2940 U D L E S THE SWELLING AND DISPERSION OF CCCCVI1.-The Swelling and Di8persion of Some Colloidal Substances in Ether-Alcohol Mixtures. By ERNEST WALTER JOHN M~RDLES. IT is well known that cellulose nitrate and Kauri copal each dissolve readily in a mixture of ethyl alcohol and ethyl ether although the liquids taken singly are non-solvents and that the solubility o SO- COLLOIDAL SUBSTANCES IN ETHER-ALCOHOL MIXTURES. 2941 potassium stearate Sandazac resin or night-blue in such a mixture is greater than the mean value of the solubilities in either con-stituent. This characteristic solvent action appears to be general with a large number of colloidal substances and mixtures of liqUida, e.g. gelatin in water-acetic acid potassium oleate in alcohol-water, casein in pyridinewater but no satisfactory explanation of it appears yet to have been made.Baker’s view that in ether-alcohol mixtures the intrinsic solvent for cellulose nitrate is a loose molecular complex of alcohol and ether (J, 1912 101 1409) has been con-siderably criticised (Report of Discussion on Colloids held jointly by the Faraday and Physical Societies 1920). Barr and Bircum-shaw have proposed the hypothesis previously rejected by Baker, that the “ best solvent ” of cellulose nitrate is unimolecular alcohol. A close study of the phenomena in particular the gelation of the sols and swelling behaviour indicates that a complete explan-ation must involve the sigdicant fact that swelling precedes dispersion. The important bearing that swelling has on peptisation or dispersion in mixed liquids was recognised many years ago by Tompkins (op.cit. appendix 2) but his view that dispersion is an extreme case of what in lesser degree is known as swelling is now regarded as erroneous. It appears that the ether in an ether-alcohol mixture not only acts as a diluent disturbing the equilibrium (RoOH) nR*OH, but also actually enters the complex which the molecules of the dispersion medium form with the colloid.* Baker pointed out that when the ether is replaced by another non-solvent there is not necessarily formed a solvent mixture for cellulose nitrate. Although he was probably right in ascribing to the ether an active part in the solvent action yet his hypothesis as to the particular mode of action is not in accord with fact.It has been found as a general principle that the characteristic solvent action of mixed liquids cannot be ascribed to the intrinsic action of one kind of molecule or molecular complex but whenever molecular simplification occurs in a liquid mixture there is increased solvent action. Therefore when compound formation occurs between the components of a binary mixture loss of solvent power is to be expected. Indeed it is possible to use a colloidal substance, e.g. cellulose acetate to detect the presence of a molecular compound in a system of liquids (Mardles J. 1924 125 2244). The action of mixed liquids on colloids presents a number of striking features both with regard to swelling and to peptisation. If cellulose nitrate be soaked in dry ether or absolute alcohol there * Kugehwa (Rec.tmv. chim. 1922 41 751) has shown that ether favours the peptisation of cellulose dinitrate and alcohol that of the trinitrate. 5a 2942 BIARDLES THE SWELLING AND DISPERSION OF is little apparent change even if the temperature be vaned from - 80" to + loo" but a certain amount of swelling occurs. With the addition of the second liquid there is a rapid increase in the degree of swelling. For example a iilm of cellulose nitrate after immersion at the ordinary temperature for a few days increased 28% in weight in dry ether and 68% in absolute alcohol ; in ether containing 5% (vol.) of alcohol the increase was 75% and any FIG. 1.

The degree of swelling is expressed as the weight of the swollen mass obtained from 1 gram of the dry colloid. M&rials.-The ether was dried over sodium and fractionated.

The Zanzibar copal used was from the same sample throughout and the vulcanised rubber consisted of ordinary black rubber tubing extracted with acetone. The cellulose acetate (Rh6ne) had an acetyl content of 39.6%, corresponding with the formula C,,H,,O,(O*CO*CH,)S. The swelling results obtained for cellulose nitrate when dispersion did not occur seem to indicate that the degree of swelling in ether-alcohol mixtures tends to increase enormously with further additions of the second liquid. The experiments of M s o n who found that fibrous cellulose nitrate absorbed a maximum amount o 2944 MARDLES THE SWELLING AND DISPERSION OF ether-alcohol vapour when this was composed of 1 mol.of ether and 1 mol. of alcohol apparently support this view (op. cit. p. 95). It is significant that the optimum solvent mixture of alcohol and ether for cellulose nitrate has an equimolecular composition only when a little water is present. It contains more alcohol if the materials have been carefully dried (compare Stepanow 2. ges. Xchiess-u. Sprengsbflzu. 1907 2 43; Matteoschat ibid. 1914 9 105). The close relationship between the degree of swelling and solvent action is shown clearly in the case of the copal resins. Zanzibar copal one of the harder and more intractable copals swells con-siderably in ether-alcohol mixtures but the amount of dispersion is small.On the other hand $he softer Kauri resin dissolves in the mixtures and on cooling sufficiently either the solution gelates or the resin is precipitated as an amorphous mass. With Benguela copal of intermediate hardness a part of the resin is dispersed and the remainder swells considerably. The optimum solvent mixture, L e . the one which dissolves the resins most readily forming solu-tions that are most stable against precipitation by cooling or addition of diluents has practically the same composition as the mixture of liquids in which maximum swelling occurs in the case of the harder copals. The degree of swelling of Zanzibar copal reaches a maxi-mum when the proportion of ether is 70% by volume (Fig.l), and this mixture exerts the maximum solvent action on Kauri and Benguela copal (Fig. 2). The very marked influence of smelling on dispersion is also shown by the study of the binary mixture anisole-benzyl alcohol. Cellu-lose nitrate is swollen but not dispersed by this mixture and it is possible to plot the whole of the swelling curve. The swelling of cellulose acetate is considerable and dispersion occurs on warming, so it is possible to note the relation between degree of swelling and solvent action. Towards the copals this binary mixture behaves as the previous one (Table I and Fig. 3). The anisole used had d$ 0.989 and b. p. 155". Of the benzyl alcohol Po 1-043 95% distilled between 205" and 206". It is seen from Table I that the swelling of cellulose nitrate continues in anisole during the 31 days but becomes constant in some of the mixtures after 15 days.This fact that the rate of swelling is highest when the swelling is greatest is of importance in explaining why the " best " solvent mixture disperses the most rapidly; for not only does the optimum solvent mixtum often form the least viscous sol so that the resistance to the diffusion of the colloidal particles from the surface during dispersion is at a minimum but also the initial swelling of the colloid is most rapid SOME COLLOIDAL SUBSTANCES IN ETHER-ALCOHOL MIXTURES. 2945 TABLE I.

The swelling of cellulose acetate is at the maximum in the benzyl alcohol-anisole mixture containing 50% of anisole and Table I1 shows that this is also the optimum solvent mixture.

The addition of benzyl alcohol facilitated the dispersing action and the solutions were stable a t lower temperatures. The important influence of swelling on dispersion can be shown equally well with other binary mixtures e.g. alcohol and water.Knoevenagel and his co-workers (KoU.. Chem. Beiheft 1921 1922, 1923) have measured the swelling of cellulose acetate in a number of binary mixtures and the solvent action of many of these mixtures on the same substance has been determined (Mardes J .

There is a close correlation in most cases although different varieties of cellulose acetate were used.Gelatin and vulcanised rubber differ from the cellulose esters and the resins in that their degree of swelling in ether-alcohol mixtures is less than the mean value. The swelling of cellulose nitrate in phenol-anisole is quite different from that in benzyl alcohol-anisole there being no maximum to the curve. TABLE 111.

The solvent power numbers were obtained in the manner already described (J. 1924 125 2244). The explanation of the characteristic dispersing action of mixed liquids must be sought in the cause of the increased swelling and, FIG. 6.

Cellulose nitrate in an ether-alcohol mixture probably attaches to its particlea both kinds of molecules from the dispersion medium and these attracted molecules may bind additional ones. Esselen ( J . Id. Eng. Chem. 1920,12,801) discussing the charac-teristic solvent action of mixtures of chloroform and alcohol on cellulose acetate puts forward a possible explanation based on the fact that cellulose and its compounds have marked affinities for the hydroxyl group of alcohol. Mixtures of liquids containing as one constituent a substance with reactive groups such as an alcohol ketone or acid especially if this constituent is the h t 5 G 2948 U D L E S %!EX SWELLING AND DISPERSION OF member of a homologous series usually have markedly high solvent action.A liquid such as hexane or xylene which is not particularly reaetive and is a high member of a homologous series behaves like a diluent or inert component in a binary mixture. The structure of the complex formed by the molecules of the dispersion medium and a colloidal particle is apparently simple, for the composition of the best solvent mixture is often simple, molecularly (Mardles J. 1924 125 2244) and Knoevenagel has FIG. 6.

VScosity and Density of the.Sols.-The effect of the addition of a colloidal substance on the viscosity of a binary mixture of liquids is in general such that the shape of the viscosity-composition curve becomes exaggerated and any special feature of it is developed (Mardles J. 1924 125 2244). These effects are produced when cellulose nitrate is added to ether-alcohol mixtures (Table IV and Fig. 6).

Surface-ternion iKeumrements.-A large number of measurements of the surface tensions of the organosols in ether-alcohol mixtures and in the single liquids were made at different temperatures and for Merent concentrations by means of Sugden's maximum bubble pressure method (J. 1924 125 27). In the case of ethyl alcohol and its mixtures with ethyl ether benzyl methyl ether and anisole, the effect of the addition of the colloidal substance was to raise the surface tension of the dispersion medium. Similarly the ether organosols had higher surface tensions than the pure liquids. The temperature coefficient of the surface tension from 10" to 30" for the organosols was practically the same as that for the pure dispersion medium.Tables VI and VII give a selection of the results obtained.

