Abstract

1,229,695. Preparation of methylene bridged polyarylamines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 3 April, 1970 [17 April, 1969], No. 19634/69. Heading C2C. The invention relates to the manufacture of methylene bridged polyaryl amines which comprises condensing a primary arylamine and formaldehyde at elevated temperature in the presence of a neutral metallic salt, e.g. a halide of an alkali or alkaline earth metal in the absence of added acid. The condensation may be carried out at above atmospheric pressure and the process may be conducted in a continuous manner. Several examples are given.
