I. Notes of researches on the poly-ammonias

Abstract

In a note on the Action of Tetrachloride of Carbon on Aniline submitted to the Royal Society on the 17th of June, 1858, I have described a crystalline basic derivative of aniline formed by the coalescence of three molecules of ammonia, viz. carbotriphenyltri-amine, C 19 H 17 N 3 = (C 6 H 5 C iv H 2 ) 3 } N 3 , the formation of which is accompanied by that of a colouring matter of a magnificent crimson colour. It may be useful to quote here the passage of the paper referred to, in which the formation of the colouring matter is mentioned. “On submitting a mixture of 3½ parts by weight of aniline and 1 part of bichloride of carbon, both in the anhydrous state, for about thirty hours to a temperature of 170° C., the liquid will be found to be converted into a black mass, either soft and viscid, or hard and brittle, according to time and temperature.