A study has been made of the swelling and the dispersion action of ether-alcohol mixtures on colloidal substances. The explan-ation of the high dispersing action of the mixed liquids must be sought in the cause of the colloidal substances swelling initially to a greater extent in the mixtures than in the liquids taken singly, there being a close correlation between the swelling and the &-persing action. The attraction between a colloidal particle and the molecules of the mixed dispersion medium due to the presence of mutually reactive groups whereby compIexes are formed appears fo reach a maximum with certain combinations of liquids because of the special spatial arrangement and interlocking of the various molecules in the complex resulting from their size from the relative strengths of their affinity bonds etc. so that it is necessary in any explanation to consider the relative specific characters of the liquids and the colloidal substance. With increase in the solvent power of the liquid mixtures for cellulose nitrate the change in density increases and the sols become relatively less viscous. The surface tensions of the organosols are either the same as or slightly higher than that of the pure dispersion medium. BIRKBECK C~I;LEQE, UNIVERSITY OF LONDON. [Received J d y 27th 1926.

STOCKDALE !t'HE ALLOTROPY OF W C . 2961 CCCCVII1.-The Allotropy of Zinc. By DAVID STOCKDALFL THE work here described was undertaken in order to discover some sure means of recognising allotropy in metals at high temperatwet3 and of accurately determining those temperatures. The experiments of other workers those in which X-rays were used being left out of account may be divided into two groups 2952 STOCKDALE THE ALLOTROPY OF WNC. (a) Investigations of the physical properties of the metal quenched from temperatures above and below that of the suspected trans-formation point. (b) Experiments carried out in the neighbourhood of the transition point. Objection to the former experiments can be made on three grounds : (1) There is no certainty that during the quenching an allotropic metal does not revert to its original form.(2) During the chilling of even a small specimen very great stresses are created and these may cause false results to be obtained. (3) Very little is known about the phenomena of "lag" in allotropic changes at high temperatures. It is possible that this lag may be SO great that the temperature may be raised considerably above that of the transformation without any change taking place id the metal. The third criticism can be made of the latter group of experiments also which have consisted for example in investigations into the speciiic heats of metals a t high temperatures measurements of electrical resistance of thermal electric power and of the mechanical properties of the materials but the most serious objection is that these methods are not infallible.For example it has been shown by Miss Bingham ( J . Inst. Hetab 1920J24,333)-and confirmed by the author-that zinc undergoes an allotropic change between 310" and 330"; yet of all the physical properties of zinc only the electrical resistance and the " mechanical " properties are dehitely discontinuous through that range of temperature. Miss Bingham has shown that in the case of zinc the change in resistance is extremely small in comparison with the resistance. Attempts to carry out exact measurements with an ordinary tensile testing-machine would probably be futile. The problem to be solved was to devise some method of measuring the change in a property of a metal in such a way that this change would appear large with respect to the quantity measured just prior to the transformation.There is between a metal and an electrolyte in contact with it a certain difference of potential which is a function of the temperature. If the potential difference and the temperature be plotted the result may be a curve similar to A B (Fig. I). At the triple point (a-allotrope p-allotrope vapour) the solution pressure of the two forms must be the same and therefore if B represents the triple point, B must also lie on the potential difference-temperature curve (B C ) of the p-allotrope. But there seem to be no reason why the slope of A B and of B C should be the same and if exact measurements o STOCKDALE THE dIlL0TROPY OF ZINC. 2953 differences of potential could be made triple points of metals which exhibit allotropy could probably be detected by changes in direction of the curve.The effect would be increased by " lag "; that is fo say one form might exist in a metastable condition over a range of temperatures and then suddenly change into the other. If such were the case the curve would be of the form A B D E C and the triple point would be found by producing CE until it cut AD. By the use of this principle &hen (2. physikal. Chem. 1894 14 53; see also Roozeboom " Die Heterogenen Gleichgewichte vom Stand-C E L Tin€. T punkte der Phasenlehre," Vol. - .l-! ME. I- p. 123) was able to measure accurately the transition temperature of tin. If a second electrode of the metal is immersed in the electrolyte, and connected with the h t a small constant Uerence of temper-ature being maintained between them an electrolytic cell will be formed having a very small E.M.F.The E.2II.P.-temperature (or time) curve will be the algebraical difference between two curves such as A B C (Fig. I) and should have the form A B C D (Fig. 11), B and C representing the temperatures at which the allotropic change takm place in the two electrodes. If allowance is made fo 2954 STOCKDALE !l'€€E ALLOTROPY OF ZINC. " lag," the theoretical curve should be of the form A B E F C G H D (Fig. III) and by producing the lines G F and D H the triple point should be ascertainable. The order of magnitude of the E.M.B. and of the changes in it can be made the same by choosing a suitable temperature merence between the two electrodes.E X P E R I M E N T A L . As it appeared certain from the work of Miss Bingham that zinc undergoes allotropic change at about 30" it was thought advisable to test the foregoing theoretical conclusions by carrying out experi-menta with that metal before seeking such changes in others. The zinc used was " Brunner Mond's purest electrolytic." The choice of an electrolyte was limited because the liquid must not attack the zinc in any way either by oxidation or by deposition of a second metal on it and preliminary experiments had indicated that no gas must be given off when the electrolyte is heated. Finally, a mixture of zinc chloride containing much oxychloride with 10% of zinc bromide was used. It melted a t about 280". The apparatus consisted of a hard glass U-tube 1.5 cm.in diameter the limbs being 4 cm. apart and 22 cm. long. One limb was wound with nichrome ribbon protected from oxidation by pyruma cement and could be heated by passing a small current through the ribbon. The U-tube was placed in an electrical resistance furnace so that the limbs projected a distance of 5 cm. ; the empty portion of the furnace was lightly packed with asbestos fibre. The quantity of electrolyte was3 such that the level of the molten material was 6 cm. above the bottom of the tube. To stop convection currents, the connecting piece was lightly plugged with glass wool. The difEiculty arising through the molten zinc salts running up the hot tube and solidifying neaz the top was overcome by winding the tops of both limbs with nichrome ribbon and keeping them considerably hotter than the bottom parts.The zinc electrodes 0.4 x 0.4 x 6 cm. were attached to stout copper wires passing through the rubber stoppers closing the limbs. The stoppers were also fitted with rubber valves preventing access of atmospheric moisture. The copper wires were connected through a mirror galvanometer. In the circuit were a reversing key and an apparatus for opposing an E.M.F. to that generated by the little cell. The galvanometer threw a spot of light on a sheet of paper moving upwards at a uniform rate and by following the spot of light with a pencil it was possible to draw an E.2f.P.-time curve in a direct and easy way. Temperatures were measured by copper-constantan couple STOCKDALE THE ALLOTBOPY OF ZINC.2955 (size 30 gauge) sheathed in fine glass tubes and so placed that the hot junctions were about 1 cm. above the bottoms of the electrodes. The couples were used in conjunction with millivolt-meters standadbed by means of the melting points of pure Zinc, lead and tin. Before a series of experiments was begun the U-tube and its con-tentswere heated to 4Oo"to drive off any steam and to anneal the zinc. The tube was then heated or cooled at different rates through the range where the allotropic change might be expected to occur the two limbs being kept at slightly different temperatures and 23.M.F.-time curves were drawn. An attempt was made to read the milli-voltmetres every other minute. The apparatus described above is unsatisfactory and the ex-perimental difEculties are numerous.Firat a single operator has too much to do if he is to obtain correct results. Then there are troubles with the electrolyte. It was found impossible to mainbin a uniform temperature diflerence between the two limbs and con-sequently the curves obtained were not sharp. As the galvanometer was not sufficiently sensitive the breaks in the curves were very small and were liable to be completely obscured by small experi-mental errors. Sixteen curves in all were taken. The results obtained from eight of the more convincing experiments are in the following table t is the time (mins.) taken for the temperature to change from 300" to 330" and T the difference in temperature of the electrodes.

Experiment 8 hi which the rate of heating was fast is interesting in that the lag in the hotter electrode was so great that the point F (Fig. III) lay between the points C and G and the line F G was very short because the cooler electrode underwent the transformation almost immediately after the other 2956 BRI!LTON ELECTBOMETIUC STUDY OF THE REACTIONS The Sgurea in columns B and C show that there is a transition point at 315".It will be seen also that there is a "lag" at the r a b of heating employed but in no case was the measured " lag " very great. The largest values obtained were 7" below the mean temperature on cooling curves and 13" above the mean temperature on heating curves. It is quite possible that this phenomenon of " lag " may have been responsible for the many failures to obtain breaks in the curves. Fig. IV is an exact reproduction of the curve obtained in Experi-ment 4. In general the others resembled it ; in many cases how-ever the observed breaks were much larger and sometimes they were not nearly so regular in shape.Conclusion. The experiments indicate that zinc undergoes allotropic change at 315". This result agrees very well with those of Miss Bingham (Zoc. cit.) who found that changes occurred in some properties of zinc at about 330" and in others at about 310". The figures set out in the table seem convincing ; the curves from which these figures are derived are not convincing and the value 315" is to be accepted only with reserve. The author regrets that circumstances have arisen which make it impossible for him to continue this work. His conviction that the principle underlying his experiments is correct and that a further attempt to apply it both to theexaminationof zinc and of other metals will yield valuable results is his excuse for offering this paper for publication. In his opinion it is necessary to provide some means of confirming the existence of allotropic changes revealed by the use of X-rays. The author expresses his gratitude to Mr. C. T. Heycock M.A., F.R.S. for his interest and help and to the Royal Commissioners of the Exhibition of 1851 for a senior studentship. THE GOLDSBQTE~' METALLURGICAZ LABORATORY, UNIVERSITY OF CAMBRIDGE.

