 isolated in an impure state the blue pigment of the cornflower very little work has been recorded probably on account of the instability of the antho- cynnin. An important observation by Molisch (Bot.Zeit. 1905 63 145) that in the flowers and red leaves of many plants the anthocyanin occurs not merely in solution in the cell juice but also in the crystal-i. 1372 ABSTRACTS OF CHEMICAL PAPERS. line or amorphous state revived interest in the subject and observa- tions many of which are erroneous have been recorded by Grafe by Glan by Griffiths (A 1904 i 179) and by Combcs (A 1911 ii 1125). Anthocyanins are the blue violet and red pigments which are extracted from flowers fruits and many leaves by water or aqueous alcohol and are inkoluble in ether; they are roughly classified by their colour reactions in acid and in alkaline solution and with lead acetate. For the sake of completeness it may be recalled that red and blue flowers also contain yellow pigments anthoxanthiw which are soluble in water or dilute alcohol and are quite different from the chemically indifferent carotins.The blue pigment of the cornflower is unstable and very difficult to isolate and has not. yet been obtained crystalline. The various shades of colour in different parts of the flower are due to various derivatives of one substance. Thus the blue pigment is the potassium salt of a n acid (cyanin) the violet pigment is the free acid and the red pigments are oxonium salts of cyanin and plant-acids. I n addition a colourless substance can be isolated from the flowers which is an isomeride of cyanin and is acid and forms colourless alkali salts. All anthocyanins are present in flowers as glucosides and not as previously stated by Grafe partly in combination with dextrose and partly not'.They all exhibit a characteristic reaction the antho- cyanidin reaction ; an anthocyanin dissolved in N- or 2N-sulphuric acid is quite unaffected by shaking with amyl alcohol but after hydrolysis on the water-bath the coloured fission product (antho- cyanidin) is quantitatively extracted by the alcohol forming a reddish- violet solution which is ehmged to bluish-violet by washing or more rapidly by eodium acetate. (In this connexion Erdmann's test for new or comparatively new red wine is discussed.) In order t o isolate the colouring matter dried cornflower meal mixed with six parts of sand to facilitate filtration is rapidly extracted with water or 20% alcohol preferably in the presence of sodium nitrate or chloride to retard the change of the anthocyanin to the colourless modification.The deep blue solution is treated with alcohol and the potassium cyanin after repeated fractional pre- cipitation with water and alcohol is obtained mixed with at least twice the weight of carbohydrates albumins and pentosans. In its further purification the blue pigment is treated with alcohol and hydrochloric acid whereby the pentosans (one of which is probably xylan) are precipitated and the pigment is converted in cyanin chloride C!28H3301,Cl 3H,O m p. 203-204' (corr.) (anhydrous) dark blue rhombic leaflets with golden reflex. The chloride is extremely hygroscopic aEd forms stable red solutions in acids; its aqueous solution rapidly becomes colourless but recovers its red colour by the addition of a n acid.A solution of the chloride becomes violet in the presence of calcium carbonate and changes from red through violet to cornflower blue by treatment with sodium carbonate. By hydrolysis with boiling 20% hydrochloric acid for three to three and a half-minutes cyanin chloride yields dextrose (2 mals.) and cyanidin chloride C,H,,O,CI long brownish-red metallic needles,ORGANIC CHEMISTRY i. 1373 which decomposes by slow heating but has m. p. 220' (decomp.) when placed directly in a bath a t this temperature. Like cyanin chloride cyanidin chloride is converted by aqueous sodium carbonate firstly into a violet solution of the acid cyanidin and then into a blue solution of sodium cyanidin. Moreover cyanidin chloride in dilute alcohol at 85' is slowly converted into an isomeride colourless crystals which is reconverted into red cyanidin salts by boiling dilute mineral acids; by prolonged keeping of its aqueous alcoholic or ethereal solution the colourless isomeride changes to another sub- stance colourless needles from which the red cyanidin salts cannot be regenerated.Little can be stated a t present with regard to the constitutions of cyanin and cyanidin The fact that the two substances form very stable salts with hydrochloric acid indicates that cyanin and cyanidin are related to benzopyronium (Decker and Fellenberg A. 1909 i 116) rather than to the flavones. c. 5.

Fur this purpose an apparatus is described which consists essentially of a cylinder and bulb connected by a tap the cylinder being also fitted with an inlet tube and a ground-on cap. The suspension of platinum in glacial acetic acid was saturated with hydrogen in the bulb the solution of the alcohol was then mashed with hydrogen in the cylinder and finally the two liquids were shaken together under a slightly increased pressure.

MAILLARD (Compt. rend. 191 3 157 850-852).-The humic substances obtained by the condensation of sugars with different amino-acids (compare A. 1912 i 169) readily yield cyclic bases when heated. The author applies this to the formation of coal from the constituents of cellulose and proteins and to its distillation yielding coal-tar containing pyridine and other cyclic bases. w. G. Allylpyrroles. KURT HESS (Ber. 1913,46 3125-3129).-When magnesium pjrryl bromide is treated with allyl bromide a mixture of approximately equal quantities of 2-allyl- and 2 5-diallyl-pyrroles is obtained. The formation of the latter compound is explained by assuming that some magnesium pyrryl bromide reacts with 2-allyl- p yrrole forming py rrole and 5 -magnesium-2-allplpyr ry 1 bromide which then unites with more allyl bromide. This view is supported by the fact that carbon dioxide converts the reaction product of 2-allylpyrrole and magnesium pyrrgl bromide into 2-allylpyrryl-5-carboxylic acid acid from which it follows that allylpyrrole is more acidic than pyrrole.The reaction between allyl bromide and magnesium pyrryl bromidei. 1380 ABSTRACTS OF CHEMICAL PAPERS. was vigorous but was not moderated by cooling. lation and extraction with ether %a,bZyZpyrrole After steam distil- CH*TH C H q ~ ~ c -CH,~XCH; was obtained as a colourless mobile liquid b.p. 82-83O/24 mm.

MOORE (Amer. Chenz. J. 1913 50 218-231).-1n order to investigate the formation of compounds of cobalt chloride with pyridine of crystallisation R study has been made of this system by the solubility method at temperatures between - 50.3' and 100". The results show the existence of three distinct cry- stalline compounds CoC1,,2C,H5N ; CoC1,,4C5H,N and CoCI,,GC,H,N. The first two of these have been isolated previously by Reitzenstein (A 1895 i 121). The compound CoCi,,2C,H5N has m. p. 196-200" but the m. p.'s of the other two compounds cannot be ascertained as they rapidly lose pyridine when heated under the ordinary pressure. The compound CoCI,,6C,H5N exists as the solid phase between - 50.3" and 15" CoC1,,4C,H5N between 15" and 70" CoC1,,2C,H5N between 70" and 90° whilst between 90" and the b.p. of the saturated solution CoCl is the stable solid phase. The usual methods of estimating cobalt are qot satisfactory in presence of pyridine and the following method was therefore devised. The weighed sample of solution was heated a t 120" until all the pyridine had been removed. It was then dissolved in 50% alcohol and an excess of oxalic acid was added to the solution. The precipitated cobalt oxalate was washed with 50% alcohol dried at loo" and dissolved in sulphuric acid (1 :3). The solution was diluted to 300 c.c. heated nearly to boiling and titrated with potassium permanganate. This method was found t o be very accurate. E. G. Cyclic Imines. VIII.

Ethyl nzssoxalale bisphenylisooxaaolone [Bis-3-p~enyZisooxazololze-4- malonate] m. p. 187' (decornp.) forms large octahedra by slow evaporation of its solutions or small prismatic crystals from acetic acid or boiling alcohol; i t is soluble in alkalis and can be titrated 1 mol.requiring 2 mols. of alkali to produce neutrality in presence of phenolphthalein. The sodium satt is crystalline and hygroscopic ; those of the heavy metals are colourless and amorphous; ferric chloride gives a violet precipitate. The sodium salt with ethyl iodide furnishes the diethyl ether m. p. 200-201° crystalking in silky slender needles. The diucetyl derivative m. p. 165-166" forms small prismatic crystals and the dibenaoyl derivative m. p. 194" colourless leaflet8 or stellate gr-oups of prismatic needies. Cryoscopic determinations of the molecular weight of the latter gave abnormal results. With benzenediazonium chloride ethyl bis-3-phenylisooxazolone-4-malonate gave benzeneazo- phen y lisooxazolone. T. A. H. The Constitution of Dinitrothiodiphenylamine [Dinitro- phenthiazine].FRTEDRICE EEHRMANN and FERD. RINGER ( Bw. 1913 46 3014-3020. Compare Mohlau Beyschlag and Kohres A 1912 i 212).-The authors believe that the dinitrophenthiazine obtained by Mohlau and his collaborators (Zoc. cit.) by the condensation of picryl chloride with o-benzoylaminopheny 1 mercaptan and subsequent treatment with sodium hydroxide solution is actually identical with and not an isomeride of the 3 5-dinitrophenthiazine described by Kehrmann and Schild (A. 1900 i 61). I n spite of the presence of the benzoyl radicle the picryl chloride must therefore have made the amino-group and not the mercaptan group its maiu point of attack. I n the action of picryl chloride on free aminophenyl mercaptan as well as on its benzoyl derivative however by-products are obtained which probably ropresent the isomerides of the main products and have the picryl radicle attached a t the sulphur atom The compound golden-yellow prisws m.p. 169" which is the main product of the interaction of picryl chloride and o-benzoylaminophenyl mercaptan is therefore considered to have the structure SH*C6H,*NBz*C,H,(N02)3 that is benzo-2 4 6-trinitro-2'-thio2diphenylamide whilst the substance orange-yellow leafy crystals m. p. 142" which results in smaller quantity is probably the true trinitrophenyl o-benzoylaminophenyl sulphide.

