Of the following papers, those marked * were read: "98.The action of tartaric acid on tin in the presence of oxygen."6L By Alfred Chaston Chapman. When tin is partly immersed in a 5 per cent. aqueous solution of tartaric acid, no action occurs unless air is present. In these circumstances oxidation takes place at the surface of the liquid, and stannous tartrate is formed. If the action is allowed to proceed at the ordinary temperature, well-formed crystals slowly separate, the solutions in the case of the author's experiments having been allowed to remain undisturbed for three years. Contrary to existing statements, stannous tartrate readily undergoes dissociation even in the presence of tartaric acid, yielding under some con- ditions a colloidal solution. In the presence of a restricted supply of oxygen the stannous oxide undergoes slow oxidation, forming a brown-coloured, colloidal solution, which may contain as much as 6 per cent.of tin, and which, when heated with free exposure to the air, becomes converted into a bluish-white, colloidal liquid containing hydrated stannic oxide. The brown- 123 coloured solution evidently contains an oxide of tin intermediate between stannous and stannic oxides-probably tlie sesquioxide, the existence of which, on theoretical grounds, is very probable, and which has been referred to by several observers. That the oxide in question is not a molecular compound of stannous and stannic oxides is rendered probable by the fact that the brown colour is developed in solutions containing as much as 20 per cent.of sulphuric acid. Attempts to isolate the intermediate oxide and to prepare a tin alum have not been successful up to the present. DISCUSSION. Mr. F. P. WORLEYasked if the author had thought of employing other oxidising agents, such as hydrogen peroxide, in place of atmospheric oxygen. The latter obviously acted as depolariser, uniting with the hydrogen of the acid to form water, thus supplying sufficient energy to make the interaction exothermic. Mr. CHAPMANsaid that the conditions under which the coloured oxide was formed, and tlie fact that similarly coloured solutions could be obtained in the presence of 20 per cent. sulphuric acid, rendered it, in his opinion, exceedingly probable that the oxide was a definite oxide-probably the sesquioxide-and not a combination of two oxides.The precise causes leading to the formation of the colloidal condition were often very difficult to determine, and he had not been able to ascertain why the stannous hydroxide assumed a colloidal state in some cases and not in others. The crystals formed in these experiments consisted of pure stannous tartrate, and there was no evidence that the OH-groups had been attacked. The effect of hydrogen peroxide and permanganate had not been tried. Only two experimental bottles had been kept in the dark, and in neither case had there been any action on the tin, but this might quite well have been due to the fact that in these bottles the corks were air-tight. "99. ''The reaction between ferric salts and thiocyanates." By James Charles Philip and Arthur Bramley.It has been observed by various workers that the colour of the red solution obtained by mixing a ferric salt and a thiocyanate gradually diminishes in intensity. This is associated with the progressive reduction of the ferric iron to the ferrous condition, and the present investigation deals with (1) the products of the reaction, (2) the velocity of the reduction, as this is affected by altering the concentration, temperature, and other factors. Corresponding with the reduction of the iron, there is an oxida 124 tion of thiocyanic acid, the sulphur appearing as sulphuric acid, and the carbon as carbon dioxide, whilst the nitrogen of the oxidised acid is converted, partly at.least, into ammonia. The velocity of reduction of t,he ferric iron is quite appreciable at the ordinary temperature, and increases rapidly as the tempera- ture rises. At a given temperature the change is very much slower when ferric salt is in excess than when thiocyanate is in excess. In the latter case addition of acid retards the reaction to a notable extent. *loo. ‘(The preparation of pure bromine.” By Alexander Scott. The author recommends as the source of the purest bromine commercial