2956 BRETON ELECTBOMETIUC STUDY OF THE REACTIONS CCCCIX.-Electrometric study of the Reactions between Alkalis and Silver Nitrate Solutions. By HUBERT THOMAS STANLEY BRIPTON. PRECIPITATES formed by the addition of alkalis to metallic salt solutions are as a rule basic. Silver oxide however appears to be an exception and therefore its precipitation by sodium hydroxide has been studied BETWEEN ALKALIS AND SILVER NlTad!I!E SOLUTIONS. 2957 The precipitation of silver oxide from silver nitrate solution by ammonia and ite subsequent re-solution have been studied from variom points of view. h-escott (ch. New& 1880 42 31), Reychler (Ber. 1883 16 9W) Draper (Phamn. J. 1886 17 488), and Hem (2. awg. Chem. 1910 67,248) found that when approx-imately 2 mols. of ammonia were added to 1 mol.of silver nitrate the precipitate formed redissolved. That the substances in these proportions do enter into some kind of reaction has been shown by the following physicochemical methods cryoscopy and con-ductivity (Reychler Ber. 1883 16 2421; 1895 28 555) measure-ments of partial pressure of ammonia (Konowalov 2. physika2. Chem. 1898,28,558; Gans 2. a w g . Chm. 1900,25,236) thermo-chemical measurements (Berthelot and Delbpine Compt. rend., 1899 129 326; Bruni and Levi Gazzettu 1917 47 i 259) and transference number determinations (Whitney and Melcher J. Amer. Chem. Soc. 1903 25 70). The current view that silver exists in ammoniacal solutions as a complex kation each silver atom being associatsd with two molecules of ammonia originated in the work of Bodlhder and Fittig (2.physikul. Chem. 1901 39 597) who showed by an application of the mass law that the solubility of silver chloride in ammonia could be accounted for if the silver were assumed to pass into a complex ion Ag(NH,), the values of 2 actually varying from 1.67 to 2.22. Little appears to be known of the process of formation of the complex and consequently the experimente described in the second portion of this paper have been performed. EXPERIMENTAL. 1. Electrometric Titration with the Silver Electrode of Silver Nitrate with Sodium Hydroxide. The precipitation of silver oxide was studied by means of the following concentration cell the AgINIlO-AgNO serving as the standard half-element; the other silver electrode dipped in the solution which was being titrated : /lO-AgNO saturated 1100 C.C.of O-OZM-AgNOS 4. I KNO solution I + x C.C. of 0-1N-NaOH I The alkali was added very slowly and before each measurement was made the mixture w a thoroughly stirred. Steady and reproducible E.M.P.’s were readily obtained. The two electrodes made from the same piece of silver wire were fused into glass tubes so that lengths of 2 cm. were exposed and covered electrolytically with layers of finely divided silver from silver nitrate solution. Checked against a normal calomel electrode saturated potassium nitrate being used as junction liquid they gave a normal electrode potentia 2958 BRITTON ELECTRO~TIUC STUDY OF THE REACTIONS of 0-802 volt a t 20° in good agreement with the accepted value 0.80.

The dissociation of silver nitrate in N/lO-solution being taken as 81*4% Eh = 0.739 = a h + RT log [Ag*]/nF = ah - 0.063 ; and consequently s h = 0.802 volt. The precipitate formed during the addition of the h t 10 C.C. of alkali was white but immediately became brown. A little remained in colloidal suspension until 7 C.C. more than the theoretical amount of alkali had been added.

Silver nitrate in the precipitate would tend to become a '' solution link " (compare Thomas and Freiden J . Amr. Chem. Soc. 1923 45 2522) and its presence would account for some silver oxide remaining in colloidal solution. Much of the undecomposed silver nitrate was readily attacked as will be seen from the great change in silver-ion concentration which took place a t the point corresponding to the stoicheiometrica BETWEEN ALEALB AND slLvER NITRATE SOLUTIONS. 2959 amount of sodium hydroxide. There probably still remained a trace of u n a h k e d silver nitrate although too small to be shown in the diagram for the colloidal solution was not decomposed until 7 C.C.excw of. alkali had been added. This suggestion may account for the high initial values of the solubility product of silver hydroxide given in Table I. If the formatibn of such a colloidal solution is due to a stabilising influence tending fo increase the solubility of the dispersed particles such as may be created by the silver oxide particles containing some undecomposed silver nitrate it would be expected that silver hydroxide would be more soluble when 8 part of it is in colloidal soIution than when it is not. The silver-ion concentrations were calculated from the equation Eoba = - 0.063 - 0.058 log [Ag'] and the hydroxyl-ion concen-trations from the excw of alkali added complete dissociation being assumed.On introducing corrections for dissociation the solubility products are diminished by about 0.1 x 10-8 in every case.

Chem. 1903 46 521) found the value 1-52 x 10-8 from conductivity measurements a t ZOO and Jellinek and Gordon (ibid. 1924 112 212) the lower values 5.5 and 7-3 x lo3 from E.M.F. measurements of AglAg,O,zNaOH. The cause of the discrepancy between these two results and of their exceptional lowness can be traced to the erratic behaviour of the silver electrode in presence of silver oxide in alkaline solutions which Luther and Pokorny (2. a w g . Chem. 1908 57 290) and Buehrer (cited in Lewis and Randall's 'cThermodynamics,yy 1923 p. 483) who observed it are inclined to attribute to reduction of the silver oxide a t the expense of the electrode.The behaviour of the A@g,O,NaOH electrode during the titration may perhaps best be studied from a consideration of the voltages of the oxygen-hydrogen cell a several attempts have been made to arrive practically at its E.M.F. through measurement 2960 BRITTON ELECTROMETRIC STUDY OF THE REACTIONS of the silver electrode in question. Nernst and Wartenberg (2. physikd. Chem. 1906 56 534) found by extrapolation from the results obtained in their classical researches on the dissociation of steam a t high temperatures that the potential difference of the oxygen-hydrogen cell at the ordinary temperature could be cal-culated from the expression E.M.F. = 1.232 - 0.00085 (to - 17), and therefore the E.M.F. a t 20" should be 1-229 volts.G. N. Lewis ( J . A ~ T . Chem. Soc. 1906 28 158) calculated that the P.D. of O,~aOH,Ag,O~g is 0.049 volt at 25" from the dissociation pres-sures of silver oxide a t high temperatures which have since been confirmed by Keyes and Hara (ibid. 1922 44 479) the essential assumption being that no allotropic change in the silver oxide takes place on heating. Hence the E.M.F. of 0,l- IIT being 1-229 volfs a t 20" and calculation showing that the E.M.F. of OflaOH,Ag20pg a t 20" is the same as at 25" the E.M.F. of A&g,O,NaOHIR should be 1.180 volts a t 20". Using Bottger's value of the solubility product of silver hydroxide at 25" Lewis calculated that the P.D. a t 25" of the last combination should be 1.168 volts and consequently that of the oxy-hydrogen cell should be 1.217 volts.Converted by means of the temperature coefficient given in Nernst and Wartenberg's equation these P.D.'s become 1-172 and 1-221 volts at 20" respectively. Luther and Pokorny (Zoc. cit.) found by direct experiment that the initial voltage of AgJAg,O(electrolytically prepared),NaOHIH was 1.172 volts a t 25" (i.e. 1.176 volts at 20"). Table I1 gives the P.D.'s of the AgCAg,O,NaOHIH combination calculated for various stages of the titration from which the E.M.F.'s of the oxygen-hydrogen cell were obtained by adding 0.049 volt (vide supra).