The substance described by Mijhlau as 2 4-diaminophenazthionium ferrichloride (Zoc. cit.) is in reality the ferrichloride of 3 5-diamino- phenazthionium the experimental conditions deciding whether the ferrichloride or merely the chloride (Kehrmann and Schild Zoc. cit.) shall separate.

HEINRICH WIELAND [with CARL MULLER] ( B e y . 1913 46 3296-3303).-Tbe blue coloration formed in sulphuric acid solutions of diphenylamine by oxidising agents was considered to be an acid sulphate of diphenyl dihydro- phenazonium. Eohrmann and Alicewicz (A. 1912 i 1020) have shown that it is more probably a quinonoid derivative of diphenylbenzidine PhN:C,H,:C,H4:NHPh*O*S03H. This explana- tion is now accepted although it is not applicable to the colour reactions obtained with diphenylhydrazine diphenylhydroxylamine and p-dianisylamine.Diphenylamine in dilute sulphuric acid and acetic acid solution is readily oxidised t o the blue dye which is easily reduced without the formation of by-products to diphenylbenzidine. Tetramethyl- hydrazine gives only small quantities of diphenylbenzidine a8 well as amorphous products ; its formation cannot therefore be regarded as an intermediate stage in the colour reaction. Triphenylamine shows a similar blue coloration on oxidation when quinonoid salts of tetraphenylbenzidine are formed. Tetraphenyl- benxidine crystallises in pale yellow needles m. p. 2 2 6 O to a brownish- yellow liquid. s-Diphenyl-o-pheny Zenediamine C,H,(NHPh) obtained by the action of iodobenzene and copper powder on o.aminodiphenylamjne crystallises as colourless double pyramids m.p. 152.5'.

XVII Diphenylhydroxylamine and Some Colour Reactions Related to the Blue Diphenyl- amine Reaction HEINRICH WIELAND and CARL MULLER (Bey. 1913 46 3304-3314).-Dipher1yIhydroxylsmine reacts with 75% sulphuric acid to form 70% of diphenylbenzidine together with a little diphenylamine and a green dye of high molecular complexity. The quinonoid-blue salt is formed in this instance by direct elimination of water from diphenylhydroxylamine. When the sulphuric acid is diluted with acetic acid instead of water the anhydro-product obtained is carbazole together with considerable quantities of p-hydroxydiphenyl- amine.Even ice-cold sulphuric acid converts diphenylhydrazine into diphenylhydroxylamine which is converted into diphenyl benzidine W. G. E F. A.ORGANIC CHEMISTRY. i. 1387 as described. Much ammonia is also formed also traces of o-amino- diphenylamine and some p-hydroxydiphenylamine. p-Tolylhydrazine and concentrated sulphuric acid give at first a bluish-green and green coloration due to hydroxylamine and ammonia is also formed. Further decomposition yields a yellowish-brown amorphous substance and much ditolylamine. Tetrapbenyl- and p-tetratolyl-hydrazine dissolve in sulphuric acid with a reddish-violet coloration which changes to blue. Diphenylamine and ditolylamine are also formed respectively.On oxidation of p-dianisylamine with persiilphate and sulphuric acid the salt OMe*C,H,~N:C,H,:OMe*O*SO,H is first formed but could not be isolated. A blue sulphate of the character of an indophenol which is red in solution was obtained ; i t very readily yields p-benzoquinone on treatment with dilute acids and is considered to be the acid suiphate of a polymerised bimolecular anisylqzcinone monoinzine HO*C,H,*N( C,H,*OMe) O,H,(OMe) N C,H,O.

The trihydrobromide obtained from the free base and alcoholic hydrogen bromide forms orange crystals The monohydrochloride of 3 6-diacetylaminoacridine forms slender yellow crystals. 3 6-Diumino- 1O-metiLylacridiniuna dihyclyochloride prepared by the action of methyl sulphate on 3 6-diacetylaminoacridine in nitrobenzene solution and subsequent hydrolysis of the resulting brownish-yellow methosulphate by means of hydrochloric acid forms dark brownish-red crystals of a metallic lustre and when warmed readily loses hydrogen chloride with the formation of the monohydrochloride.3 6-Biarnino-l O-methylacridinium bromide forms Bordcaux-red leaflets of a metallic lustre the-iodide orange needles and the nitrute reddish-brown needles. According to Kehrmann Havas and Grandmougin (this vol. i 1241) the green safranine salts formed by the combination of one molecule of the base with three equivalents of acid consist of a mixtuie of the yellow o-quinonoid salt I and the blue p-quinonoid salt I1 The diazotisation of safranine has also been studied.N- (1.) NH,X*C,H3~~~hX>C'H,.NH3X Of these two salts only the o-quinonoid foim should be capable of complete d iazot isn tion.ORGANIC CHEMISTRY. i. 1393 This view has been confirmed by the behaviour of phenosafranine which on treatment with solid sodium nitrite in concentrated sulphuric acid solution is partly converted into a bisdiazo-compound. If the solution is kept the p-quinonoid salt I1 is slowly transformed into the o-quinonoid form and then undergoes complete diazotisation. Reduction of the resulting solution by means of alcohol yields the phenylphenazonium of Kehrmann (A 1897 i 107). The Degradation of Allantoin to Hydroxonic Acid and a New Synthesis of Allantoin. HEINRICH BILTZ and ERHARD GIESLER (Brzr.1913 46 3410-3425).-Allantoin prepared from uric acid by oxidation with alkaline potassium permanganate solutioa was further oxidised to potassium allantoxanate ; by treating this in aqueous solution with slightly less than the calculated amount of N-sulphuric acid more than 90% of the theoretical quantity of allantoxaidtn (from decomposition of the unisolable allan toxanic acid F.

The above results indicate that allantoin is the amide of dihydro- allslntoxaoic acid but it was not found possible toconvert the esters of the latter substance into allantoin nor was it possible to obtain allmtoxanic acid directly from allantoin but the existence of the relations hip could be demonstrated in the following manner.When hydroxonic acid is boiled with acetic anhydride for eight hours i t undergoes loss of carbon dioxide with formation oE 1 3 6-tri- - acet y 2-5-umirnohydantoin (? o'NAc>CH*NHA~ tablets from acetone NAc-CO or prisms from benzene m. p. 184-185'; this substance when boiled with alcohol gives leaflets m. p. 240-241' of 1 6-diacutyZ-5-amir~o- hydantoin which on evaporation with concentrated hydrochloric acid is converted into 5-aminohydantoin hydrochloride m. p. 2 18-2 22"i. 1394 ABSTRACTS OF CHEMICAL PAPERS.

D. F. T. Ring Formation between the Nitro- and Amino-groups with Production of Triazines. FRITZ ARNUT (Bey. 1913 46 3522-3530).-The preparation and properties of a number of triazines are described which are obtained from o-nitrophenylguccnidine and o-nitro- phenylcarbamide by loss of water under the influence of sodium or potassium hydroxide. Since neither sodium carbonate ammonia nor acids bringabout this change it seems probable that ring formation is preceded by formation of the alkali salt of the $-nitro-form. This is the more likely since the originally orange-yellow solution becomes red when warmed with alkali and then yields a yellow precipitate.After ring formation the reverse change immediately occurs since the product obtained does not possess the properties of an o-quinone. If Angeli's formula for the azoxy-group (this vol. i 658) is adopted the compounds obtained by the author may be regarded as containing this group in the triazine ring and i t therefore seems to be produced with remarkable ease by loss of water from an amino- and nitro-group when ring formation can simultaneously occur. o-Nitrophenylguanidine nitrate pale yellow prisms m. p. 160° is obtained by the addition of 2N-nitric acid to the product of the action of concentrated hydrochloric acid on a mixture of o-nitroaniline and cyanamide.Should the latter contain dicysnamide the white amorphous nitrate of a condensation product of cyanamide and dicyanamide is also formed o-Nitrophenylguanidine NO,*C,H,*NH*C( :NH)*NH separates as a viscous oil when the finely powdered nitrate is treated with cold 2N-sodium hydroxide.

