Abstract

1378423 Methylene bridged polyarylamines IMPERIAL CHEMICAL INDUSTRIES Ltd 27 Dec 1972 [28 Jan 1972] 4045/72 Heading C2C In a process for the manufacture of methylene bridged polyarylamines by reaction of formaldehyde and a primary arylamine in the presence of a catalyst, the formaldehyde is added to the other components in a first mixing stage while continuously circulating the contents of the reaction vessel through an externally situated heat exchanger to apply cooling before isomerization occurs. The preferred catalyst is hydrochloric acid and the preferred primary arylamine is aniline.