On correcting for ionisation the values become 2 to 3 millivolts less negative.The first two P.D.'s of the oxygen-hydrogen cell are greater than the value 1.229 volts found by Nernst and Wctrfenberg (h. cit.). The discrepancy may be due to a slightly increased solubility of the silver oxide through some having been in colloidal solution, and possibly also to some extent to the fact that precipitation had only just ended and consequently any reduction which might have taken place would be a t a minimum. Save for the h t two values the E.M.F.'s of the AgcA@;,0,Na0m2 range from 1-163 to 1.170 volts. The average value 1.167 volts is 13 millivolts less than the one given by Nemt and Wartenberg 5 mv. less than that of Lewis and 9 mv. less than the initial value of Luther and Pokorny for electrolytic silver oxide.R d a m (2. phgsikul. Chem. 1921 99 474) has determined the P.D.'s of many cells AglAg,O,alkalilH, in which both barium and sodium hydroxides werelemployed and also samples of silver oxide which had been subjected to a variety of treatments. With precipitated oxides the E.M.F.'s varied from 1-137 to 1-155 volts a t 25" or from 1.141 to 1.159 a t 20° the higher values being obtained with those oxides which had not been separated from the solutions from which they were precipitated. On the other hand by electro-lysing a sodium hydroxide solution between a platinised platinum kathode and a silver anode he found that after the current had been flowing for a few minutes the E.M.F. measured immediately after it was stopped varied between 1.171 and 1.177 volts a t 25" (ie.1-175 to 1.181 volts a t 20°) the kathode becoming in effect a hydrogen electrode. The highest value agreed with the value extrapolated from the work of Nernst and Wartenberg and Lewis. The values given in Table I1 of the E.M.F.'s of the A@gzO,NaOHP2 fall between those indicated by Rmdam's measurements. It is significant that the highest value for pre-cipitated oxides corresponding to 1.159 volts a t 20" indicated by Rdam's work was obtained with silver oxide which had not been removed from the solution in which it was precipitated. The higher E.M.F.'s of the present author may be due to the fact that they were measured within a few momenta of precipitation. If the lowness of the AgcAg,O,NaOH results is due its suggested by Buehrer and Luther and Pokorny to reduction it would appear that the higher values obtained in this work were due to reduction having taken place to a smaller extent than in the experiments of R d m 2962 BRITTON ELECTROMBTRfC STUDY OF THE REACTIONS Strangely enough R d a m attributed the low resulfs given by precipitated oxides as compared with those given by the electro-lytic oxide to the existence of twb different modifications of saver oxide having different dissociation pressures and by means of the Nernst heat theorem he calculated the transformation tem-perature to be 132".For the purpose of calculation he took 1.143 volts a t 25" to be the E.M.P. of AglAg,0(precipitated),NaOHlH2 in spite of the wide variation in his experimental values uz'x.from 1.137 to 1.155. He considered that the precipitated oxides were the forms stable below 132" and that the electrolytic oxide was metastable a t the ordinary temperature but stable above 132". For this reason the method adopted by Lewis in his calculation of the P.D. of OJNaOH,Ag,O~g was held to be inadmissible. This hypothesis does not account for the E.M.F.'s found in this work which as already stated lie between those obtained with the two supposed forms of silver oxide. The variable results obtained with the Agpg,O,alkali electrode especially after standing for some time appear to be best accounted for by reduction. The low solubility products obtained by Jellinek and Gordon (bc. cit.) were probably due to this cause especially if the exceptionally low values of the extrapolated P.D.'s of the AgCAg,O,NaOW cell be considered in one case 1.150 volts a t 20" and in another 1.139.TABLE 111.

Chem. 1903 46 1) on which this calculation was based wm 1.140 VOh thereby accounting for t,he low value of the solubility product BETWEEN ALKALB AND SILVER NITRATE SOLUTIONS. 2963 The solubility products given in Table I when considered in connexion with the E.M.F.'s of the Am20,NaO% com-bination appear to be lower than would be expected from the fundamental calculations of Nernst and Wartenberg and Lewis. Had the electrode been satisfactory the potential dif€erence of the combination should have been 1.229 - 0.049 = 1.180 volts a t 20", from which it follows that [Ag'][OH'] = 2.78 x 10-8 at 20".The theoretical potential difference of A&g20,H,0p2 a t 25" is 1-176 volts which gives [Ag'][OH'] = 2-74 x 10-8 a t that temperature. Analytical determinations of the solubility of silver oxide have given widely differing results which were dependent on the length of time allowed for the attainment of equilibrium and on the method of preparation of the oxide. Whitby (2. anorg. Chcm., 1910 47,107) found that at 20" silver oxide required 14 days to attain equilibrium with water. Table 111 gives a comparison of the results obtained a t 20" and 25" by chemical and physical methods. The solubility products have been calculated on the assumption that the dissolved silver oxide was completely ionised.At both temperatures the data obtained by direct analysis are higher than those obtained by physical methods. This may perhaps be partly due to incomplete dissociation of the silver oxide. The variable results obtained by E.M.F. methods show that these are unsatisfactory. The author's value a t 20" is probably low and yet agrees with that of Bottger. Bottger's value a t 25" was used by Lewis in his fundamental calculation of the E.M.F. of the oxygen-hydrogen cell and contrary to the contention of Rmdam, the low value he obtained is probably thus accounted for. 2. Electrmtric Titrations of Silver Nitrate with Ammonium Hydroxide by meam of (a) the Oxygen Electrode and (b) the Silver Electrode. Although the oxygen electrode is affected by the presence of silver oxide it can be used to indicate any pronounced changes in hydrogen-ion concentration which may take place when alkalis are added to silver salt solutions (this vol.p. 2148). The change in hydrogen-ion concentration occurring during the formation of the silver ammonia complex from silver nitrate and ammonia has there-fore been followed with its aid. 0-02M-Silver nitrate (100 c.c.) was titrated with 0-1027N-ammonium hydroxide a t 18" the oxygen electrode and the normal calomel electrode being used with saturated potassium nitrate solution as junction liquid. In Fig. 2 the observed E.M.F.'s are plotted against the quantities of ammonia added. The propor-tiond hydrion scale afied to the diagram is based on colorimetri 2964 BRITTON ELECTBOMETRIC STUDY OF THE REACTIONS measurements by GiUespie’s drop-method ( J .Amer. Chem. Soc., 1920,42 742) of the hydrion concentrations of the solution a t the beginning and the end of the titration. The scale showed hydrion concentrations a t various stages of the titration which were in accord with those given by indicators. The curve shows that the h t drop of ammonia produced a sudden increase in pH and that precipitation began when 1 C.C. had been added. The addition of more ammonia cawed a further diminution in hydrogen-ion concentration until the (approx. 9) C.C. of 0.1027N-NH,OH was reached a t which silver oxide is normally precipitated. The change thereafter waa a gradual one until 1 mol. of ammonia (per mol.of silver nitrate) had been added; a small but definite idlexion then occurred and was followed by another when 2 mob. of ammonia had been added. At this stage the precipitate had completely dissolved. Draper (Zoc. cit.) noted that solutions con-taining the reactants in these proportions were strongly alkaline to turmeric and phenolphthalein i e . above pE 8. It might be imagined from the nature of the curve that the first section corresponding to the addition of the first mol. of ammonia, represents the complete precipitation of silver oxide and the second section its reaction with one mol. of ammonia to form a solubl monoammino-silver complex. The precipitation however was far from complete during the h t part ; and if a little but suflicient, nitric acid had been added to a silver nitrate solution treatment with ammonia produced no precipitate.Moreover moist silver oxide is readily soluble in ammonium nitrate solution and in an amount that suggests the formation of &NO,,NH,. The silver oxide precipitated on mixing equal volumes of NflO-silver nitrate and N/lO-sodium hydroxide dissolved completely at room tem-perature in quantities of N/2O-ammonium nitrate corresponding to the ratios 1 mol. AgOH 1-1-14 mols. NH,NO,. The solutions had pa about 8 and did not decompose on boiling. The silver-ion concentration of the solutions was comparatively large e.g. a solution composed of 20 C.C. of 0-1N-sodium hydroxide 20 C.C. of 0.1N-silver nitrate and 45 C.C. of 0-05N-ammonium nitrate con-tained 33.5% of the total silver present as silver ions.This may have been due to the presence of a highly dissociated monoammino-silver complex or of some silver nitrate and some diammino-complex. ReychIer (Ber. 1883 16 990) and Draper (Zoc. cit.) found that ammonia if added in small quantities caused partial precipitation of silver oxide from silver nitrate solution. In order to study this reaction more fully the percentage amounts of silver oxide pre-cipitated a t different stages of the titration were determined. The results are in Table IVY and are shown diagrammatically in Fig. 2. TABLE IV. C.C. of Ppted. Ag,O &s percentage 0.1027N- Mols. NH,OH/ Ag,O pptd. of the amount theor. NH,OH. Mols.

It appears that although the solution had attained the % neces-sary for the precipitation of silver oxide another reaction was taking place which withdrew from the solution some of the silver ions that ordinarily would have been precipitated. This may be seen from curve B in Fig. 1 which represents the titration of 100 C.C. of 0-02bl-silver nitrate with N/lO-ammonia with the aid of the silver electrode carried out at 18" in the same way as the sodium hydroxide titration. The portions of the curves A and B correspond-ing to the addition of the first 15 C.C. of alkali are almost identical in spite of the partial precipitation produced by the ammonia."hi 2966 BRITTON ELECTROMETRIC STUDY OF THE REACTIOXS indicates that silver ions were being removed from solution mainly owing to complex formation. A small inflexion occurred when 1 mol. of ammonia had been added. Calculation from the data of Figs. 1 and 2 shows that the product [Ag'][OH'] became less and less during the addition of the second molecule of ammonia; when the addition mas complete its value was 0.6 x 10-8 which is less than the solubility product of silver hydroxide and thus accounts for the re-solution. The main inflexion occurred when 2 mols. of ammonia had been added. Bruni and Levi (aazzetta 1917 47, i 259) made among their measurements with the silver electrode, four on solutions containing less than 2 mols.of ammonia for 1 mol. of silver nitrate. Their results show that a sharp diminution in silver-ion concentration takes place when between 1.5 and 2 mols. of ammonia have been added. The inflexion (Fig. 2) which occurred when 1 mol. of ammonia had been added may probably be accounted for by the fact that at that point the precipitation reaction stopped and consequently the destruction of hydroxyl ions ceased. The slight inflexion in the silver-ion curve (By Fig. 1) may be due to the two reactions, taking place during the addition of the first molecule of ammonia and causing precipitation and complex formation being followed by complex formation only which effects solution of the precipitate. An attempt has been made to account for the silver-ion concen-trations measured during the addition of the first 2 mob.of ammonia. The reactions were assumed to be (1) AgNO + NH,OH + AgOH + NH,NO, and ( 2 ) AgNO + 2NH3 e Ag(NH,),NO,. The amount of ammonia required for the precipitation of the silver oxide having been subtracted from the total amount of ammonia added the remainder was regarded as having been converted entirely into the complex salt Ag(NH3),N03. The concentration of silver nitrate originally present being known the concentration of unchanged silver nitrate could be calculated. The results are in Table V. The concentrations of free ammonia given in the last column were calculated from the expression [Ag'][NH3l2/ [Ag(NH,),'] = 2-2 x 10-8 (vide infm). TABLE V. NH,OH added. - Mols.per mol. of C.C.

