Abstract
PURPOSE: To increase the CN- ion concentration remarkably and obtain the titled compound useful as an intermediate for an epoxy hardening agent, etc. in high yield, by reacting isophorone with prussic acid in the presence of a basic catalyst and a glycol in a specific temperature range.
CONSTITUTION: Isophorone is reacted with prussic acid in the presence of a basic catalyst, e.g. Na, and a glycol, e.g. ethylene glycol, at 50W150°C, and an acid is then added to the reaction solution to neutralize the catalyst. The unreacted prussic acid and salt are then removed to carry out the vacuum distillation and separated the unreacted isophorone and give the aimed compound. The glycol to be used is inert to the isophorone and prussic acid and stable at a relatively high temperature and exhibits a high solubility in the basic catalyst. Dihydroisophoronenitrile mixed in the recovered isophorone will not deteriorate the isophorone, and the recovered isophorone is reusable as a reaction raw material.