Sodium nitrite and hydrochloric acid convert 3-amino-1 2 4-benzo- triazine oxide directly into 3-hydroxy-l 2 4-benxotriazine 1 -oxzde yellow leaflets m. p. 219' (decomp.).

The latter substance is best obtained by the action of potassium ferricyanide and sodium hydroxide on a solution of dihydroaminophentriazine nitrate. For the preparation of o-nitrophenylcya~anzide NO,*C,H,*NH*CN an intimate mixture of o-nitroaniline hydrochloride and lead thio- cyanate is allowed to remain a t the ordinary temperature until a portion does not melt when placed in boiling water ; the mixture is then heated for six to seven hours on the water-bath and subsequently boiled with 2N-sodium hydroxide ; after removal of lead sulphide the solution is cooled filtered from unchanged o-nitroaniline and cautiously acidified with hydrochloric acid when o-nitrophenyl- cyanamide pale yellow needles m.p. 1 5 3 O separates in poor yield. Boiling dilute hydrochloric acid transforms it into o-nitrophenyl- carbamide yellow needles m. p. 183-184' (Schwartz [A. 1897 i 4111 gives lsl') which is converted by boiling potassium hydroxide into hydroxybenzotriazine oxide identical with the product obtained fram aminobenzotriazine oxide. Attempts to prepare o-nitrophenylthiocarbamide were unsuccessful. \/\/ H. W. A Mode of Decomposition of Halogenated Alkyl Deriv- atives of Hexarnethylenetetramine. MARCEL SOMMELET (Compt. ?.end. 1913 157 852-854. Compare Hock A. 1903 i 465).- Derivatives of hexamethylenetetramine of the type C,H1,N4RX where R is an alkyl group and X one of the halogens are decomposed by boiling with water. This is particularly true of the derivative obtained from benzyl chloride the products of the decomposition being benzaldehyde (7O-SO% yield) and a mixture of bases of which t h e following were characterised ammonia methylamine dimethy lamine trimethylamine and benzylamine.Benzaldehyde is similarly obtained by boiling benzyl chloride aud hexamethylenetetramine together in aqueous alcoholic solution.

Each of these are similarly decomposed by boiling with water giviug the corresponding tolualdehydee. The course of t h i s decomposition reaction is not yet clear but the relatively abundant production of methylamine points to the possible primary production of benzylmethgleneamine which undergoes isomerisation to beuzylidenemethylamine CH,Ph*N:CH2 -+ CHPh:NMe.w. a.i. 1396 ABSTRACTS OF CHEMICAL PAPERS. Anilinoquinones and their Azin e Derivatives. FRIEDRIC~ KEHRMANN and MARCELTEN CORDONE (Ber. 1913 46 3009-3014).- The authors have convinced themselves of the correctness of Will- stiitter's view as to the holoquinonoid nature of both modifications of o-benzoquinone but believe that these merely represent dimorphous forms of the same substance. o-Benzoyuinone is said to present a n example of dichroism on account of which the different crystalline forms appear t o be of different colours; the less stable form is stated to be not colourless but green.Both forme of the substance are therefore of diketonic structure. If catechol is oxidised in the presence of aniline by silver acetate in scjlution in cold acetic acid a brown mixture of 4 5-dianiliiao-o-beruo- quinone (annexed formula) bro wnish-red needles m. p. 193' with a little of the trianilino-compound separates ; the former is easily extracted by sodium hydroxide in which it is soluble.

Under siiiiilar conditions to the above 3-anilino-4-hydroxy-o-benzo- quitlone (Zincke A. 1885 787) condenses with o-phenylenediamine hydrochloride ; producing long deep red needles of the hydrochloride of 2-anilino-3-hydroxyphenazir~e ; the free bass forms brownish-red needles decomp. above 200'. Condensation with phenyl-o-diphenylenediamine gave rise to two products which are probably 3-anilino-2-hydroxy-10- phenylphenazonium chloride and 2-anilinoaposafranone The constitution of the above dianiliuo-o-benzoquinone is demon- strated by hydrolysis with dilute solutions of alkali which gives rise to the s-dihydroxyquinone of Nietzki and Schmidt (A.1888 1181). OF the three possible isomerides having the co:nposition of a dianilino- quinone two are already known so that t o this third isomeride is to be ascribed the remaining structure 4 5-dianilino-o-benzoquinone.

Wheu the rnethaeernogll~bin is brought into solution by means of hydrochloric acid or sodium hydroxide increased viscosity and diminished surface tension are shown by the liquid which is a t first a suspension solution and finally yields a perfect solution.Con- tinued addition of acid or alkali does riot lower the surface tension beyond a certain value which seems to be independent of the concen- tration of the dissolved wethaernoglobin so long as this lie3 within cei tain limits ; neutralisation of the acid (alkali) wit,h an equal volume of alkali (acid) causes precipitation of the methaemoglobin and increase of the surface tension. The increased velocity caused by hydrochloric acid diminishes considerably when exvess of acid is added aud tends to return to its original value although no precipitation occurs. This seems to be duo to the iufluencie of the acid in lowering the dissociat~on of the methamoglobin chloride and hence the conrleutration of the mothzmo- globin ion.on which the increased viscosity depends. Addition of sodium ctrloride to solution of sodiiirn methaemoglobinste produces a further sruall con+tant diminution in the surface tension although the salt has no appreciable effect on a sollition of pure metha3moglobin (compare Bottazzi and d’Agostino this vol. ii 115).

Some mercury compouuds of substituted naphthalenes are discussed and i t is shown how their unusual behaviour and incoustant composition may be explained by cousidering the residual affinities of the atoms and groups involved. When the sodium salt of 8-amino-1-naphthol-3 5-disulphonic acid (K-acid) is digested with mercuric acetate a bright red mercuriated substance is obtained. From its method of formation and its colour i t might be expected that the mercury is attached to a carbon atom but the fact that ammonium sulphide tames precipitation of mercuric sulphide suggests that the metai is linked with nitrogen. The colour was destroyed by the addition of alkali or sodium chloride but was reproduced on acidifying with a mineral acid. The varying mercury-content of the product suggested that not a chemica1,'but rather an adsorption compound was present but the fact that salt or strong acetic acid decolorised solutions of the substance is not in harmony with this view. The influence of various substituents in the naphthalene nucleus was studied and the following conclusions are drawn the presence of -OH or -NH in the P-position hinders the fixation of mercury only one atom of which enters the ortho-position; the presence of -OH or -NH in the a-position permits of the entry of two mercury atoms in t h e ortho- and para-positions giving compounds which are stable towards ammonium sulphide but tend to form unstable coloured quinonoid compounds in the preheuce of reagents which reduce the acidity of their soliitions; when attempts are made to introduce more mercury into naphthol derivatives alkali is found to remove the excess of ruercury as the hydrosol of the hydroxide but the naphthylamines can loosely fix more mercury giving substances which are turned deep red by alkalis and decomposed by ammonium sulphide ; sulphonic acid groups I ender the mercury cornpounds more unstable. I n K-acid the various effects indicated above are cumulative. These effects are discussed on theoreticd grounds and i t is explained why these naphthalene derivatives can form compounds with indefinite quantities of mercury in which there is no distinction between true chemical combination and adsorption.