The dissociation comtant of ammonium hydroxide being taken as 2.3 x 10-5 the hydroxyl-ion concentration in equilibrium with the free ammonia present when 2 mols. had been added was and therefore fi was 10.5 as compared with 10.2 shown by the scale in Fig.2. If it be assumed that the concentration of ammon-ium nitrate in the solution when 1.5 mols. of ammonia had been added was equivalent to the amount of silver oxide precipitated, it can be shown that the amount of free ammonia 4.5 x lo*, should have produced pH 9.3 (9.6 ; Fig. 2). The hydrogen-ion concentration prevailing in the earlier part of the titration was undoubtedly controlled by the hydroxyl ions originating from the precipitated silver oxide. The effect of a little nitric acid in a silver nitrate solution in preventing the precipitation of silver oxide with ammonia appears to be due to the depressing iduence of the ammonium nitrate on the ionisation of the ammonium hydroxide. It thus seems probable that the complex silver compound ultim-ately formed required 2 mols.of ammonia for its formation. The results in Table VI refer to the solutions which contained ammonia in excess of 2 mols. For the purpose of calculation the ammonia in excess of 2 mols. was assumed to be in the uncombined state, the small dissociation of the ammonium hydroxide wm disregarded, and the complex silver salt was taken as being completely dis-sociated thus Ag(NH3),N03 =e= Ag(NH3),' + NO,'.

2970 NOTES NOTES. Preparation of p- Bromophenylhydroxylamine by the Emulsijication Process. A Modi$cation. By ROBERT DOWNS HAWORTH and ARTHUR LAPWORTH. IT has been found that the reduction of pure p-bromonitrobenzene is often quite unsuccessful if carried out as previously described (J. 1921 119 770). The following modification of the original method however usually gives a yield of p-bromophenylhydroxyl-amine nearly the same as that originally obtained but involves the use of more solvent benzene and preferably also more reducing solution. It is essential that the sodium sulphide crystals used in making the reducing solution should be of good quality. p-Bromonitrobenzene (5 g.) benzene (40 c.c.) the hydrosulphide solution (120 g. prepared as formerly described Zoc.cit. p. 769), and calcium chloride (5 g. in a little water) are emulsified. Crystals soon separate and after 1 i hours solid ammonium chloride (5 g.) is added the whole shaken and the precipitated p-bromophenyl-hydroxylamine (about 2-9 g.) collected and washed with water. The benzene layer of the filtrate is separated washed with wafer, dried over anhydrous sodium sulphate and carefully diluted with petroleum (b. p. 40-60"); a further crop (about 0.5 g.) of the hydroxylamine is then obtained. Three experiments carried out in the above way gave total yields of 2-7 g. 3.4 g. and 3.3 g. respectively of p-bromophenylhydroxyl-amine. With the smaller quantity (52 g.) of sodium hydrosulphide solution previously advised the yields in five experiments were 24-34 g.-THE UNIVERSITY M~NCHESTER.[Received November 24th 1925. NOTES 2971 Action of Hydrazine Hydrate on Phenanthraquinone. A Corre.ectim. IT was stated by Dutt and Sen (J. 1923 123 3420) that phen-anthrone is the sole product obtained from phenanthraquinone by the action of hydrazine hydrate. In subsequent experiments with commercial hydrazine hydrate (50%) 9 10-dihydroxyphen-anthrene (m. p. 147") waa almost exclusively obtained instead of phenanthrone. Fortunately a small quantity of the original " hydrazine hydrate " in a sealed tube was available and this was found to be incorrectly labelled the substance being actually pure anhydrous hydrazine. Further experiments have shown that when anhydrous hydrazine is allowed to react with phenanthraquinone in absolute alcohol phenanthrone is obtained in good yield and that when small quantities of moisture are present or when ordinary com-mercial hydrazine hydrate is employed 9 10-dihydroxyphen-anthrene is almost the sole product.The error was made through unavoidable circumstances but is none the less regretted.-kPERrAL COLLEGE SOUTH KENSINGTON, S.W. 7.

COMPOUNDS of the aluminioxalate type derived from the acid H,Al(C,O,), should be capable of resolution into optically active forms. This has been attempted by means of active bases. Strychnine AZuminiozdzte.-Barium aluminioxalate (Burrows and Walker J.1923 123 2738) twice cryatallised from water was warmed with the calculated quantity of aqueous strychnine sulphate. The precipitate of barium sulphate and strychnine aluminioxalate was extracted with boiling water and the extract allowed to crystallise. Different crops had [aE. -24.0" to -21.0" in 50% aqueous acetone and formed slender colourless needles very sparingly soluble in water [Found strychnine 63.0; C,O, 16.6. (C21€&O~2),,H&l(C204)3,16H,0 requires strychnine 63.4 ; C,O,, 16-7%]. When these salts were recrystallised partial decomposi-tion occurred with formation of strychnine oxalate and aluminium hydroxide and no conclusions can be drawn in connexion with any rotational differences observed. When a solution of sodium aluminioxalate was treated with half its equivalent of aqueous strychnine hydrochloride a salt was obtained which had [a%* -19.0" in 50% aqueous acetone.It was treated with aqueous potassium iodide and the precipitated strych-VOL.

The resulting solution of potassium aluminioxalate contained a trace of colloidal aluminium hydroxide, and what optical measurements were possible pointed to the inactivity of the solution. Crystallisation of strychnine aluminioxalate from acetone gave crops of salt having slightly different specific rotations but consistent results could not be obtained. 1-Menthylamine A1uminiomlate.-The barium salt was digested a t 100" with an aqueous solution of the equivalent quantity (10 g.) of I-menthylamine previously dissolved in the calculated quantity of dilute sulphuric acid.SdEcient water was added to keep all the menthylamine salt in solution and after fltration from barium sulphate 17 g. of 1-menthylamine aluminioxalate separated in well-defined prisms which were sparingly soluble in water [Found: I-menthylamine 59-2 ; C204 33.6.

Recrystallisation which was accompanied by partial decomposition gave no evidence of resolution. Treatment of a concentrated solution of sodium aluminioxalate with one-third of the equivalent quantity of 1-menthylamine sulphate gave a salt having a rotation practically identical with the above. 1-Phenylethylamine A1urniniomlate.-This salt was prepared by digesting the barium salt with the calculated quantity of aqueous I-phenylethylamine sulphate at 100" for about an hour removing the barium sulphate and evaporating to a small bulk under diminished pressure.It crystallised from water in which it was very soluble in colourless prisms. The main bulk of the salt had [a]$* -340" in aqueous solution [Found C,O, 39-1. requires C204 39-1y0]. After it had been recrystallised four times from water its rotation was not measurably affected (Found: I-phenylethylamine 53.0 ; C,04 39.2. Calc. I-phenylethylamine, 53.7 yo). Distrychnine potassium aluminioxalate and d-phenylethylamine dipohsium alurninioxahte were also prepared. Their specific rotations did not change as a result of repeated recrystallisation. Cinchonsine aluminioxulate was obtained as a gummy solid which could not be crystallised.

