Process for the preparation of N-vinyl-N-alkyl-carboxylic acid amides

N-Vinyl-N-alkyl-carboxylic acid amides are prepared, starting from N-ethyl-carboxylic acid amides, in a 3-stage process consisting of the following stages: (a) anodic alkoxylation of the N-ethyl-carboxylic acid amides to give N-α-alkoxyethyl-carboxylic acid amides; (b) alkylation of these N-α-alkoxyethyl-carboxylic acid amides with an alkyl halide or dialkyl sulfate in an alkaline medium to give N-α-alkoxyethyl-N-alkyl-carboxylic acid amides; and (c) splitting off of alcohol from the products of stage (b) by heating to temperatures between about 60° and about 350° C. Instead of stages (b) and (c), it is also possible to carry out the following stages after stage (a): (b1) splitting off of alcohol from the N-α-alkoxyethylcarboxylic acid amides obtained in stage (a) by heating to temperatures of about 60° to about 600° C., to give N-vinyl-carboxylic acid amides; and (c1) alkylation of these N-vinyl-carboxylic acid amides by reaction with an alkylating agent of the same type as in stage (b) in an alkaline medium. The N-vinyl-N-alkyl-carboxylic acid amides obtained by the process are valuable intermediate products, in particular for the manufacture of homopolymers and copolymers with interesting properties.