i. 1402 ABSTRACTS OF CHEMICAL PAPERS. Physiological Chemistry Water in Expired Air. WILLIAM OSBORNE (Proc. physiol. Xoc. 1913 xii ; J. P/vysid. 47).-Gnleotati states that t h e expired air is not fully saturated with aqueous vapour b u t only about three- quarters saturated. Loewy and Gerhartz point out t h a t this is incori+ect for the temperature of expired air is not 3$" but between 32.5O aiid 33.5'. The present experiments confirm the latter view aiid the correct theoretical figures were obtained if thePHYSIOLOGICAL CEEMISTRP. i. 1403 temperature is assumed to be 3 3 * 9 O . The experiments were made on men in whom loss of water by the skin was prevented by a rubber suit. Such experiments are only safe in winter as a dangerous fever may arise if the external air is too warm.W. D. H. Acidosis. ICRNEST L. KENNAWAY l f AXCUS s. PEMBREY and EDWARD P. POULTON (Proc. p h ysiol. Soc. 19 13 x-xi ; J. Plysiol. 47).-In healthy men the value of the alveolar carbon dioxide pressure may fall below the normal (40 mm.) if carbohydrate food is withheld; in diabetes it may be normal; the determining factor is the extent of acidosis. It falls suddenly one o r two days before the onset of fatal coma; a value of 25 is grave; one of 20 means that coma is imminent. Estimation of the acetone substances is not such a good guide and suggestions are put forward to explain variations in the ratio between these substances. Their equilibrium point is probably connected with the degree of acidosis and the high pro- portion of @-hydroxybutyric acid in marked cases may be due t o a washing out of acetone from the blood by the increased pulmonary ventilation.W. D. H. The Carbon Dioxide and Oxygen Content of t h e Blood after Clamping the Abdominal Aorta and Inferior Vena Cava Below the Diaphragm. JOHN R. MURLIN LEO EDELMANN and B. KRAilrER (J. Biot?. Chem. 1913 16 79-101).-The changes fo1.ind are consist,ent with the mechanical explanation of the altered respiratory quotient after clamping the vessels. When the quotient rose the carbon dioxide of the blood fell; when i t remained stationary the carbon dioxide did not change; when it fell the carbon dioxide rose. Clamping off the blood from the abdominal organs therefore does not alter the character of the metabolism. W. D. H. The Dissociation of Carbon Dioxide from Human Blood.JOHANNE CHRISTTANSEN CLAUDE G . DOUGLAS and JOHN s. HALDANE (Prop. phvysiob. Soc. 1913 ii ; .I. Physiol. 47).-The experiments here briefly referred to show that the effect of oxygen on the carbon dioxide-carrying power of the blood is even more important than the well-known effect of carbon dioxide on its oxygen-carrying f UF ctions. W. D. H. The Combination of Hydrogen Arsenide in the Blood. RICHARD MEISSNER (Chew&. Zeiztr. 1913 ii. 705-706 ; from Zeitsch. expt. Path. They. 19 13 13 284-300).-The nbsorptim cd pzcity of the various constituents of blood for the gas was estimated by Reckleben and Lockemann's method. All solutions o r suspensions were shaken f o r the same period with the same amount of the arsenic compound. The various lipoids in suspension o r in ether and chlorof orrn solution have practically no combining capacity in quantities in which they occxr in the blood.Even the lxain can combine with no more hydrogen arsenide than can physiologicali. 1404 ABSTRACTS OF CHEMICAL PAPERS. saline in which it is suspendea. Of the other constituents haematin possesses a marked combir:ing capacity and blood containing carbon monoxide is less liaile LO haemolysis by the arsenic compound than normal blood. The combining capacity of the iron-free hEmatoporphyrin is much smaller than that of Iizeniatin. It appears that the iron plays some psrt in the combination of the various iron compounds investigated ; only sdiuin nitroprusside evinced any marked combining capacity €or it yielded with hydrogen arsenide a solid substar?ce containing both iron and arsenic.The antagonis- tic action of variou,s substances t o hydrogen arsenide poisoning was also investigated. Cholesterol and iodipin were witliout effect. Various colloidal silver and mercury preparations were also tried but although they combine with the arsenic compound they were too toxic t o the kidneys f o r i ! i f m vihm use. Of the other sub- stances investigated only cadmium chloride exhibited a high combining capacity. The in uitro action of the hydrogen arsenide on blood gives a product with a spectrum similar t o tliiomethaemo- globin. S. B. S. The Fermentative Properties of Blood. 11. The Peptolytic Ferments of Normal Animals. LUDWIG P i ~ c u s s o n ~ i3tId HELIA~UTH PETOW (Biochew.Xeitsch 19 13 56 3 1 %-329),-111 coutiriuatlori of the work of Pincussolm (this vol. i 78S) many examples are given t o illustrate the fact that the sera of animals are capable of degrading the peptones prepared (by sulphuric acid method) from the prcteins of their own organs but not from the organs of other animals and foreign proteins. An exception was found in the case of guinea-pig serum and attention is called t o the fact that this serum is used generally for supplying the complement in various hEmolytic systems. Guinea-pig’s serum also degrades silk peptone. The serum also degrades peptones prepared from the organ proteins of closely allied species. Thus the serum from the fox also degrades peptones prepared from the organs of dogs ant1 dog’s serum degrades peptones derived from fox tissues but not from those of any other animals.The method may therefore be applied for determining the relationship of various species. S. €3. s. Phosphatides of the Stromata of the Red Blood Corpuscles of Sheep and Man. 1.7. FUHGER and H. BEUJIKR (Biochn. &i/sch. 1913 56 446-456).-The stromata of sheep were precipitated by carbon dioxide from the lysed blood and dried. They yielded an ethereal extract which consisted t o the extent of 70% of cholesterol The residue after extraction with ether was partly soluble in alcohol a t 3 7 O Of the alcoholic extract part remained insoluble after treatment with ether. This was obtained in the form of a white powder of stearin-like consistency which swelled on treatment with water and had m.p. 180-185O. I t s analysis indicated CL di rtminoirionophoephatide similar in its properties t o the myelins. Of the ether-soluble portion of the alcoholic extract the greater part was precipitable by acetone and of the acetoneP€IYSIOLOOICAL CHEMISTRY. i. 1405 precipitate part was insoluble in h o t alcohol although soluble in ether and chloroforiii. This was a monophosphatide with the properties of a kephalin. The stromata of sheep’s corpuscles contain therefore about 5% cholesterol and 1296 phosphatides of which about half is sphingomyelin and kephalin is a constituent of the remainder. The blood of normal individuals and of carcinomatous individuals (drawn i n the latter case from the cadaver) was examined in a similar manner t o that employed in the case of sheep’s blood.No essential differences in the chemical composi- tion of the stromata of normal and cancerous individuals could he found the ethereal extract containing 71.6 and 74% of cholesterol and the alcoholic extracts 35 and 31:L of sphingomyelin. There was isolated in addition t o kephalin from the acetone pre- cipitate from human blood small quantities of a phosphatide with 3.3% phosphorus and 4.33% nitrogen which yielded a clear solution in water but was insoluble in hot alcohol and ether. Distribution of Ions in the Blood Serum. PETER RONA and PAUL GYORGY (Biocltem. Zeitsch. 1913 56. 41 6-438).-According to Zuntz and Hamburger part of the sodium of the serum is non- diffusible as it is in combination with the proteins. On treatment of the serum with carbon dioxide part of this sodium should be convertible into sodium hydrogen carbonate.If therefore serum treated with carbon dioxide is submitted to dialysis (by the com- pensation method repeatedly used by Rona) the outer liquid should contain more sodium hydrogen carbonate than the dialysate of a serum which has not been so treated. This was actually found to be the case and the results confirm the statements of Zuntz. The carbon dioxide should however convert the serum proteins into a carbamic acid derivative. There would therefore exist in the dialysor sodium salt of a non-diffusible acid. Attention is called to the fact that accord’ing to Donnan’s theory (A 1911 ii 848) axrived a t by thermodynamic considerations the amount of sodium hydrogen carbonhte on both siles of the dialysing membrane will not be the same when equilibrium is established for on one side there is an electrolytically dissociated substance with a non- dialysable ion.The sodium hydrogen carbonate in the dialysor could not be estimated in a satisfactory manner by incineration. The contents were therefore submitted to ultra-filtration in a Bechhold apparatus apd the filtrate v-as analysed. The distribution of the chlorine was also investigated when the [H’] concentration of the serum was altered by the addition of acetic acid. I n con- centration above H‘ = 10- 5 eqcilibrinm exists with a higher con- centration of chlorine inside than outside the membrane whereas in lower [H’] concentlrations the reverse is the case. The critical point of change i s the isoelectric point through which the protein changes from the anionic t o the cationic state.The Donnan theory is also applicable in this case to the determination of the distribu- tion of the chlorine.

