Reaction Conditions:
with triethylamine at -5 - 25;Large scale;Temperature;
Steps:
1 Preparation of compound dN-benzyl-N-propenylacetamide
In a 8000L glass-lined reactor, 2300 kg of acetic anhydride was charged, 120 kg of triethylamine was added,Plus compounds 3080kg, about 6 ~ 8h, temperature control 3 , drop Bi warming to 23 , heat 2 ~ 3h, the reaction EndInto the other after 8000L glass-lined reactor, equipped with a 3m high and low tower distillation, heating decompressionDistillation, graded to receive triethylamine, glacial acetic acid and acetic anhydride, the residue in the reactor cooling in the compound N-benzyl-N-Acrylamide 3761 kg, GC = 95.6%, and the molar yield was 0.96 based on benzylamine.
