Abstract

PURPOSE: To prepare adipic acid in high purity and yield, without necessitating catalyst, low temperature, and high pressure, by the oxidative ring-opening reaction of cyclohexylamine with liquid nitrogen dioxide (N2O4) in a solvent at a temperature below the boiling point of N2O4.
CONSTITUTION: In the preparation of adipic acid by the oxidative ring-opening reaction of cyclohexylamine with liquid nitrogen dioxide (N2O4), the reaction is carried out in a solvent (e.g. dichloromethane, ethylene dichloride, bromoform, etc.) at a temperature below the boiling point of N2O4. The generated heat of reaction can be effectively removed by adding the starting compound dissolved in a solvent to liquid N2O4 or a solution of liquid N2O4 in a solvent; however, the reaction may be carried out by adding liquid N2O4 to the starting compound dissolved in a solvent.
