Abstract

PURPOSE: To clean with ease a distillation column contaminated by solid matters without stopping the operation, by introducing a specific amount of water into the distillation column in motion as quickly as possible in the preparation of cyclohexanone, etc. from cyclohexane.
CONSTITUTION: Cyclohexane is submitted to air oxidation in liquid phase in the presence of foric acid to give a reaction mixture, from which unreacted cyclohexane is separated continuously by means of distillation to give cyclohexanone and cyclohexanol. In this operation, 0.1W0.5vol% of water based on the amount of the reaction mixture introduced per hour is added to the distillation column of cyclohexane in operation as shot a time as prossible (within 10min, preferably within 6min) to clean the distillation column. A position where water is fed is any position from the feed opening of the reaction mixture to the bottom of the distillation column.
