abstract |
The invention relates to a method for producing EDDN and/or EDMN by reacting FA, HCN and EDA, the reaction being carried out in the presence of water, and separating the water from the reaction mixture in a distillation column after the reaction, characterized in that distillation is carried out in the presence of an organic solvent which, at the distillation pressure prevailing in the column, has a boiling point between that of water and EDDN and/or EDMN or which forms a low-boiling azeotrope with water. |
