SYNTHESIS OF HETEROCYCLIC AMINES VIA THE REACTION OF DIALKYLENE GLYCOL AND AMMONIA

摘要

This invention relates to an improved process fox producing morpholine and its derivates by reacting ammonia and dialkylene glycol. The improvement resides in continuously charging the dialkylene glycol and ammonia to a trickle bed reactor, operating the reactor under conditions such that the dialkylene glycol is maintained as a discontinuous liquid phase and the morpholine formed is predominantly in the vapor phase.