potassium bromide, which has been boiled with small quantities of bromine water in order to eliminate any trace of iodine which may be present. The bromide, after recovery from the solution, should be fused with potassium dichromato in quantity somewhat less than that required for the liberation of all the bromine on treatment with sulphuric acid.The bromine thus obtained is free from chlorine, iodine, and all organic compounds. The bromine of commerce may be completely freed from the other halogens by shaking it with small quantities of pure sodium hydroxide solution, when the chlorine is removed as chloride and the iodine as iodate. It is easy to detect 1 part of iodine in 100,000 of bromine in this way by means of nitrosulphonic acid and chloroform, using only 10 cubic centimetres of bromine. A simple form of apparatus, entirely of glass, was shown for the distillation of large quantities of bromine and similar substances without any inconvenience.“101. ‘(The preparation of conductivity water.” By Robert Bourdillon. Most of the methods hitherto described for preparing conduc- tivity water produce water of a conductivity of 0.7 gemmho or more. A still has been made which gives seven or eight litres of water of a conductivity below 0.2 gemmho by a single distillation from tap water. The essential features are a large copper boiler, a spray trap consisting of a spiral coil oC copper tubing, a condenser made of a vertical tin tube up which a current of purified air is passed, and the addition of a little potassium hydrogen sulphate to the water in the boiler. It is also found that by the use of an air-tight electrolytic cell, water of a conductivity of less than 0.2 gemmho 125 can be kept with only a very slow rise of conductlivity, so that very dilute solutions can be studied accurately.DIscusSION. Mr. BOURDILLONsaid, in reply to Prof. Baker, that the copper coil and trap described were loosely jacketed with cotton waste and boiler felt, but, in spite of this protection, about one-sixth of tho steam from the boiler was condensed there. *102. Gg The constitution of the anhydro-bases derived from tetra-hydroberberine alkyl hydroxides.” By Frank Lee Pyman. The formation of anhydrebases by the dehydration of tetrahydro-berberine and I-canadine (Z-tetrahydroberberine) methohydroxides has been investigated. It was shown that in the former case two, and in the latter three, isomeric anhydro-bases are formed.As a result of the experimental data and theoretical considerafiions, it was concluded that the formation of the anhydro-bases may be explained by the following scheme : CH Base A. 71 h\ Canadine metho-dl-Tetrahydrobesberitic hydroxide. methohydroxide. I I CK2 I1 \/\C&/\/ I INMe gH/\/ CH2CHL? Base C (optically active). Base S (optically inactive). The views of Voss and Gadamer (Arch. Pharm., 1910, 248, 43) and of McDavid, Perkin, and Robinson (T., 1912, 101,1208) with regard to the constitution of the anhydro-bases derived from tetr;cr hydroberberine alkyl hydroxides were discussed, 126 103. ‘(The application of Hofmann’s reaction to dialkylacetamides.” By Frank Lee Pyman. It was shown that the dialkylacctamides-in particular dipropyl- acetamide-do not behave precisely similarly to the normal aliphatic acid amides (compare Hofmann, Ber., 1882, 15, 407, 752, 762; 1884, 17, 1406, 1920) in respect of their behaviour to bromine and a1 kali .Thus diethyl-and dipropyl-aceto bromoamides are readily obtained in a crystalline form, whilst the bromoamides of the acids of the normal aliphatic series higher than propionic acid cannot be so isolated. Dipropylacetobromoamide when treated with an excess of aqueous sodium hydroxide gives 8-aminoheptane in a yield amounting to 84 per cent. of the theoretical, whilst its isomericle, 7)-octoamide, under similar conditions yields only 30 per cent. of the theoretical quantity of n-heptylamine. Normal aliphatic acid amides (2 mols.) when treated with bromine (1 mol.) and aqueous alkali hydroxide8 give acylalkylcarbamides in excellent yisld : 2R=CO*NH,+Br, + 2KOH = R*CO*NH*@O*NH*R+2KBr +2H,O, but the dialkylacetamides, higher than isobutyramide, yield little or no acylalkylcarbamide, the corresponding dialkylcarbamide, for instance, s-di-5-heptylcnrbamide in the case of dipropylacetamide, being obtained.The behaviour of dialkylacetamides thus resembles more closely that of phenylcarbimide than that of the normal aliphatic acid amides. 