Abstract

321,580. Dyson, G. M., and Renshaw, A. Dec. 5, 1928. Salts of a urea derivative.-The neutral alkali salts of the urea of m-aminobenzoyl-m-amino-ptoluyl-1-naphthylamine-4 : 6 : 8-trisulphonic acid described in Specification 314,909 are purified by conversion into the lead salt using a soluble basic lead compounds such as lead acetate, decomposing the lead salt with mineral acid, and neutralizing the liberated acid with caustic alkali, alkali carbonate or ammonia. An example is given.
