摘要

1529118 4-Oxocapronitrile STAMICARBON BV 19 Aug 1977 [26 Aug 1976] 34951/77 Heading C2C 4-Oxocapronitrile is obtained by reacting acrylonitrile with excess acetone in the presence of a primary amine and/or a Schiff base, the process comprising maintaining the oxygen content of the reaction product at below 20 p.p.m. and distilling this reaction product at below 195‹ C. at atmospheric pressure or above in the presence of a solvent for 4-oxocapronitrile which is inert and has a boiling point of 80 to 195‹ C.
