Abstract

1357256 Process for the production of imines SNAM PROGETTI SpA 24 Aug 1972 [10 Sept 1971] 39574/72 Heading C2C A process for the production of imines comprises passing a primary aromatic amine and a ketone through a synthesis zone constiutted by a fixed bed of molecular sieves, recovering from the effluent from the synthesis zone unconverted reactants and the desired imine, and regenerating the molecular sieves. The process is described with reference to a flow diagram and examples show the reaction of aniline and acetone to produce N-isopropylideneaniline and aniline and acetophenone to produce N-(α-methyl)benzylideneaniline.