The amount of salt necessary to prevent coagulation varied with the salt employed and the plasma obtained could be made to coagulate according to the kind and amount of salt used either by.dilution or by addition of a calcium salt o r by addition of serum. Magnesium chloride and sulphate are the most appropriate for the study of these phenomena since they do not precipitate calcium salts give no apparent reaction with the saline constituents of blood and for small differences in weight give different types of plasma.w. G. The Inactivation of Complement by Mechanical Agitation. HANS SCHMrDT (J. iipgiene 19113 13 291-313).-The complement in serum is inactivated by shaking. This does not seem t o be associated with the precipitation of protein which also occurs. No explanation of the inactivation is at present forthcoming. W. D. H. Complement Action i n Regard to Surface Tension. HANS SCHMIDT (J. Hygiene 191 3 13 314-334).-No relationship between the surface tension and complement action of serum was found. W. D. H. The Rate of Elimination of Nitrogen as Influenced by Diet Factors. I. The Influence of t h e Texture of the Diet LAFAYETTE 13.MENDEL and EOBERT C. LEWIS (J. Bid. Chem. 191 3 16 19-36).-A standard diet was arbitrarily selected f o r dogs and a constant curve of nitrogen elimination was obtained. This shows a rise reaching a maximum in the second three hours and then a fall to the initial level early the next day. Delay in elimination is caused by adding indigestible materials such as mineral oil vaselin bone ash paraffin filter paper cork agar-agar; the effect increases in the order these are enumerated. The last four cause a higher rate of elimination in the later periods. This is attributed to a slower rate of absorption which in its turn may be produced by (I) rapid emptying of the stoniach and a consequent early exclusion of gastric digestion ; (2) the indigestible material may make the digestible material less readily accessible t o digestive enzymes; or (3) the final digestion products may be adsorbed by the indigestible substances.Sand gives exceptional results ; i t causes more rapid elimination cf nitrogen during the first six hours. This is not due t o Jncreasecl excretion and reabsorption of digestive juices for in starvation it has n3 effect. W. D. H. The Rate of Elimination of Nitrogen as Influenced by Diet Factors. 11. The Influence of Fats and Carbohydrates i n t h e Diet. LAFAYETTE B. MFNDEL and ROBERT C. LEWIS (J. Bid. Chem. 1913 16 37-53).-Carbohydrates delay the elimination of nitrogen when added t o a protein meal; their effect increases in the order starch soluble starch sucrose dextrose.This may be explained hy the tentative suggestion that i t is due t o the protein-sparing action of carbohydrates. T n reference t o fats cottonseed oil delaysPHYSlOLOGICAL CHEMISTRY. i. 1407 the elimination of nitrogen but lard and “oleo-stearin” hasten it in the early periods. The last-named effect is however only due to removal of subrose from the diet. W. D. H. The Rate of Elimination of Nitrogen as Influenced by Diet Factors. 111. The Influence of the Character of the Xngested Protein. LAFAYETTE B. MENDEL and ROBERT C. LEWIS ( J . Bid. Cheni. 1913 16 55-77).-Extracted meat lowers the rate of nitrogen elimination ; the explanation advanced is that extracted meat contains relatively more connective tissue and therefore is not so digestible. The curves following the ingestion of caseinogen ovo- vitellin edestin “ glidine,” and gelatin show no more differences than those noted in the two meat products Egg-white or albumin and soy bean give different curves due t o rate of digestion and absorption or in the case of soy bean t o the presence of sucrose.Proteins do not differ materially in their rate of metabolism. The opposite findings of others are discussed. W. D. H. The Metabolism of Infants During Starvation. ARTEIUR SCHLOSSMAKN and HANS ~ ~ U R S C H H A U S E R [and in part KARL MATTISON] (Biochenz. Zeitsch. 191 3 56 355-415).-The authors in confirmation of their previous investigations show that the metabolism during starvation depends on the diet consumed in the period preceding the fast and that the more nitrogen consumed during the period the greater is the amount of body protein decomposed during the first two or three days of starvation.Similar results were obtained in the case of infants. The breast-fed children metabolise less nitrogen than the artificially fed. There is however a marked difference between the metabolism of the two classes during starvation for whereas the art!ficia,l!y fed children excrete less nitrogen during the period of fast than during the nutrition period the reverse is the case with the breast-fed infants. I n spite of this fact however the breast-fed children still excrete less nitrogen during the starvation period than the hand-fed children and the authors draw the conclusion that the former are more capable of resisting the effects of deprivation of food.The excretion of the acetone substances during starvatio ’L was also investigated. The amount excreted rapidly increased in the second day of hunger running noarly paralle! ~ i t h the increased output of nitrogen in the case of the breast-fed ch;ldren. I n the case of the hand-fed children the acetone substances increased with diminishing nitrogen output. A few measuremer‘ts of tho respiratory exchanges were also made by the authors. S. B. S.

P/l?/S70/. 1913 32 3.58-358) - Evidence is adduced that absorption of fats occurs in the stomach of mammals (cats dogs rats). The gastric epithelium contains fat even in fasting; this is increased by feeding on fats. The fat in the gland cells especially in the pyloric region may be increased by fasting.This has no relation t o absorption fat but is due t o mobilisation of the body fat. The observations throughout are histological. W. D. H. The Processes of Absorption in the Intestine. N. A . DOBROWOLBKAJA (Biochem. .Zei!sch 1913 56 267-290).-'l'he author discusses the various views as to the method of utilisation of the proteins in the organism including those of Heidenhain Hoff meister Abderhalden etc. and atteinpts by various experi- mental methods to throw some light on the mechanism. I n the first series of experiments he analyses the serum of portal blood of dogs estimating tlie changes of total non-protein nitrogen and the amino- and peptide-nitrogen produced by the introduction of the chymus obtained from intestinal fistulae of other animals into the small intestines.No definite results were obtainable by this method as i t was shown that the operative procedure alone without. introduction of digestion products produced changes in the com- position of the serum of the experimental animals. I n a second series of experiments the in vitro changes on the amino-nitrogen produced by serum intestinal extracts pancreas etc. on amino- acids and digestion product of proteins were investigated. The results again lead t o no definite conclusions in some cases indicating synthesis and in others peptide degradation. I n the third series of experiments an anastomosis was made between the portal vein and the kidneys by the junction of the central end of the vena Ziencrlis with the peripheral end of the renal artery.It was assumed that in the event of introduction of digestion products in the intestine and a consequent resorption of amino-acids into the portal vein the excess would be eliminated by the kidneys. To increase the pressure in the kidneys the portal vein was partly constricted above the junction with the v e m ZiencrZis. I n the majority of cases the kidney not connected with the portal vein was extirpated. I n all of these cases the animals died. I 1 1 two cases when the second kidney was left intact a certain number of experiments were per- formed an4 the nitrogen of :he amino-groups the hippuric acid and ammonia nitrogen of the urine excreted were estimated. The introduction of nitrogen into the alimentary tract (by feeding) lead in many cases especially that of alanine to an increased amino-xitrogen in the urine.Owing to the fact that the second kidney was intact these experiments could hardly be consideredPNYSIOLOGlCAL CHEMISTKY. i. 1409 satisfactory. I n the fourth series of experiments a portal vein fistula was made according t o the method of London and the author and blood was removed by way of the fistula at various periods after feeding. The results showed a periodic fluctuation in both the portal blood and the blood of the general circulation (removed from the jugular vein). The general result of the experi- ments is t o indicate the difficulty of artificially increasing the amino-nitrogen of the portal vein under conditions approaching the normal physiological. S. B. S. The Relation of the Necessary Substances to the Lipoid Extracting Agents.\ViIAImm S,rEPP (&it.&. BioZ. 1!!13 62 405-407 Compare A. 191 1 ii 1002).-Tliis is a continuation of the author’s previous work on mice. A mixture of lecithin cholesterol kephalin cerebron and phytin added t o a diet freed from lipoids by alcohol- ether extraction does not supply the missing necessary material. If the primary acetone extract of egg-yolk is added to lipoid-free food the result is that the ne:essary material is still lacking; the same is true for the secondary alcoholic extract. But the primary alcoholic extract restores the value of the lipoid-free food. The materials necessary for life ar3 therefore soluble in alcohol but not in acetone. I f the msterial is extracted with acetone first part only of the indispensq.ble material goes into solution ; the acetone- soluble substances are soluble also in alcohol.Extraction with ether does not remove the indispensable material ; fat is therefore f o r the mouse not indispenszble. Extraction of the food with alcohol entirely removes its power t o support life. W. D. H. Are there Substances at Present Unknown in Food-stuffs which are of Importmce for t h e Maintenance of Life? EUIL ABDEHHALDEN and ARNO E. LAMPI? (Chena. Zentr. 1913 ii 522-523 ; from Zeitsch. gesarnte. expt. Med. 19 13 1 296-354).-Xs a result of a critical experimental investigation on a broad basi,s of the work of Suzuki Shimamurs and Odake and of Funk and others the authors draw the concllusion that’ up to the present time there has been no absolute proof of the existence of unknown sub- stances in foods of general significance which are essential to the maintenance of life.They do not consider that the action of the so-called oryzanin of the Japanese authors or of Funk’s vitamine has as yet been definitely established. The Biological Significance of the Fat-content of Fish with Special Referenca t o their Habitat. Osw. POLIMANTI (Hiochm. Zeitsch. 1913 56 439-445).-Attention is called to the fact that during the development of fish embryos the amount of visible fat diminishes during which time the habitat gradually alters froni that of an organism living on the surface of the water t o one living deeper in the sea. It seemed therefore possible that the nectonic fish which move rapidly about the surface should contain more fat than the less active more slowly moving benthonic fish.Numerous analyses of various species were carried The Indispensability of Lipoids for Life. S. B. S.i. 1410 ABSTRACTS OF CHEMICAL PAPERS. out which tend to confirm the above theory the fat varying from 1.115 to 20.447% of the solid substance. Proteins of Fish Sperm. A LBRECHT KOSSEL (Zeitsch. plqsiol. Chem. 1913 88 163-185).-The protamines from the sperm of a number of species of fish have been isolated and investigated. (The figures given are % of total nitrogen.) Percine from the yellow perch (Perm flavescens) contains 85.5% of diamino-acid nitrogen and 9.8% of monoamino-acid nitrogen the former being mainly arginine (78.1%) with some histidine (5.6%). No lysine was present.The protamine from the pike perch (Stizostedion uitreum) proved t o be identical with this. That from the tunny (Thynnus thynnzbs) (compare Ulpiani A 1903 i 215) which is termed thymine contains 80% of arginine nitrogen no lysine or histidine and 10% of monoamino-acid nitro- gen. The sulphate like that of other protamines separates from a.queous solution as an oil. Thynnine also contains tyrosine. Pclccmys sarda contains a very similar protamine. The protarnine of the sword fish contained 81.5% of arginine nitrogen and 14% of monoamino-acid nitrogen. Neither histidine nor lysine were I resent. The protamine of Oncorhynchus tschawytscha the Chinook salmon (compare A. E. Taylor A. 1909 i 344) is identical with the salmine from Rhine salmon (Kossel and Dakin A.1904 i 355 702). I n the white fish (Coregoaus aZbzcs) the proportions of arginine and monoamino-acid nitrogen are 87.3 and 9.4. I n the lake trout (Salvelimus) they are 88.9 and 7.1 whilst in Esocine the protamine of the pike (Esoz Zucius) they are 86.3 and 11.3. I n general these protamines contain two molecules of arginine t o one molecule of monoamino-acid-in a few protamines the pro- portion of monoam;no-acids is larger. The protamines are thus to be-expressed by the formula u2m where a is arginine or (aZh),m when all three diamino-acids are present the proportion of diamino- acid being again as 2 t o 1. A table is given of the known protamines and their formulE. The Lipoids of Nervous Tiwue. CESARE SERONA and ANOTOINETTE Pa~ozzr (Cheni. Zentr.1913 ii 1064-1065 ; from Arch.