104. (L Derivatives of o-xylene.” By John Lionel Simonsen. A full account was given of work which has already been briefly mentioned (P., 1913, 29, 26). The following substances were described : 3-nitro-o-xylene-5-szrlphonicacid, 3-o-xylicFine-5-stclphonic acid, 3-?zitro-~x?/lene-4-sulpT~onicacid, 3-o-xylidine-4-sulphonicacid, 4-nitro -o -xylene-5-sulpl~onic acid, 4-o-xylidine-5-sulphonicacid, 3-o-xylidine-6-sulpT~onicacid, and 4-o-xylidine-6-sulphonic acid.105. ‘(Synthetical production of derivatives of dinaphthanthracene.” By William Hobson Mills and Mildred Mills. In connexion with their recent communication on this subject (T., 1912, 101, 2194) the authors overlooked a paper by Dr. Ernst 127 Philippi, ‘‘Ueber eine Synthese von linearen Diphthaloylbenzol ” (Monatsh., 1911, 32,631), in which is described the preparation of dibenzoylisophthalic acid, dibenzoylterephthalic acid, and di-naphthanthradiquinone by the same methods as were employed by them.The authors greatly regret their oversight. 106. 6d The alcohols of the hydroaromatic and terpene series.” (Preliminary note.) By Robert Howson Pickard, William Lewcock, and Joseph Pates. The methods adopted for the isolation and purification of the borneols and isoborneols (T., 1907, 91,1973) and of the menthols (ibid.,1912, 101, 109) have been applied to fenchyl alcohol and isopulegol. The reduction of d-fenchone by means of sodium in moist ethereal solution yields Z-fenchyl alcohol, very little (if any) of the other possible isomeride being formed. This alcohol, by purification of the hydrogen phthalate, has now been obtained with a higher rotatory power than that stated in the literature. The successive fractionations of the magnesium and cinchonine (m.p. 174O) salts of this ester yield a hydrogen phthalate (m. p. 147O with [a],,+22’4O in chloroform), which, when hydrolysed, gives l-fenchyl alcohol with [u]”D”-15’5O. Tiemann (Ber., 1896,29, 914) prepared isopulegol with [a], -2.9O from the condensation products of citronellaldehyde. His work has been repeated, and from these products.one of the theoretically possible isopulegols has been isolated in a pure state. This has a specific rotatory power [a]y-22‘2O, and forms a hydrogen phthalate, which melts at 106O, has [a], -18’7O in chloroform, and forms a magnesium salt, melting at 115c with [a], +14.l0 in ethyl alcohol, and a strychnine salt, melting at 205O with [a], -17.1 in chloro- form.The application of these methods to the isolation in a pure state of the tertiary alcohols has been hindered by the difficulty of preparing their acid esters. The interaction at (say) llOo or above of equivalent amounh of such alcohols and acid anhydrides (phthalic, succinic, or camphoric) leads to the dehydration of the alcohols. It has, however, now been found that the long-continued action at temperatures below looo of the anhydrides on an excess of the alcohols gives good yields of the desired acid esters. In this manner optically inactive terpineol has been converted into its esters. The hydrogen pphthalate melts at 117O and the hplroyen smcinate at 45O, whilst both esters form crystalline salts with the commoner alkaloids.128 107. ‘‘Anew variety of manna and a note on the melting point of dulcitol.” By John Ralph Furlong and Lawrence Eversley Campbell. A specimen of leaves and twigs partly covered with a white incrustation (“ manna ”) was received recently at the Imperial Institute from Mr. C. N. B. Venables, North Western Rhodesia. The plant was identified at the Royal Botanic Gardens, Kew, as a Gymnosporia, sp., probably G. deflexa, Sprague. The incrustation had a slightly sweet taste, and was for the most part evenly deposited. It could be easily separated from the leaves and twigs, and contained 4.9 per cent. of moisture. On dissolving the manna in a small quantity of hot water and adding alcohol to the filtered solution, a crystalline substance separated in highly lustrous prisms melting at 183O (uncorr.) and 188O (corr.).This substance was optically inactive, even in the presence of borax, and did not reduce Fehling’s solution either before or after heating with dilute acid. On