    Abstract: PROBLEM TO BE SOLVED: To provide a method for fractionating an amine-containing mixture. SOLUTION: According to circumstances, (i) a (first) low boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, according to circumstances, (ii) a (first) high boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, (iii) the amine-containing mixture is subjected to extraction using a sodium hydroxide solution to produce a sodium hydroxide-containing aqueous first phase and an amine-, (further) low boiling point matter- and, according to circumstances, (further) high boiling matter-containing water-organic second phase, (iv) the water-organic second phase is distilled to produce a substantially anhydrous amine as a column bottom phase taken-out substance or as a lateral flow extract in the stripping part of a distillation column, an amine/water azeotropic mixture as a lateral flow extract in the concentration part of the column and a (further) low boiling matter fraction as a column top extract and the amine/water azeotropic mixture is returned to the extraction process (iii) and, according to circumstances, (v) the substantially anhydrous amine is refined or fractionated.

    Abstract: Separation of mixture of amine(s), water, low-boiling fraction and optionally high-boiling fraction includes optional distillative separation of low and high-boiling fractions, extraction of mixture with aqueous sodium hydroxide solution; and distillation of resultant aqueous-organic phase to recover anhydrous amine(s) from sump or side in separation part of column and amine/water azeotrope. Separation of a mixture containing amine(s) (I), water, low-boiling fraction (II) and optionally high-boiling fraction (III) comprises: (i) optional distillative separation of a first low-boiling fraction; (ii) optional distillative separation of a first high-boiling fraction; (iii) extraction of the mixture with aqueous sodium hydroxide (NaOH) solution, giving a first aqueous phase containing NaOH solution and a second aqueous-organic phase (IV) containing amines, other low-boiling fractions and optionally other high-boiling fractions; and (iv) distillation of the aqueous-organic phase to recover anhydrous amines as sump discharge or side discharge in the separation part of the column, an amine/water azeotrope, which is recycled to (iii), as side discharge in the concentration part and further low-boiling fraction as top discharge.
