    Abstract: The invention relates to a method for the continuous separation by distillation of mixtures that contain morpholine (MO), monoaminodiglycol (ADG), ammonia and water, obtained by reacting diethyleneglycol (DEG) with ammonia. The method according to the invention is characterized by separating ammonia at the head of a first distillation column K10, feeding the product from the bottom of the column K10 to a second distillation column K20 in which water and organic products are removed at the head of the column at a head temperature ranging from 45 to 198°C and a pressure ranging from 0.1 to 15 bar, feeding the product from the bottom of the column K20 to a third distillation column K30, said column K30 being a divided wall column (TK) that has a partition wall (T) in the longitudinal direction of the column forming an upper common column section (1), a lower common column section (6), an inlet section (2, 4) having a rectification section (2) and a stripping section (4), and an outlet section (4, 5) having a rectification section (3) and a stripping section (5). The product from the bottom of the column of K20 is fed in the upper and middle third of the feed section (2, 4), based on the number of theoretical plates of the feed section, ADG and organic products having a boiling point > 190 °C (1.013 bar) are removed via the bottom of the column, the organic products having a boiling point ≤ 128 °C (1.013 bar) are removed via the head of the column, and the MO is removed from the middle and lower third of the outlet section (3, 5) (side stream), based on the number of theoretical plates of the outlet section.