oxidation with nitric acid it yielded mucic acid, and on acetylation gave a hexa-acetyl derivative melting at 171O (corr.). These results prove that the crystalline substance is dulcitol; it was isolated to the extent of 54 per cent. of the weight of manna used. The residue of the manna after the removal of the dulcitol was a pale brown, sweet, gummy material, which reduced Fehling’s solu- tion, and gave indications of the presence of a furfuraldehyde-yielding complex. It contained 6.4 per cent. of reducing sugar, calculated as dextrose, and after heating with dilute acids yielded reducing sugar equivalent to 6.6 per cent.of sucrose, these two figures being expressed on the original manna. The residue could not be further examined owing to the small quantity available. Some confusion appears to exist in the literature as to the melting point of dulcitol ; for example, Beilstein, Abderhalden, Richter, and Watts in their handbooks give 188-189°, without stating that this is a corrected figure. Lippmann (Ber., 1892, 25, 3217) identi-fied as dulcitol a substance which melted at 188O (uncorr.). A sample of dulcitol (Kahlbaum) after repeated recrystallisation from alcohol, melted at 183O (uncorr.) and 188O (corr.). 108. “Blue adsorption compounds of iodine.Part 11. The influence of constitution on the adsorption by 2-and 4-pyrone derivatives.” By George Barger and Walter William Starling. In a previous paper (Barger and Field, T., 1912, 101, 1394) the colloidal properties of the blue substances were described which are 129 formed by iodine with starch, cholalic acid, and saponarin. The phenomenon has since been found to be quite general, and occurs with some fifty of the substances which the authors have so far examined. In one case, that of naphthaflavone, the reaction is even more delicate than with starch, and a blue coloration is produced in solutions containing 1 part of iodine in 800,000 parts of water. The power of adsorbing iodine seems to depend on the presence of a crossed conjugated linking,-and on the residual affinity of oxygen (or sulphur).It is by no means confined to pyrone derivatives. It is greatly increased by benzene nuclei, as in the coumarins, chromones, xanthones, and flavones ;alkyl- and hydroxy- groups diminish it. Thus coumarin adsorbs slightly, hydrocoumarin and hydroxycoumarins not at all ; naphthacoumarin, phenyl-coumarins, and benzogloxycoumarins are coloured blue by very dilute iodine solutions. The authors have thus, for the first time, been able to examine the effect of the chemical constitution of the adsorbent, and their results agree closely with those already obtained by Freundlich and others in the study of the converse phenomenon, that is, the capacity of various organic substances oE being adsorbed by the same adsorbent (charcoal). The general conclusions of the first paper have been confirmed and extended. In no single case is the iodine taken up in stoicheiometrical proportions, although many of the blue substances can be obtained crystalline.109. ‘‘Reactions of halogen-substituted acids. Part I. The action of sodium hydroxide and methoxide in methyl-alcoholic solution on bromoacetic, a-bromopropionic, and monobromosuccinic acids.” By Erik Host Madsen. The effect of methyl-alcoholic solutions of sodium hydroxide and sodium methoxide on various bromine-substituted acids has been examined. Both reagents give rise to the methoxy-derivative in the case of bromoacetic and a-bromopropionic acids, whereas mono- bromosuccinic acid gives the corresponding methoxy-acid with sodium methoxide, but malic acid with sodium hydroxide, both reactions being accompanied by the formation of some fumaric acid.In the case of the two first acids the velocity of reaction is the same for both sodium hydroxide and methoxide, but with bromo- succinic acid sodium hydroxide reacts with the greater velocity. The order of reaction is different with the three acids; a-bromo-propionic acid gives a reaction of the first order, bromoacetic acid 130 one of the second order, and bromosuccinic acid one of a higher order, which was not determined. 