To separate the constituents the following process was employed. The brain was extracted with 5-6 times its weight of a mixture of equal parts of alcohol and ether. From the residue a substance could be extracted with hot alcohol with m. p. 164-165O which had the properties of homocerebrin o r cerasin.

The acetone extract was fat-free and contained besides some phosphatic lipoids and cerebrin which became insoluble on solution and reprecipitation with acetone chiefly cholesterol and its fatty esters. The ethereal extract could be separated into two fractions one insoluble in cold alcohol yielding a substance corresponding with Thudichum’s and Koch’s kephalin which appears on further investigation to be an impure lecithin mixed with cerebrin and a soluble fraction consisting also chiefly of impure lecithin mixed with cerebrin. The alcoholic extract was also separated into fractions soluble and insoluble in cold alcohol The former consisted of cerebrin m.p. 190-192’ which on hydrolysis yielded zt fatty acid ni. p. 74-75O presumably cerebrotinic acid and a reducing sugar with [u]? +27*5O and a substance which is possibly galactosamine. The part soluble in cold alcohol m. p. 160-165O is apparently impure homocerebrin or cerasin. S. B. S. Influence of Activity on Automatic Rhythm In Heart Muscle. GEORGE R. MINES (Proc. plr ysiol. SOC. 19 13 xiii ; J. Physiol. 47).-If a frog’s or mammal’s heart is made to beat faster the subsequent automatic rhythm is slowed; in the octopus the reverse occurs. I n both cases forced activity leads t o formation of acid but in different hearts and different parts of the same heart the optimum hydrogen ion concentration is different.I n some cases the increase will be towards this value in others away from it.

Chein. 191 3 88 2 10-245).--‘rhe perfusion fluid employed was Ringer’s solution containing in it dog’s blood- corpuscles washed by centrifugalising.I f the liver (dog) is freed from glycogen by phloridzin poisoning the perfusion leads to a slight but constant formation of sugar. If then diliydroxyacetone is added the amount of sugar formed (dextrose) is increased. The addition of dl-glyceraldehyde t o the perf using fluid increases the sugar formation greatly; this sugar is in part d-sorbose. The aldehyde appears t o be directly transformed into the sugar with previous rupture into short carbon chains. Glycerol forms dextrose less than the two trioses.

The preseace of n-valeric acid or of propionic acid prevents its formation from acetic acid. Formic acid is witli- out influence and is but little attacked on passing it through the liver. dl-Lactic acid has less effect on the reaction than propionic acid. The conversion of acetic acid into acetoacetic acid is greatly retarded when the liver is full of glycogen. The addition of glycollic acid to the blood stream increases the formation of aceto- acetic acid in the liver altliougli t o a less extent than acetic acid. E. F. A.

Extracts of brain produce the same effect but less markedly; no other animal extracts act in the same way.Probably as a result of cerebral activity some waste product acts as a hormone to stimulate the activity of the choroid cells and from the richness of the cerebro-spinal fluid in carbon dioxide it is suggested t h a t one function of the fluid may be to enable the brain t o get rid of this material. Reasons are given why this hormone is considered to act on the gland cells and not on secretory nerves. The hormone in question is not found in the cerebro-spinal fluid itself except in cases where catabolism is in excess as in degenerative processes of the central nervous system. Other agents which produce an increase of the fluid are excess of carbon dioxide in the blood and drugs which interfere with respiration. The volatile anaesthetics have a similar action ; these may act by interfering with oxygenation o r by altering the physical condition of the secreting cells.A large number of substances were investigated but all the reiiiainder gave negative results if respiratory and vascular effects were excluded.

The addition of calcium chloride to milk before coagulation by rennet increases the nitrogen and phosphate content of the coagulum and accelerates the action due t o its converting the sodium salts into insoluble calcium salts and thereby destroying the solvent action of the former on the casein.T. A. H. Paychic Hyperglgcemia in Rabbits. IVAN BANG (Zeitscl~ phtpiol. Ch+m 191 3 88 44-46).-Hir>ch and Reinbach (ibid. 19 13 87 122) have described a hyperglycaemia and glycosuria in rabbits as the result of fright. The non-recognition of this condition produced by psychical causes renders much work on the general subject untrustworthy. The existence of such a psychic condition in rabbits and other animals is confirmed in the present paper. W. D. H. Pentosuria from the Chemical Point of View ERNYT ZERNER and RUDOLFINE WALTUCH (d-lonatsh. 1913 34 1639-1653).-1n most cases of pentosuria which have been investigated optically inactive urines have been encountered from which osazona apparently corresponding with i-arabinose or I-arabinose have occasionally been isolated. Two new cases of pentosuria have now been examined.The urines were inactive which is taken as an indication of the absence of I-arabinose since this has a very high specific rotation. The osazone obtained had m. p. 162-163O and a small d-rotation which was insufficient to distinguish it from d-arabinosazone. Diphenylmethanedimethyldillydrazine (Braun 1910 i 525) gave no indication of arabinose. A mixture with an equal weight of I-xylosazone had m. p. 208-210° whereas i-xylosazone has m. p. 210-215O (Fischer A. 1894 i 566). The osazone from these urines is therefore d-xylosazone and very probably the pentose is d-xylose. Further experiments are being carried out definitely to determine the nature of the sugar.J. C. W. The Sugar in Pentoauric Urine. CARL NEUBERG (Biochsm. Zeitach. 1913 56 506-507).-Zerner and Waltuch (preceding abstract) have maintained that the sugar isolated by them in a WIT C ~ V . i. 5 ci. 141 6 ABSTRACTS OF CHEMICAL PAPERS. case of pentosuria was d-xylose as the mixture of its osazone with that of the corresponding I-derivative has a higher melting point than the pure substance. A mixture of the I-form of osazone with the osazone obtained from the urine of the cases of pentosuria of the author did not produce a corresponding rise in the melting point. The author does not see therefore any reason to suppose that the sugar in his case is other than the dl-arabinose as originally suggested. It is conceivable that various forms of pentosuria exist.S. B. S. Physiological Action of Colloidal Carbon. GUIDO 1z.m and C. PATANE (Biochem. Zeitsch. 191 3 56 307-318).-The so-called mellogen produced by the disintegration of a carbon anode by a galvanic current was used in these experiments. It can be dis- persed in water made slightly alkaline by sodium hydroxide which mixture is afterwards neutralised by passing in carbon dioxide and heating. This preparation has no influence on the total autolysis of the liver. It increases the amount of uric acid formed by autolysing ox-spleen and liver and inhibits the uricolytic action of ox-kidneys and washed pulp of dog’s liver. Intravenous injections of large quantities into rabbits white rak pigeons etc. produce dyspncea but only a few of the animals succumb.The intravenous injection has no appreciable effect on body temperature (rabbits) but increases the amount of carbon dioxide in expired air (as compared with control injection of distilled water). The amount of increase is approximately proportional t o the amount of mellogen injected. 5. B. S. Action of Colloidal Sulphur on Autolysis. ANTONIO FAGIUOLI (Biochom.

