METHOD FOR PRODUCING EDDN AND/OR EDMN THROUGH THE CONVERSION OF EDFA AND/OR EDMFA WITH HCN

摘要

The invention relates to a method for reacting ethylenediamine-formaldehyde adduct (EDFA) and/or ethylenediamine-monoformaldehyde adduct (EDMFA) with hydrogen cyanide (HCN) in a reactor with limited back mixing at a temperature in the range of 20 to 120°C, characterized in that the dwell time in the reactor is 300 seconds or less.
