Abstract

1,095,448. 3 - Chloro - 4,4<SP>1</SP> - diaminodiphenylmethane. UNIROYL Inc. Nov. 22, 1965 [Dec. 23, 1964], No. 49451/65. Heading C2C. [Also in Division C3] The invention comprises 3-chloro-4,4<SP>1</SP>-diamino-diphenylmethane. It may be prepared from the mixture of 4,4<SP>1</SP>-methylenebis-(2- chloroaniline), 4,4<SP>1</SP>-methylene - dianiline and 3 - chloro - 4,4<SP>1 </SP>- diaminodiphenylmethane obtained by the acid-catalysed condensation of aniline, 2-chloroaniline and formaldehyde by dissolving the mixture in benzene, extracting the solution with acetic acid, treating the extract with ammonia and separating the solid 3 - chloro - 4,4<SP>1</SP>- diaminodiphenylmethane by filtering. It may be purified by recrystallizing from ethanol.