Cl~sm. 191 3 16 169-1S6).- The subcutaneous administration of creatine t o rabbits causes a small increase in the creatine content of muscle (about 5% in five experiments). This is quite insufficient to account for the creatine which does n o t reappear in the urine. The administration of creatinine exerts a similar effect ths creatine content of the muscles being 6% above the normal an amount sufficient t o account for the creatinine which was c o t eliminated by the kidneys.This apparent increase in the muscular creatine was not due t o a retention of unchanged creatinine. Of the creatine given 25-80% (the quantity depending on the amount injected) reappeared in the urine unchanged whilst Z-lO% was eliminated as creatinine. When creatinine was administered 77-82% (average 80%) re- appeared in the urine and no elimination of creatine was detected. W. D. H. Narcosis and Oxygen Consumption. JACQUES LOEB and HARDOLPE WASTENEYS (Biochem. Zeitsch. 19 13 56 295-306).- The authors discass the relationship between inhibition of oxidation and narcosis. When the embryos of Fzcndulus are not narcotised they respond by rapid movement to a stimulus of N/25-hydrochloric acid.It was found that they only become insensitive t o this stimulus when their oxidation rate has been reduced t o 1/14 of the normal value by potassium cyanide; a reduction by this method to 1 / 9 is without influence on their response to the stimulus. On the other hand they become unresponsive to chloro- form treatment without any appreciable reduction of the oxida- tion rate. Ethyl ether and butyl alcohol can produce insensitive- ness t o the strongest stimuli with the diminution of the oxidation rate by only 26%. Medusa loose their mobility and reactivity to stiniuli by direct reduction of oxidation by potassium cyanide only 5 c 2i. 1418 ABSTRACTS OF CEEMltCAL PAPERS. wheu this reduction is 3-6 times as great as that which result& when the motility and reactivity are destroyed by ethylurethane? The conclusion is drawn that narcosis cannot be due directly t o reduction of oxidative capacity and that the latter is a result either of inactivity of the tissues due to narcosis or it is a secondary action of the narccltis which stands in no direct relationship to the narcosis Itself.Biological Oxidation of Certain Glucosides. .J UHO HAMALAINEN (Chem. Zrlztr. 1913 ii 13 19 ; from #knnd. Arch. I-'lLysio?. 1913 30 187-190).-ATter injection of the glucosides of certain terpene alcohols the Corresponding glycuronates appear in the urine. There is therefore no preliminary scission of the glucoside into sugar and alcohol for neither in the blood nor in the organs could any terpene be detected.On the contrary both glycuronate and the corresponding glucoside could be found. The facts confirm the theories of Fischer and Piloty and of Sundvik on the formation of conjugated glycuronates in the organism. Furthermore more glycuronate is excreted after administration of the glucoside than after administration of the fr>e substance. The Influence of Certain Quinoline and Naphthaquinoline Derivatives bn the Excretion of Uric Acid KICCARDO LUZZATO and RICCARDO CIUSA (Chem Zenir. 1913 ii 1318-131'3 ; from Arch Rarrn. spei*i~n. 191 3 16 6-40).-'l'he followrtg derivatives were investigated 2 - p - methoxyphenylquinoline- 4 - carboxylic acid 2 - p - dimethylaminophenylquinoline - 4 - carb- oxylic acid 6-amino-2-phenylquinoline-4-carboxylic acid 3-phenyl- fl-naphthaquinoline-l-carboxylic acid 2-p-dimethylamino-fl-naphtha- cinchonic acid 2-phenyldihydro-fl-naphthaquinoline-4-carboxylic acid 2-o-hydroxylphenyl-fl-naphthacinchonic acid 3-phenyl-fl-naph- thaquinoline and 2-phenylcinchonic acid (atophan).Of these i t was found that 3-phenyl-j3-naphthaquinoline-l-carboxylic acid (the so-called diapurin) and atophan caused an intense excretion of uric acid the action of the latter being scmewhat less than that of the former. It caused however no turbidity of the urine and wa.9 better tolerated and a dose of 5 grams caused no bad symptoms in a dog of 12 kilos. weight ar_d could be taken by a man in doses of 2 grams for several days without ill effects. The action of diapurin is attributed to .the mobilising effects on the uric acid which already exist in the organism as a result of purine degradation as the increased excretion of the acid is not accom- panied by an increased phosphoric output which should result if the nucleins are broken down.Furthermore the increased output of uric acid ceases two or three days after administration of the drug. The particular action on the uric acid is due t o the presence of a phenyl group in the 2-posi tion the quinolinecarboxylic acid group being inactive. The action is neutralised by the presence of the metlioxyl and amino-groups in the 6-position. On the other band 2-phenyl-6-rnethylquinoline-4-carboxylic acid (paratophan) and 8-methoxy-2-phenylquinoline-4-carboxylic acid (isatopban) are fairly active. The introduction of the OH S.B. S. S. B. S.PBYSlOLOQICAL CHEMISTRY. i 1419 Nhle or OlSle group into the 2-phenyl ring inhibits or weakens the action on uric acid. As hy$rcxyph.c?nylquinoline-4-carboxylic acid is according to Sk'orczewski and S o h a degradation product of atophan the latter appears t o exert its influence before oxidation. The reduction of the pyridine ring destroys or weakens the action.

Mechanism of tho Biological Action of t h e Rontgen Rays. EUGEN PETRY (Niochem.

Amoebae obtained from hay-infusion were used as the objects of experiments and these were submitted t o the action of uranium nitrate sodium tungstate zinc sulphate and colloidal zinc sulphide in the dark in the presence and the absence of Rontgen radiation. -4s a result it was found that the rays had no appreciable effect in increasing the toxicity of the metals. Compounds were purposely chosen which fluoresce when submitted to radiation.The rays exerted no action on the sensitising activity. Experiments were also carried out t o ascertain whether organs which are highly sensitive t o Rontgen rays contain substances which act as light-catalysts for these rays. Testicles and lymph glands were chosen and the effect of radiated and unradiated extracts on hEmolysis the mobility of arnebze and the milk-clotting by rennin were investigated. The results were negative and the author draws the conclusiou that no substances have been dis- covered which act as catalysts for the Rontgen rays in the same way that eosin acts as catalyst for actinic rays.

Itnmun. expt. Z’harapie 2913 18 i 410-422).-Just as according t o the author the proteins use the amino-acids as inhermediary products in developing their thromboplastic action the nucleoproteins act by intermediation of the purine bases. Thus nucleoproteins otherwise harmless can be rendered toxic by degradation of their iiiolecule or by the addition to them of degradation products or even amino-acids. Under these conditions curves were obtained similar to those described by the author for proteiii s showing iii ail oscillatory manner thrombo- plastic arid aiititliroinbic phases. The first of these is short and may be overlooked. The iiucleins produce a strong antithrombic secretion. The antitliroriibic phase is of short duration but pro- duces a distinct although short-lasting immunity.The nucleo- proteins can be activated either by purines (affecting the nucleic acid part of their iiiolecule) or by amino-acids (affecting the protein part). Nucleohistones owiiig t o the presence of the liistone group are directly toxic. For many iiucleoproteins such as those from the thymus animals are directly anaphylactic in the same way that carnivora are sensitive to peptones. S. B. S.

Comparing beer and wort i t is shown that whilst the electrical conductivity remains the same the osmotic pressure becomes three times as great during fermentation. E. F. A. Extraction of 2yn:ase by means of Liquid Air. HENRY H. DIXON and WJLLIAM R. (f. ATKINs (Sci. Proc. Moy. Dubl. Soc. 1913 14 1-8).-Immersion of yeast in liquid air from ten to fifteen minutes renders the protoplasm permeable. On thawing the yeast liquefies and after centrifuging the sap of the cells is obtained as a faintly opalescent brown liquid. This contains zymase in as active a form as that prepared by Lebedev's maceration method.The amount of zymase extracted may be increased by dilution and maceration. The sap is practically free from glycogen and does not show autofermentation. The sediment froths actively due to hydrolysis of the glycogen in the cells and fermentation of the sugar formed. E. F.

If this ratio falls below 2 however then the maximum growth is never obtained. This explains the differ- ence between the author's results and those of Javillier (compare A 1908 ii 317) who grew the mould on liquid where the ratio v / s was 1.5. W. G. Polyatomic Alcohols as Sources of Carbon for Lower Fungi. RAY E. NETDTG ( J . Biol.

