摘要:

AbstractThe synthesis of 2,2‐bis‐(2,6‐dimethylbenzoyl)‐3,3′‐dimethylbenzyl is described starting from 2,6‐dimethylbenzoic acid. This substance appears to be identical with the condensation product obtained previously from 2.6‐dimethylphenyllithium and 2,6‐tetrame

摘要:

AbstractA derivation is given of the thermodynamic formulae for the double layer of AgI and of mercury electrodes. It is shown that there is only a quantitative difference in the treatment of the two systems and so one can use the obvious similarities to get a better understanding of the AgI system.

摘要:

AbstractThe U.V. absorption spectra of p.amino‐salicylic acid were measured both in water and in ethanol. The results of these measurements show that there is no discrepancy between the work ofWaya.o. andDraina.o. as was suggested by the latter authors.In addition the U.V. absorption spectra of some related compounds were measure

摘要:

AbstractPyrolysis of 1,1,1,3‐tetrachlorobutane at 450‐460° C gives 1,1‐dichlorobutadiene‐1,3; from 1,1,1,3‐tetrachlorohexane 1,1‐dichlorohexadiene‐1,3 was obtained.These new dienes have an ultra‐violet absorption maximum at 2430 and 2465 Å, respectively. They polymerize to viscous oils on standing, but do not react with maleic anhydride o

摘要:

AbstractThe action of aqueous nitrous acid on 2‐chloromethylpropene‐1 (methallylchloride) results in the formation of an unstable addition product which is converted into 1‐chloro‐2‐methyl‐3‐nitropropene‐1 upon treatment with alkali. For this new compound, the name nitro isocrotyl chloride is proposed. Its structure was established by ozonolysis, which yielded nitroacetone and hydrogen chloride.Dinitrogen tetroxide acts upon methallyl chloride to give a nitronitrite, which may be converted into a nitroalcohol upon treatment with methanol. This nitroalcohol has the probable structure formula 2‐chloromethyl

摘要:

AbstractSwelling experiments have been carried out with gelatin in solutions of the chlorides of the alkali and alkaline earth metals. In the alkaline earth metals series, swelling appears to increase with the equivalent conductance of the cations. The relationship is not linear. Calcium chloride and strontium chloride solutions give equal swelling values. With the alkali chlorides a more or less hyperbolical relationship was found between swelling and ionic radii. The water contents of gelatin swollen in sodium chloride, potassium chloride or rubidium chloride appear to be practically identical. Lithium chloride and caesium chloride give a higher water content.
