摘要： An amine-containing mixture containing one or more amines, water, low-boilers and optionally high-boilers is fractionated by a process having the steps (iii) and (iv) and optionally the steps (i), (ii) and (v): (i) a (first) low-boiler fraction is separated off from the amine-containing mixture by distillation, (ii) a (first) high-boiler fraction is separated off from the amine-containing mixture by distillation, (iii) the amine-containing mixture is extracted with sodium hydroxide solution, producing an aqueous, sodium-hydroxide-containing first phase and an aqueous-organic, amine-, (further) low-boiler- and possibly (further) high-boiler-containing second phase, (iv) the aqueous-organic second phase, is distilled, producing essentially anhydrous amine as bottom-phase take off or sidestream takeoff in the stripping part of the distillation column, an amine/water azeotrop as sidestream takeoff in the enrichment part of the column and a (further) low-boiler fraction as overhead takeoff, and recycling the amine/water azeotrop to the extraction step (iii), (v) the essentially anhydrous amine is further purified of fractionated.
