    Abstract: The invention relates to a method for separating a reaction product stemming from the reaction of EDDN or EDMN with hydrogen in the presence of THF and a catalyst that contains TETA or DETA, water and optionally organic compounds that have a higher or lower boiling point than TETA or DETA, characterized by a) adding the reaction product, once hydrogen was separated off, to a distillation column DK1 in which a THF/water azeotrope is separated off via the top, said azeotrope optionally containing other organic compounds having a lower boiling point than TETA or DETA, and in which column a bottom product which contains TETA or DETA is separated off, and ii) guiding the bottom product from stage i) to a distillation column DK2 and separating THF off via the top and removing a TETA- or DETA-containing stream at the bottom of the column, and iii) condensing the stream from stage i) removed at the top of the column DK1 and adding to the condensate or a part of the condensate an organic solvent, which is substantially immiscible with water, in such an amount that a phase decomposition takes place and separating the mixture so obtained in a phase separator, returning the arising organic phase, which contains THF and the organic solvent which is substantially immiscible with water, to the column DK1 and removing the aqueous phase.
