Abstract

A process for the preparation of 2,2,6,6-tetramethyl-4-piperidone, from ammonia and acetone, characterized in that the acetone and the ammonia are reacted in a single step for a time of 2 to 8 hours in a molar ratio acetone: ammonia from 20: 1 to 4: 1, at a temperature of 50º to 120ºC and at a pressure of 1 to 50 atmospheres, in the presence of 0.001 - 0.1 moles of acid catalysts per mole of acetone used in the reaction.