110. (‘The preparation and analysis of methane.” By Colin Campbell and Albert Parker. Methane was prepared by the action of hot water on pure aluminium carbide.Acetylene was removed by means of an ammoniacal solution of cuprous chloride. The gas was freed from hydrogen by first adding a slight excess of oxygen and then passing the mixture over palladium black at 90° to looo. Analysis showed the methane to be practically pure. A method of analysis was devised, by which 0.05 per cent of hydrogen could be estimated. 111. ‘(Influence of increase of initial temperature on the explosiveness of gaseous mixtures.” By Albert Parker. Mixtures of methane, carbon monoxide, hydrogen, and coal gas were made with oxygen and with air, and sparked in a eudiometer tube at the ordinary temperature and at looo under various pressures. It was found that increase of initial temperature decreased the values of the lower limits of explosibility of the above gases.It was also found that the values of the lower limits of explosibility of methane, carbon monoxide, and coal-gas were higher for mixtures with oxygen than for mixtures with air. 112. ‘I Keto-enolic tautomerism and the absorption spectra of the aliphatic ketones.” By Harry Medforth Dawson. From an examination of the data expressing the rate at which the aliphatic ketones react with sodium hydrogen sulphite and hydroxylamine, it was shown that these reactions have no connexion with the intramolecular change of linking associated with the keto- enolic transformation. These data cannot therefore be cited in support of the view that selective absorption in the ultra-violet is connected with the intramolecular change of linking involved in the transfer of a labile hydrogen atom (compare Baly and Desch, T., 1904, 85,1029; 1905, 87, 766; Stewart and Baly, ibid., 1906, 89, 489).The interpretation of absorption spectra and of extinction curves was discussed, and it was shown that the so-called persistence of a selective absorption band is of no particular value, In order to obtain comparative numbers representing the selective absorption capacities of the individual members of a group of similar sub- 131 stances, measurements are required which will afford a means of ascertaining the relative thicknesses of layers of equimolar solutions which give rise to the same amount of selective absorption. The absorption-coefficients of the aliphatic ketones for light of the frequency supposed to be characteristic of the *CII,*CO*group were shown to have no connexioii with the corresponding rates of isomeric change.Furthermore, in the case of acetone it is found that when the rate of isomeric change is increased to something of the order of 100,000 times, there is practically no alteration in *the absorption of the characteristic ultra-violet radiation. These facts indicate that the behaviour of the simplest keto-enolic tautomerides is absolutely incompatible with the Baly-Desch theory. 113. (‘Experiments on the synthesis of apomorphine.” By Francis William Kay and Am6 Pictet. With the object of synthesising apomorphine, the authors have attempted the preparation of 2-nitroveratryldihydroisoquinoline .(II), by means of reactions already described by them (Ber., 1909, 42, 1973).On submitting such a derivative of isoquiiioline to a treatment similar to that described by Pscliorr (Ber., 1904, 42, 1926) and by Gadamer (Arch. Phccrm., 1911, 680, 249) for the conversion of iiit,ropapaveriiie into dl-glaucine, it would be expected to yield the diniethyl ether of apomorphine (111): CH, ,Me0\/ Although 2 -nitroi2omoueratroyl-P -phenylethylarni/ie (I) does actually lose water when heated with phosphoric oxide in solution in boiling toluene, yet it fails to yield a derivative of isoquinoline by ring-formation as would be expected, a yellow, indifferent sub- stance, m.p. 129O, being obtained instead. This dehydro-product is still a derivative of phenylethylamine, for when reduced with tin and hydrochloric acid it yields that base. o-Nitrophenylacetyl-P-phenylethylainine,colourless crystals, m. p. 97-99O, fails to lose water when submitted to the action of phosphoric oxide in boiling xylene. 