A process for the continuous distillative separation of mixtures comprising morpholine (MO), monoaminodiglycol (ADG), ammonia, water and methoxyethanol (MOE), obtained by reacting diethylene glycol (DEG) with ammonia, wherein ammonia, water, ADG and DEG are removed by distillation and the resulting stream comprising MO and MOE is supplied to a distillation column Kin which at a top pressure of from 20 to 2000 mbar MO, MOE and organic products having a boiling point 128&#xb0; C. (1.013 bar) are removed via the bottom and organic products having a boiling point 128&#xb0; C. are removed overhead, and also MO is removed via a side draw, where Kis equipped with an evaporator for heating the bottoms, into which is fed heating vapor having a pressure of from 1 to 10 bar.

Method for the continuous separation by distillation of mixtures that contain morpholine (MO), monoaminodiglycol (ADG), ammonia, water and methoxyethanol (MOE)

A process for the depletion of 2-methoxyethanol (MOE) from a mixture comprising predominantly morpholine (MO) (crude morpholine), wherein crude morpholine is distilled in a distillation column in the presence of an alkali metal compound of the general formula M[RO] (Mis alkali metal cation and R is hydrogen (H), methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl or tert-butyl), where MO and a compound of the general formula R&#x2014;OH are distilled off and an alkali metal methoxyethoxide of the general formula M[MeOEtO] is obtained in the bottom of the column.
