Abstract
N-substituted N-cyanocarboxylic acid amides are prepared by reacting 1 mol of an N-cyanocarboxylic acid amide salt with 1 mol of an alkyl halide or an alkylating agent, for example dimethyl sulfate or diethyl sulfate, in a polar aprotic solvent. The N-substituted N-cyanocarboxylic acid amides which can be obtained by the process according to the invention are useful curing agents for epoxide resins.