114. (( The absorption spectra of various derivatives of benzene.” By John Edward Purvis and Nial Patrick McCleland. The absorption spectra of the vapours, solutions, and thin films of some of the simpler benzene derivatives have been compared, and particularly various nitro-compounds. The results were discussed from a consideration of the oscillations of different electronic centres.115. “Notes on the determination of the electrical conductivity of solutions.” By Harold Hartley and William Henry Barrett. The electrical resistance of aqueous solutions of potassium chloride has been measured by a telephone and induction coil, and also by the rotating commutator and galvanometer, and it has been found that the two methods yield different values for the resistance. The values found by the telephone are about half a per cent. lower than those found by the second method. A new form of conductivity cell has been devised for use with dilute solutions of aqueous and non-aqueous solutions in which the solvent is protected from contact with atmospheric impurities. 116. ‘‘Mechanism of the transformation of ammonium cyanate into carbamide, and of the decomposition of carbamide by heat.The polymerisation of cyanic acid.” By Emil Alphonse Werner. It was pointed out that the theory recently put forward by Cliattaway (T., 1912, 101, 170) to explain the transformation of ammonium cyanate into carbamide, and the formation of biuret and cyanuric acid from the latter is open to serious objection, since it fails to account for several of the phenomena connected with the changes, and is not in agreement with others. The reversible reactions given by Chattaway, namely : H,N*NCO ZZ H*N:C:O+NH, ZE HN:C<NH,,OH is difficult to conceive, cyanic acid being supposed to have the fixed constitution H*N:C:O*. The whole series of changes, it was shown, can be easily explained and understood by taking into consideration the two fundamental causes, namely, dissociation and the reversible change, HO*CN +-HNICO, and no hypothetical intermediate compounds are required to help 133 the explanation.Thus, the following scheme explains the formation of carbamide : (Enol form.) (Keto form.) the lower temperature being favourable to reaction (a), the higher to reaction (b), whilst biuret results from the interaction of carbamide and cyanic acid, as has been proved by direct experiment. A theoretical explanation of the formation of cyanuric acid and cyamelide respectively from cyanic acid was given, based on the existence in equilibrium of the two forms of the acid. The sub- limates formed when carbamide and biuret are decomposed by heat were shown to consist of ammonium cyanate and carbamide in variable proportions according to the experimental conditions, and the general impression that carbon dioxide is a product of the decomposition of carbamide by heat was shown to be unfounded; the vapours evolved consist solely of ammonia and cyanic acid, 117.‘‘Non-aromatic diazonium salts. Part I. Antipyrinedi-azonium salts and their azo-derivatives.” By Gilbert T.Morgan and Joseph Reilly. 1-Phenyl-2 : 3-dimethylpyrazolone-4-diazoniumchloride and the other diazonium salts previously described (P., 1912, 28,334) coupled readily with aromatic amines and the aliphatic P-diketo-compounds. I-Phenyl-2 : 3-dime thyl~rasolon e-4-nzo-P-izap7Lthylamine (m.p. 234-235O), unlike the purely aromatic azo-fl-naphthylamines, yielded intensely dark purple salts, stabIe in aqueous solution. 1 -Phenyl- 2 :3-dimethylpyrazolone -4-azoacetylacetone (m. p.181-182O) gave rise to an orange, sparingly soluble, sodium derivative, developing the enolic red coloration with ferric chloride, and yielding an olive-green copper derivative. Ethyl 1-phenyl-2 : 3-dimethylpyraaolone-4-azoacetoacetate(m. p. 174-175O) resembled the foregoing compound. The coupling of antipyrinediazonium salts and methyl acetylethyl ketone (acetylmethylacetone) was accompanied by the elimination of an acetyl group, so that the resulting condensation product, m. p. 199-200°, is derived from methyl ethyl ketone or dimethyl diketone (diacetyl), according as to whether it is to be regarded as an azo-derivative or a hydrazone. 134 118.“The fractionation of alloys and minerals in the electric micro-furnace,” By Arnold Lockhart Fletcher. An instrument-the micro-furnace-was described for a rapid qualitative and quantitative analysis of small quantities of alloys. The method described amplifies the classification of the more refrac- tory alloys (Turner, T., 1912, 101,585). ADDITIONS TO THE LIBRARY. I. Donatiom. Alchemical Society.
