A process for preparing EDDN and/or EDMN by conversion of FA, HCN and EDA, the reaction being effected in the presence of water, and, after the conversion, water being depleted from the reaction mixture in a distillation column, which comprises performing the distillation in the presence of an organic solvent which has a boiling point between water and EDDN and/or EDMN at the distillation pressure existing in the column or which forms a low-boiling azeotrope with water.

DMN的方法,包括在反应后,在蒸馏塔中从反应混合物中去除
水,其中包括在存在有机溶剂的情况下进行蒸馏,该有机溶剂在蒸馏压力下的沸点介于
水和EDDN和/或E
DMN之间,或者与
水形成低沸点共沸物。
