The Synthesis of Certain Aromatic Succinic Acids.

Abstract

Silver salt is an insoluble white powder, darkening slightly upon exposure to light. I t gave 34.40 prr cent. .4g; calculated, 34.24 per cent. We have attempted to saponify the cvanogen group of this compound and thus obtain thc tricarboxylic acid but it has resisted all attempts. Neither potassium hydroxide nor h!,drochloric acid in a sealed tube gave thc desired result. Wc. cxpect to investigate the character of this nitrogen atom and the salts of the acid more fully, as well as the exact constitution of the anhydride from which it was formed.