OBITUARY NOTICES. 2973 OBITUARY NOTICES. RICHBRD BURTLES. BORN MAY 25m 19OO; DIED JULY 3RD 1925. RICHARD BUBTLES was the younger son of the late Alderman Richard Burtlea of Manchester. He was educated at Manchester Grammar School and at the College of Technology Manchester. He obtained the BSc. Tech. degree in July 1921 being placed in the Grst (Honours) division and was awarded a Manchester Education Committea Research Scholarship. This enabled him to devote a year to research during which he carried out an investigation on the tautomerism of the diphenylglyoxalines by which he earned the M.Sc.Tech. degree. He was then given a maintenance grant by the Department of Scientific and Industrial Research and investig-ated the preparation of 2-aminoglyoxalines and their behaviour towards nitrous acid.The patience skill and enthusiasm which he showed in these researches led to his appointment in July 1924, aa the writer's research assistant. In January 1925 he took a position aa chemist to the Goodrich Rubber Company Ltd. of Leyland and held this position until his death which was due to a bicycle accident. Burtles was elected a Fellow of the Chemical Society in May 1923, and published three papers jointly with the writer in the Journal (1923 123 361; 1925 127 581 2012). He was greatly inter-ested in stained glass no doubt owing to the fact that his father had been a glass manufacturer and contributed articles on " The Colouring of Medkeval Glass " and " The Decay of Ancient Glass " to the Journal of the blanchter University Science Federation (1923 2 i 18; 1924 2 ii 62).He took a useful part in the social life of the college becoming Secretary of the Manchester University Science Federation and also of the College of Technology Chemical Society and was very popular with the staff and students. During his school career Burtles underwent training for military service in the Officers Training Corps and reached the rank of lieutenant but owing to his age he was not called upon to serve a broad. Burtles married Vera daughter of C. E. Chalmers Esq. of Wellington Salop in July 1924 and leaves a son born a few days after his death. F. L. W. 6H 2974 OBITUARY NOTICES. REGINALD ARTHUR JOYNER. BORN JANUABY IOTH 1887; DIED OCTOBER 7TH 1925. DR. R. A. JOYNER lost his life as the result of an accident on Wednesday October 7th 1925 through an explosion in the research laboratories of Messrs.Nobel’s Explosives Co. Ltd. Dr. Joyner studied a t University College Bristol taking a London degree with Honours in Chemistry in 1909 followed by the M.Sc. degree of the newly-founded University of Bristol in 1910. His work during this period is recorded in three papers on amalgams of silver and tin published in the Journal of the Chemical Society. These exhibit his careful and thorough experimentation and stand unaltered. They form the accepted basis of the treatment of dental amalgams in modern courses on Dental Metallurgy. Joyner proceeded as an 1851 Exhibition Scholar to Zurich and afterwards followed Bredig to the Technische Hochschule Karls-ruhe where he qualified for the degree of Doctor of Engineering, which has seldom been obtained by students from abroad.Bredig recognised his exceptional ability and independent judgment. Joyner published two very neat experimental papers; one dealt with the afhity constant of hydrogen peroxide; the other on the catalysis of camphorcarboxylic acid by bases in various solvents, further elucidated the remarkable parallelism between ordinary reactions and life processes showing a mechanism through which optical activity may play its well-known r6le. For 12 years Dr. Joyner served on the Research Staff of Messrs. Nobel’s at Ardeer. Most of the important work which he carried out on such war-time problems as mustard gas and explosives is, of course not available for publication but an estimate of his unusual experimental skill and scientific acumen may be obtained from a study of the paper which he published in the JourmZ of the Chemical Society on the “ Viscosity of Solutions of Cuprammonium.” His skill in the field of chemical technology is well illustrated by his patented process for the continuous manufacture of hydrazine (Brit.Pat. No. 199750 of 1923). Those who came in contact with Joyner must have realised that few scientists showed such whole-hearted devotion and enthusiasm. He had many other interests having been versatile in athletics and a keen territorial officer for many years. His straightforward and unassuming personality gained him not only esteem but also affection from all who knew him. In spite of the tragedy of his loss at the age of thirty-eight his widow and three children can look back with pride on his devoted work in the cause of science.J. W. McB OBITUDY NOTICES. 2975 GUGLIEUWO * KORNER. BORN APRIL 2oTH 1839; DIED MdscH 2 9 r ~ 1925. GUGLIELMO Komm was born in Cassel on April 2Oth 1839. Having completed his come at the Polytechnic he decided to devote himself to chemistry and studied under Will Kopp and Engelbach a t Giessen where he graduated in 1860. He remained at Giessen as assistant for 3 years and shortly after spent a year as student under Kekul6 a t Ghent. Early in 1865 he became assistant to Professor Odling at St. Bartholomew’s Hospital; but at the end of the year returned to Ghent as private assistant and secretary to Kekul6 remaining there until the end of 1867 when the latter was elected to the chair of chemistry a t Bonn.At this time Kekul6 was engaged in developing his theory of the aromatic compounds and in preparing his treatise on the same subject and with this work Korner was closely associated. It is well known that Kekuld regarded his theory merely as a philosophic system which c o ~ e ~ t e d in a simple fashion the many isolated facts of aromatic chemistry and served as a useful means of explain-ing their relations; but he failed to grasp to the full extent its practical consequences. Korner with a clearer and broader out-look foresaw the possibility of establishing the theory on a sound experimental basis. During his stay at Ghent Korner found time to carry out a number of researches the most important of which were “the synthesis of reaorcinol” and one entitled “Faits pour servir ii, la d6termination du lieu chimique dans la s6ie arornatique,” published in 1867.In the preface to the former he points out that KekulB’s theory involves two problems not yet solved. He says, “Dam 1’8tude des cas d’isomerie dam les substances aromatiques on peut cons6quemment se poser deux problhmes principaux: on peut d’abord chercher B Btablir par exfirience quels sont les corps de m6me constitution c’est-&-dire dans lesquels la substitu-tion se fait 21 des places correspondantes; on peut ensuite sptkifier davantage ces places en cl~rchant par d i e n d’atomes d’hydrogh eUes aont sdpar&s entre dh. Dans sa plus grande gh6ralit6 ce dernier problhme pourrait s’appeler la d6termination du lieu Chirnique de l’atome substituant.. . . La solution du second problhme parait it premihre vue inaccessible B l’exp6rience. Je pense toutefois qu’on pourrait y parvenir.” He embodies here the idea which * KiSrner waa christened Wilhelm and strictly speaking should bear that Christian name ; but as he lived most of his life in Italy and never returned to his native laud and was known by and published under the name Guglielmo, it txems right 80 to designate him [To face p. 2976. 2976 O B m A R Y NOTICES. underlay his life’s work. In the same paper he brought forward a new fact in support of KekuI6’s theory for he succeeded in adding to the few di-derivatives then known in three isomeric forms a new and third iodophenol.In the second paper published in 1867 he gives an indication of the principle upon which his method of orientation is based. “ Sup-pose,” he says “ that the three dihydroxybenzenes give the same trihydroxybenzene by the introduction of a third hydroxyl it is obvious that the three hydroxyls must occupy the positions 1 2 4. In short it is only this arrangement of the three hydroxyls which can combine in one compound the three dihydroxy-derivative..” It must be remembered that a t this time methods of orientation were largely speculative.* It is true that by a fortunate act of intuition Baeyer assigned the correct constitution to mesitylene and Graebe gave the true formula to phthalic acid; but on the other hand some of the suggestions were less happy.Quinol for reasons into which we need not enter was assumed to be an ortho-compound salicylic acid a meta-compound and ordinary dinitro-benzene a para-compound and so forth assumptions which subse-quently led to ever increasing confusion as relationships became more clearly and closely established. For reasons of health Korner left Ghent for PaIermo in 1867 and entered the laboratory of Cannizzaro where he continued to work indefatigably collecting fresh experimental facts connected with the problem which he had set out to solve. In the two years which followed this material had so far accumulated that Canniz-zaro induced Korner to publish it although the latter would have preferred to withhold it until it had reached a more complete form.This memoir which involved a stupendous amount of brilliant experimental work appeared in 1869 in the Giornale d i Scienze Naturdi ed Econmniche of Palermo under the title “ Facts which serve for the determination of the chemical position in aromatic compounds.” After a short introduction by Cannizzaro the memoir begins with a clear account of KekulB’s theory on the constitution of benzene and the kinds of isomerism to which it gives rise. Korner shows that the non-existence of more than one monoderivative and the special kind of isomerism existing among the polysubstituents of benzene is based on the hypothesis of the equivalence of the six valencies of the carbon atoms of the * An excellent account of the development of the views on orientation is given in Roscoe and Schorlemmer’s “ Treatise,” vol.iii part iii (Introduction) and also in the introduction by Richard Meyer to Erlenmeyer’s “ Lehrbuch der organischen Chemie,” vol. ii (Leipzig 1882) OBITUARY NOTICES. 