Abstract

1367629 N-Alkylsuccinimides IMPERIAL CHEMICAL INDUSTRIES Ltd 7 Dec 1971 [24 Dec 1970] 61327/70 Heading C2C N-Alkylsuccinimides are prepared by reacting a solution or slurry of succinic acid or its anhydride in a medium inert towards the reactants (and not water in the case of the anhydride) with a gaseous primary alkylamine, the molar ratio of amine to acid being at least 2 and of amine to anhydride being at least 1, and then distilling the reaction mixture to isolate the N- alkylsuccinimide. The reaction is preferably carried out at a temperature below the boiling point of the medium used (e.g. 30-90‹ C. for water) and when the starting material is the anhydride the distillation is preferably carried out in the presence of an acidic catalyst (e.g. ptoluenesulphonic acid). The Examples (1-4) describe the preparation of N-methylsuccinimide.
