Abstract

1396762 Preparation of imines from primary aromatic amines SNAMPROGETTI SpA 24 Aug 1972 [10 Sept 1971] 39573/72 Heading C2C The invention comprises a process for the preparation of imines in which a mixture of a ketone and a primary arylamine in which the aryl group is either unsubstituted or substituted by one or more substituents selected from halogen, OH, alkoxy or hydrocarbyl radicals, and, optionally, a solvent, is circulated through a vessel containing a fixed bed of molecular sieves capable of absorbing water but incapable of absorbing the reactants. Exemplified reactants are aniline, acetone, acetophenone and methyl ethyl ketone whilst the use of aniline/ methylisopropyl ketone, p - chloroaniline / acetone, p-methoxy aniline/acetone, p-hydroxyaniline / propiophenone and aniline / p - chloroacetophenone is mentioned.