2977 nucleus and the relative positions occupied by two or more sub-stituent elements or groups. He then proceeds to bring expen-mental evidence of the equivalence of the six atoms of hydrogen. Beginning with the three hydroxybenzoic acids he shows that by eliminating carbon dioxide the same phenol results. Thus the differences in the three acids must be due to the relative positions of the groups. By substituting chlorine for hydroxyl and replacing the halogen by hydrogen with the aid of sodium amalgam he ob-tained the same benzoic acid in all three cases.These experi-mental facts due partly to Korner and partly to Graebe and Beil-stein demonstrate completely the equivalence of three pusitions in the nucleus. A fourth position was determined as follows the nitroaniline (para) of Arppe can be transformed into chlorobromobenzene in two ways either by substituting chlorine for the amino-group and bromine for the nitro-group or vice uersa and the same product results. As this nitroaniline can be proved to belong to the same series as one of the hydroxybenzoic acids it follows that the position occupied by the phenol residue in the three acids is equivalent to that in a fourth position corresponding to the amino- or nitro-group in nitroaniline. The fifth and sixth positions were attacked in a similar fashion.One of the nitrophenols belongs to the same series as salicylic acid. A bromine atom and an additional nitro-group can be introduced into this nitrophenol with the result that the product is identical with that obtained by substituting two nitro-groups for two atoms of hydrogen in bromophenol and thus bromonitro-nitrophenol C,H,~NO,~Br~OH*NO, is identical with dinitro-brm-pknol C,H,~NO,~NO,*OH~Br which signifies that in nitrophenol there are two positions of equal value and symmetrical one with the other in respect of the hydroxyl. There are therefore five equivalent positions. Granted the existence of two symmetrical positions and imagining a plane drawn at right angles through the centre of these two positions the molecule will be divided into two symmetrical halves which implies the existence of a second symmetrical pair and’% may be therefore concluded that the six positions occupied by hydrogen in the molecule of benzene axe of equal value.Unfortunately the publication in which this paper appeared was little known to the chemical world and it was only later that its full sigmficance was realised and its conclusions accepted. Meanwhile as already stated the confusion which reigned on the subject of orientation continued to grow. Whilst at Palermo Korner sent a paper to the Academie de 2978 OBITUARY NOTICES. Sciences on the “Synthesis of a base isomeric with Toluidine,” which he obtained by nitrating and reducing p-bromotoluene. The paper is interesting from the fact that in it he proposes the formula for pyridine which is now adopted.His reference to this formula was however suppressed in the paper sent to the Academie, probably from its purely theoretical nature but was afterwards published (1869) as a note in the G w m l e d i Scienze Natu~ali ed EconOmiche. We will l a v e for a moment Korner’s experimental work in order to take up the thread of his subsequent career. In 1870 the ‘‘ Scuola Superiore di Agricoltura ” was founded a t Milan and Korner was elected to the chair of organic chemistry, where he continued with his usual energy to prosecute his experi-mental studies. In 1874 his classical memoir on “Studi sull’ Isomeria delle cose dette Sostanze Aromaticee a shi atomi di car-bonio” appeared in the Gazzetta Chimica Itulianu in which is collected a mass of new material the preparation of which had occupied him during the preceding five years.He begins by explaining the weak points in the views of previous observers on orientation and shows that the only satisfactory method is the one outlined in his paper of 1867. “ For more than six years,” he says “ a number of distinguished chemists have occupied themselves with the study of isomerism of the so-called aromatic compounds and still continue to do so. Nevertheless it is a curious fact that no definite solution has up to the present been reached.” “ The most certain method I still believe to be the one suggested seven years ago in my first work on this subject namely the trans-formation of the three isomeric di-derivatives into the isomeric tri-derivatives .” He suggests then the utilisation of the three dibromobenzenes as affording the fewest experimental difficulties.“The equivalence of the six positions of hydrogen in benzene being granted it sufEces to prepare any complete series of tri-substituted derivatives with these three compounds and to study their relation and in this way an unequivocal solution of the problem will be attained. Thus by preparing the three possible tribromo-benzenes from the dibromobenzenes and discovering for each one of them how many and which of the tribromobenzenes can be prepared or vice versa finding from the latter to which of the dibromobenzenes it gives rise a direct and definite method will be afforded for determining the structure of both the di- and tri-bromobenzenes according to the following scheme : Further he says OBITUARY NOTICES.2979 I 4 Br A I I \/ Br Br f)Br Br 1:3:4 \/ 1:3 fir \/ Br Br 1:3:4 1:3:5 1:2:3 1:2 !,,!Br Br /\ Br / /\Br I )Br ()Br Br \/ Br 1:2:4 1:2:3 = L:3:4 In the same way it is possible to prepare the six modifications of dibromoaniline and also the six nitrodibromobenzenes.yy The principle as we know is simple elegant and beyond criticism and has never been seriously questioned. We have only to survey the number and variety of new com-pounds new reactions and new and ingenious devices for obtaining the same substance by Merent methods to realise the amount of patient and careful work and experimental skill which this truly classical research entailed.As his fellow-worker and biographer Professor Menozzi has said, “the work suEices fo raise Korner to a distinguished position among the peak chemists.” In addition to devising a method of orientation independent of any speculation Korner was able to lay down certain rules of substitution which possess not only a scientifk interest but one of great practical value. Putting it very briefly he showed that if the halogens or nitric acid act on the halogen derivatives of benzene or on aniline phenol or toluene so that one atom of hydrogen is substituted the principal product is the 1 4-derivative and as a secondary product the 1 2-derivativeY and the more violent the reaction the larger the quantity of the latter. Where the original group is CO,H NO, or SO,H the principal derivative is a 1 3-compound and at the same time a certain amount of 1 2- and occasionally 1 4-derivative is produced.If sulphuric acid is allowed to act on the members of the above series the product is mainly the 1 3-derivative with smaller and variable quantities of the 1 2-derivative. At the end of the paper Korner discusses KekuIB’s formula for benzene with the alternate double linkages. He shows that the simultaneous formation of 1 2- and 1 4-derivatives in certain cases and of 1 3-derivatives in others cannot be explained b 2980 OBITUARY NOTICES. Kekulb’s formula. He proposes one which had already been indicated in a former paper and resembles that of Clam inasmuch as each atom of carbon is linked with three others.This arrange-ment presupposes the twelve atoms to be disposed in four parallel planes; in each of the outer planes are three atoms of hydrogen I 3 5 and 2 4 6 and in each of the inner planes three atoms of carbon. This arrangement affords the maximum symmetry, represents absolute equivalence of the hydrogen atoms and the three cases of isomerism among the di-derivatives. Besides his work on the constitution of benzene to which he devoted the greater part of his time and thought his deep interest in botany led him to the study of many vegetable substances. Between the years 1875 and 1895 he published a series of papers dealing with products of the vegetable kingdom such as the con-stitution of veratric acid and veratrole the conversion of aspartic into fumaric acid on two acids isomeric with vanillic acid on caffeic acid from cinchona cuprein on the alkaloids of angustura bark the constitution of siringina and in collaboration with Menozzi on the transformation and synthesis of amino-acids.By the action of methyl iodide on amino-acids in presence of alkali, ammonia is eliminated and an maturated acid results thus aspartic acid gives fumaric acid alanine is converted into acrylic acid and leucine into an unsaturated acid containing six carbon atoms. The reverse process was also investigated and carried to a successful issue. Of Korner’s personal character Professor Angelo Menozzi a former student and collaborator has given his impressions in a memorial address from which the following abstracts have been taken.* The first thing that strikes one he says is that Professor Korner possessed in an eminent degree that quality of the true scientist who devotes himself to the study of science for its own sake, independently of any practical application his discoveries may be found to possess.It so happened that Korner’s discoveries though of scientific importance of the h t order have brought in their train practical results of great value. Korner belongs to that group of scientists who affirm nothing without a rigorous and complete proof and are never in a hurry to publish results. This quality he possessed in an excessive degree. It is certain that it took some pressure on the part of Cannizzaro to persuade Korner to publish his first paper on orientation.Furthermore the con-* I wish here to express my indebtedness to my friend Prof. Nasini for the many documents relating to K6mer which he wm good enough to place at my disposal and also for the photograph which is reproduced here OBITUARY NOTICES. 2981 stitution of orcin had been established in Korner’s laboratory before Tiemann’s research appeared in the Berichte. The same is true of leucine the constitution of which was fully known before its publication elsewhere. He recognised this weakness in him-sell but as it was of secondary importance to his work he put it aside as a matter of small sigmficance. Whilst one cannot but regret this excessive caution which led him to control with scrupulous care every conclusion and statement before publication and which may have robbed him of priority in certain discoveries one cannot but admire a quality which is only too rare among scientific workers of the present day.Korner possessed a keen intuition which was soon recognised by those with whom he worked. He declared the acid isolated from aspartic acid to be fumaric acid long before its identity was dehitely established and the same thing occurred with caffeic acid from angustura. As a teacher Korner was lucid profound and effective and his lectures left a lasting impression on the many students who attended his classes. His method was largely based on experimental demonstrations and Cannizzaro relates that when acting as lecture assistant his arrangement of the experiments was a model of precision and ingenuity.He was skilled in analysis by the dry way and insisted on his students becoming proficient in this method. In the execu-tion of his own researches in his skill as an experimenter in the originality of his idem and in the novelty of his methods he showed a master mind. He had a passion for preparing his specimens in a state of extreme purity and it is this personal characteristic which is responsible for that remarkable collection of organic substances which is one of the scientific treasures of the School of Agriculture of Milan and is unique in the variety purity and beauty of the preparations. Korner’s system of imparting information was essentially practical, for he never forgot that he w&s teaching in a school of agriculture. If a substance was connected with plant life-he was a passionate lover of flowers and plants and possessed a profound knowledge of plant physiology-he never failed to enlarge upon this relation ; similarly any reference to an industrial commodity led to an account of ifs technical application.He completed his 75th year in 1914 when according to the existing rule he reached the retiring age; but at the instance of fhe staff of the agricultural school supported by the Chemical Society of Milan his services were exceptionally retained until 1922 when for reasons of failing health he resigned his chair at the advanced age of 83 2982 OBITUARY NOTICES. He lived his last three years in peaceful retirement happy in his family life and in the visits of his former colleagues and pupils, and passed quietly away on the evening of March 29th 1925.Korner was elected honorary member of many Italian and foreign institutions wiz. the Reale Accademia dei Lincei the Reale Istitufo Lombard0 di Scienze e Lettere La Societit Italiana delle Scienze received the honorary doctorate of Oxford Cam-bridge and Giessen was awarded the Davy medal of the Royal Society and made honorary member of the Royal Institution of the Chemical Society of London and of the German Chemical Society. He was enrolled chevalier of the civil order of Savoy for work of scientific merit. J. B. COHEN. GEORGE DOWNING LIVEING. BORN DECEMBER 21ST 1827; DIED DECEMBER 2 6 ~ ~ ~ 1924. BY the death of Dr. G. D. Liveing Professor of Chemistry in the University of Cambridge a t the great age of ninety-seven the Society loses its oldest member as he was elected Fellow in 1853.He was the son of Edward Liveing of Nayland Suffolk. Entering a t St. John's College Cambridge he was eleventh wrangler in 1850 and in the following year he took the Natural Sciences Tripos then instituted for the first time and obtained a first class with distinction in Chemistry and Mineralogy. After working in Berlin with Rammelsberg he was elected to a fellowship a t St. John's College in 1853 but under the Statutes of that period he had to resign on his marriage in 1860. After acting as Deputy to the Professor of Chemistry (Reverend J. Cumming) he was elected to the Chair in 1861. It is difEcult to convey an idea of the attitude of the University a t this period towards the experimental sciences steeped as it was in the tradition of centuries of classical mathematical and theo-logical teaching.There was no laboratory instruction for students, although some experiments seem to have been shown in the lectures. Liveing relates how in 1850 he was attending Mr. Griflin's lectures on Physical Optics and whilst dealing with the subject of the Fraunhofer lines the lecturer askkd any who wished to come again later and he would demonstrate their formation. Liveing was the only one in the class who accepted the offer. The apparatus consisted of Wollaston's arrangement for producing a pure spec-trum. A prism a lens a slit illuminated by an oil lamp and a screen. Between the lamp and the slit was placed a bottle con [Po face p . 