ABSTRACT:
This invention relates to an improved process for producing morpholine. The improvement resides in continuously charging the diethylene glycol and ammonia to a first trickle bed reactor, operating the reactor under conditions such that the diethylene glycol is maintained as a discontinuous liquid phase and the morpholine formed is predominantly in the vapor phase, separating the reaction products into a morpholine stream and a 2-(2,aminoethoxy)ethanol stream, and then charging the 2-(2,aminoethoxy)ethanol stream to a second trickle bed reactor and then reacting with ammonia to produce morpholine.
