PURPOSE:To obtain the subject compound in high yield enabling an equimolar reaction of raw material compounds by using 1,3-dimethyl-2-imidazolidinone as a solvent and reacting isophorone with hydrocyanic acid in the presence of a basic catalyst. CONSTITUTION:3-Cyano-3,5,5-trimethylcyclohexanone is produced by reacting isophorone with hydrocyanic acid in the presence of a basic catalyst at 60-160 deg.C using 1,3-dimethyl-2-imidazolidinone as a solvent. The process enables the industrial production of the objective compound at a low cost in remarkably high yield at a molar ratio (isophorone/hydrocyanic acid) of 1. The compound is useful as a starting substance for the production of raw material for an epoxy resin hardener, a higher elastomer, a polyurethane coating, etc. |
