Reaction Conditions

Reaction Steps

1071.5 Parts by weight (10 mol) of N-methylaniline and 15.0 parts by weight of Tonsil® K 10 are placed in a 3-neck stirred flask fitted with a reflux condenser and inlet tube. The mixture is heated to 120° C. and 265.3 parts by weight (5 mol) of acrylonitrile are added at this temperature via the inlet tube. The reaction mixture is subsequently stirred for 18 hours at from 120° to 130° C. and then cooled to 60° C. The catalyst is filtered off and the liquid phase is subjected to fractional distillation. 47.7 parts by weight of acrylonitrile and 620.9 parts by weight of N-methylaniline are recovered and can be used again as starting material. The yield of N-β-cyanoethyl-N-methylaniline is 605.0 parts by weight ~75.5% conversion. The purity is 99.5% N-β-cyanoethyl-N-methylaniline.