2982.OBITUARY NO!CIcEs. 2983 taining some copper turnings on which nitric acid waa poured. A series of ~e black lines appeared on the screen. The explanation of the formation of the black lines was not given by Bungen and Kirchoff until 1860. Liveing had to fight a long and hard battle to persuade the University that it was their duty to teach the experimental sciences not by merely showing experiments on a lecture table but by the only sure method of making the students perform them themselves. St. John‘s College soon after Liveing took his degree built him a chemical laboratory and “sowed the fmt seed towards the growth of a large chemical school,” and they allowed him to use this laboratory after he became Professor of Chemistry. The question of providing teaching in experimental sciences had still to be fought out.Plans were drawn up but when the tenders came in they far exceeded the money the University had to spend. The laboratory proposed for Chemistry by Professor Willis consisted of ‘‘a building which was capable of standing violent explosibns and as uninflammable as possible containing a aeries of vault^.^' Liveing would have none of this and begged that Chemistry should be left out of the scheme. The result of his action was that Chem-istry was only housed in a temporary structure for many years until in 1887 a laboratory was built on the Pembroke Street site. This building was added to in 1908 and again in 1920 and the department of Physical Chemistry has also taken over the large laboratory vacated by the Engineering department.Altogether the laboratory has accommodation for more than 700 research and ordinary students and is the largest chemical laboratory in the country. Liveing’s contributions to science were on the transmutation of the elements in 1855 and a few papers on geological and chemical subjects. In 1875 Sir James Dewar was appointed Jacksonian Professor of Chemistry and the two professors almost at once began their researches on the spectroscope which continued until 1904. These papers have been collected in one large volume and published by the University Press (1915). The work mas charac-terised by its great accuracy originality and the patience with which one difllculty after another was overcome and is now regarded as one of the standard books on the subject.As a lecturer Liveing was inspiring to those who had sdicient mathematical ability to follow him. The lectures were illustrated by experiments carefully chosen and invariably rehearsed but the experiments not unfrequently failed from his over-anxiety to make them succeed. As the head of a large department he maintained a stern discipline and to the younger men he appeared somewha 2984 OBITUARY NOTICES. unapproachable. Those who knew him intimately however were aware that he was the kindest and most liberal of men and a delightful companion especially wheh he was in the mood to tell stories of byegone Cambridge and of his travels during which he collected specimens of minerals to illustrate his lectures. Liveing in addition to his professorial duties found time to attend with great regularity the magisterial bench and many philanthropic and benevolent committees.For several years he held a commission as captain in the Town and County Rifle Corps; he was also an enthusiastic gardener. It is not generally known that for the last four years of his life he was actively engaged in an experimental investigation on the absorption of radiant energy by dense substances such as barium sulphate lead sulphate cassiterite litharge etc. Each vacation he devoted an hour or two every day to working at these problems in the Goldsmiths’ metallurgical laboratory and he spent much time a t home in working out his results. This research is far from complete although it is an amazing testimony to his vigour and perseverance.It was whilst on his way to the laboratory that he met with the accident which caused his death a few weeks later. Liveing resigned his professorship in 1908 and was given the degree of Sc.D. C. T. HEYCOCK. ALEUTDER MITCHELL WILLIAMS. BORN SEPTEMBER 20TEC 1888; DIED FEBRUARY 21ST 1925. THE son of a master-baker Alexander Mitchell Williams was born on September 20th 1888 at Burntisland in Fifeshire. He attended Burntisland School and later George Watson’s College in Edinburgh, where at the age of seventeen he was dux and gold medallist. With the John Welsh mathematical bursary (a foundation of Thomas Carlyle in memory of his father-in-law) Williams entered the University of Edinburgh and had a brilliant record in Mathematics, Physics and Chemistry.In 1910 he graduated as B.Sc. and as MA. with first-class honours in Mathematics and Natural Phil-osophy. During his University period he gained many scholar-ships and prizes being awarded finally an 1851 Exhibition Scholarship which enabled him to proceed to Sweden and work under the guidance of Arrhenius. His chief study in Stockholm was adsorption a subject which occupied his attention for many years afterwards. On returning to this country he continued research work in the laboratories of Professor Donnan in Liverpoo OBITUARY NOTICES; 2985 and in London. In 1915 he was appointed science teacher in Hawick High School and while there had a seriom breakdown in health from which he never entirely recovered. After temporary service in the Science Department of his old school in Edinburgh, he became a lecturer in the Chemistry Department of Edinburgh University in 1916.Continuing his research work he graduated as DSc. with a thesis on Adsorption. In 1919 he was appointed joint Head of the Physico-chemical Department a t the Shirley Institute Didsbury the headquarters of the Cotton Industry Research Association. Soon after his appointment he married Miss May Shaw an Edinburgh lady. While in Edinburgh William published four valuable papers on adsorption (“ Thermodynamics of Adsorption,” Proc. Roy. 8oc. Edin. 1918 38 23; “ The Adsorption Isotherm at Low Concen-trations,” ibid. p. 48; “ The Adsorption of Gases a t Low and Moderate Concentrations,” Parla I and 11 Proc. Roy. SOC. 1919, 96 A 287; Part 111 ibid.p. 298) together with one on “ Periodic Precipitation,” jointly with Miss M. R. Mackenzie (J. 1920 117, 844) and a paper on the “ Depolarisation by Oxygen of a Voltaic all” ( J . soc. Chem. Ind. 1920 39 28511). The work of Williams at the Shirley Institute was chiefly con-cerned with the moisture relations of cotton and the swelling of cotton cellulose under the influence of alkalis. The results of his researches are published in the JcrurnaZ of the Textile Institute. He showed that the swelling in mercerisation cannot be simply referred to the concentration of the hydroxide ion in the alkali solutions but is dependent to some extent on a specific effect of the alkali metal. The work so far published may be regarded as a considerable instalment of a systematic account of the nature and reactions of the cotton gel-an account which when complete, should give to those who use cotton in the textile arts increased powers in manipulating their material.One positive technical success Williams achieved by his discovery of a method for pre-paring cotton yarn of high insulating power so making it possible for English firms to compete in a trade which had long been a continental monopoly. Williams had a first-rate scientific intellect both critical and constructive. He was a sympathetic and kindly teacher and his investigations like all that he did were carried out with an energy and a fervour of enthusiasm which the state of his b d y health could ill support. A final attack of his insidious malady at the end of 1924 led to his untimely death on February 21st 1925.J. W 2986 OBITUARY NOTICES. GEORGE YOUNG. BORN SEPTEMBER QTH 1867; DIED APRIL 3RD 1925. GEOB~E YOUNG the younger son of Archibald Young surgical instrument maker was born in Edinburgh on September 9th 1867. He was educated in Edinburgh at the Collegiate School George Watson’s College and Mint0 House. He pursued the study of chemistry a t the Polytechnik Munich and graduated in 1891 at the University of Erlangen. Soon after returning home he was appointed demonstrator of chemistry at Firth college Sheffield, and was afterwards promoted to the lectureship in organic chemis-try a post which he filled with eminent success. Young was an excellent teacher and was most successful in interesting students in research. He contributed many papers on organic chemistry to this Journd between the years 1895 and 1905 dealing with the constitution of amidines the action of ammonias on acetyl urethane, triazoles and their derivatives and kindred subjects. He was a Fellow of the Chemical Society of the Institute of Chemistry and a member of the Society of Chemical Industry. In his school days Young was well h o r n in athletic circles as a good sprinter. At Firth College he took a lively interest in the life of the College; he started a students’ Chemical Society and at the outbreak of the Boer war he played a vigorous part in organising a company of students which was attached to the West Yorkshire Royal Engineers. He served with marked success as sergeant-major to the company. Young severed his connection with the College in 1904 owing to ill health and moved to London in 1906 where he established a consulting practice. During the Great War he directed his energies to industrial problems with a view to the production of chemicals formerly imported from Germany. Dr. Young died on April 3rd 1925 leaving a wife and three daughters to mourn his loss. w. c. w

FORMULA INDEX. THE following index of organic compounds of known empirical formula is arranged according to Richter's system (see Laikon dcr KoUemtoJ- Verbi?u€ungen). The elements are given in the order C H 0 N C1 Br I F S P and the remainder alphabetically. The compounds ere arranged-Firstly in groups according to the number of carbon atoms (thus C1 group, C group etc.). Secondly according to the number of other elements besides carbon contained in the molecule (thus 5 IV indicates that the molecule contains five carbon atoms and four other elements). Thirdly according to the nature of the elements present in the molecule (given in the above order). Fourthly according to the number of atoms of each single element (except carbon) present in the molecule. Salts are placed with the compounds from which they are derived.The chlorides, bromides iodides and cyanides of quaternary ammonium bases however are registered as group-substances, C1 Group.
