Abstract: A novel method, employing sodium methandate as the neutralizer for ethylenediamine hydrochloride is deve-l oped to extract hydrochloride. Because of the low boiling point of methanol, it is not only easier for separation and puri fication of ethylendiamine, but also lower for the energy consumption. By the operations of neutralization, desalination,dehydration and distillat ion, high purified enthylenediamine can be obtained with 94% productive ratio.

Key words: Ethylenediamine Hydrochloride, Sodium Methanolate, extracting Hydrochloride, Ethylenediamine
