    摘要: A transamination process is described to prepare polyamine product mixtures from reactants comprising mixed nitrogen-containing compounds with binary carbon spacing between nitrogen-containing groups (a binary component). A second nitrogen-containing component with a second carbon atom spacing between nitrogen-containing groups may also be employed. The molar ratio between the binary and second components can be adjusted to customize the product composition for desired end uses.

    摘要: Processes for the continuous fractional distillation of a mixture comprising morpholine (MO), monoaminodiglycol (ADG), ammonia and water from a reaction of diethylene glycol (DEG) with ammonia, the process comprising: (i) separating off ammonia from the mixture at a top of a first distillation column K10; (ii) feeding a bottom fraction from the first distillation column to a second distillation column K20, wherein water and an organic product are separated off at a top of the second distillation column at a top temperature of 45 to 198° C. and a pressure in the range from 0.1 to 15 bar; (iii) feeding a bottom fraction from the second distillation column to a third distillation column K30, wherein morpholine and an organic product having a boiling point of 190° C. (1.013 bar) are separated off at a bottom of the third ditillation column, and (iv) feeding the morpholine-comprising stream from the third distillation column to a fourth column K40, wherein morpholine is separated off at a side offtake of the fourth column, an organic product having a boiling point of ≦128° C. (1.013 bar) is separated off at a top of the fourth distillation column and an organic product having a boiling point of ≧128° C. (1.013 bar) is separated off at a bottom of the fourth distillation column.