With increasing carbon the availability does not increase ; adonitol for example does not compare favourably with glycerol or even erythritol and two of the hexatomic alcohols failed t o yield cultures equal to those on glycerol. No connexion between availability and carbon asymmetry could be established. There may however be some relation between availability and the na.ture of the inter- mediate oxidation products since all the substancee which are available including gIycero1 yield oxidation products containing one or more asymmetric carbon atoms.

Compare Maze and Perrier A. 1904 ii 676; Herzog and Polotzky A. 1909 i 285; Wehmer this vol. i 229).-Unsuccessful attempts are recorded to produce citric acid from alcohol or from lactose by means of fungi. The author thus confirms Herzog and Polotzky's conclusion with regard t o the non-formation of citric acid from alcohol (contrast Maz6 and Perrier) but differs from them in finding that it is also not produced from lactose. Two species of Citromyces were grown during several months in a nutrient solution containing ammonium nitrate potassium phosphate magnesium snlphate calcium carbonate and alcohol (2.5 and 5%). The latter exerts a marked retarding effect on the growth of the fungi which differs in extent for the two species.Citric acid could not be detected. Under similar conditions a like result was obtained with lactose solutions in which however growth of the fungi occurred readily. JOSEF G&SL (Zeitsch. physiol.

Compare A 1911 ii 523; 1912. ii 286; this vol. i 324).-Some new experiments in support of the view that nitroxyl NOH plays an important part in the assimi- lation of nitrogen have been carried out partly on the heights of Monte Rosa where the activity of the light was nearly equal to that of a mercury lamp.It was found that the liberation of oxygen from solutions of potassium nitrite or nitrate was greatly accelerated by carbon dioxide. Nitric oxide in presence of form- aldehyde or methyl alcohol soon produced formhydroxamic acid. Nitric oxide and water with yellox phosphorus as catalyst gave ammonium nitrate in sunlight and ammonium nitrite in mercury light. Nitric oxide itself was detected in moist air which had been passed through dilute alkali and then exposed t o brilliant sunlight. Substances of the na'cure of a-amino-tcids were obtained by the action of mercury light on potassium nitrite in presence of carbon dioxide with ferric chloride as catalyst.A new course for the photo-synthesis of organic substances from air carbon dioxide and water is thus indicated. Ammonia was oxidised to nitrous acid in presence of oxygen under the influence of mercury light. A diagram is given which summarises the numerous photo- reactions between simple carbon nitrogen and oxygen compounds which Baudisch Piloty and Stoklasa have :tlready discovered. H. W.

Lccndw. 1912),- Certain plants such as barley when supplied with ammonium chloride produce amides a t the expense of proteins whilst the ammonia is also converted into asparagine or glutamine. No accumulation of ammonium salt takes place. I n the case of peas and vetches ammonium salts do not increase the amount of asparagine and may even diminish it. When however calcium carbonate is supplied along with an ammonium salt the latter is converted into asparagine. With lupines the presence of ammon- ium salts both alone and with calcium carbonate diminishes the smount of asparagine whilst the plant accumulates ammonia chiefly from cleavage products of the proteins.Lower plants can accumulate ammonia without injurious effects. In lower animals proteins are degraded to ammonium salts which are not completely converted into amides. N. H. J. M. Effect of Cbloroform on the Respiratory Exchanges of Leaves. D. THODAY (Ann. Bot. 1913 27 697-717).-Different varieties of leaves when treated with small amounts of chloroform showed increased absorption of oxygen and a similarly increased production of carbon dioxide. I n starved leaves the stimulation was generally prolonged.When the amount of chloroform was sufficient to cause visible disorganisation the production of carbon dioxide was diminished whilst the absorption. of oxygen was no longer closely correlated with the production of carbon dioxide. Leaves of Tropeolum which contain no tannin showed a depression of oxygen absorption greater than that of the production of carbon dioxide. In 1ea.ves of cherry Portugal laurel and Helinnthus which contain tannins the absorption of oxygen was very rapid f o r a short time and although quickly falling remained a t a much higher level than the production of carbon dioxide.

Compare Keeble and Armstrong A 1912 ii 673; this vol. i 325 803).- The absence of a brown colour in the sap expressed froin plant tissues may be due (1) to the absence of organic peroxide ; (2) to the presence of tannin preventing the action of the oxydase; or (3) to the presence of some reducing agent or inhibitor. It is considered that oxydase is concerned in the production of cork and sclerenchyma. The distribution of oxydase and of a reducing agent in Iris species is described. The colours of Iris are due t o the presence or absence of a yellow plastid pigment and an anthocyan pigment.

VersucAs. -Stat. 19 13 79-80 176- 18 1. Compare succeeding abstract).-The name “ robin ” was applied by Kobert t o a protein first prepared from the bark of Eobinia peudacaciu by Power in 1889 (Pharm.Rzmdschau 1890 8 29) and subsequently charac- terised more completely by the same author (A. 1901 ii 679) who showed especially (1) that it was toxic but lost its poisonous pro- perties when heated ; (2) that it hydrolysed amygdalin and sinigrin ; and (3) coagulated milk like rennet ferment. These observations especially as regards the physiological action of the substance were confirmed and extended by Lau (Diss. Rostock 1906 (?1901)) Ehrlich (Kliiz. Jahrb. 1898 6 315) and others including the present author. I n the present paper it is shown (1) that “robin” undoubtedly behaves as a agglutinant with blood of various kinds; (2) is not toxic when injected subcutaneously into rabbits in quantities of 1 t o 10 C.C.of a 4% solution; (3) does not hydrolyse sinigrin; (4) does not coagulate milk; and (5) does not precipitate ricin-serum. The toxicity of the “ robin ” preparations examined by Lau is ascribed to impurity or to the use of abnormally large doses of the material. The toxicity of the bark it is sug- gested may be due to the alkaloid o r the glucoside it contains. From Robinia seeds a similar “ phasin,” which agglutinates blood but is not toxic and has no glucosidolytic activity has been pre- pared. T. A. H.

Compare A. 1911 ii 922).-Tlze results of pot experiments showed that lithium salts are toxic when the soil contains 0.003% or more of lithium whilst amounts not exceeding 0.002% have a stimulating effect. The best results are obtained with the nitrate (which is the most stimulating as well as the most toxic of the different salts) when the amount of lithium does not exceed 0.001%. Zinc salts have a slightly stimulating action on wheat when the soil contains less t1ia.n 0.02% of zinc. Larger amounts of zinc have a toxic action. Lead salts have no toxic effect when the soil contains as much as 0.03% of lead. It is worthy of note that much larger amounts of zinc than of lithium may be present in the soil without having any injurious action on wheat the relative amounts being 10 1.As regards the period in which the stimulating action takes place the results so far obtained'seem to indicate that it is during the germination of the seed rather than later. The action may result in considerable alterations in the development of the plant in root production and even in the character of the grain. The nitrate seems to have a stimulating effect. N. H. J.

The results of this investigation show that the optimum temperature for the production of the maximum amount of reducing sugars is near 65* and that the best proportions of flour and water lie between 1 4 and 1 10 little difference being observable between these limits.The trans- formation is mainly effected in the first hour (approx. 88% of the total change) and under favourable conditions more than two- fifths of bhe flour undergoes conversion into soluble substances (calculated as maltose). Small quantities of sulphuric acid sodium hydroxide dipotassium hydrogen phosphate and sodium chloride all exert an inhibitory effect on the action of the enzymes of the flour the influence being most marked with sodium hydroxide and least with sodium chloride. Although little difference is observable between the quantities of reducing sugars formed in the action of water on various grades of flour from the same wheat the inhibitory effect of the chemicals named is less marked with a low grade than with a straight flour.The Amounts of Sulphur and Chlorine in the Rice Plant.

The different plants of which peats are formed are studied and the results of numerous analyses tabulated wit Ti a discussion 011 the possible significance of tlie facts observed. Manurial Experiments with Calcium Cyanamide Sodium Nitrate and Ammonium Sulphate on Sand and Peat Soils. BRUNO TAC‘KE and FR. HRUNE (Laizdzo. lrewmc?~s.-Stut 1913 83 1-100).-Frank’s calciuni cyanamide and Polzeniuss’s calcium cyanamide (which contains calcium chloride) give similar results on sandy soils. On 1)eat.y soil the latter only had 81% of the value of Frank’s manure. Calcium cyanamide sliould be applied riot with the seed but at least a week beforehand; and i t should a t once be harrowed in. Different crops show different degrees of sensitiveness rye being more sensitive than oats and potatoes when the manure is applied as top dressing whilst oats is specially liable t o injury when the inaiiure is applied a t tlie saiiie tirlle as the seed.
