The Application of Electrochemical Technology in the Production of Ethylenediamine

摘要

The processing of the light fraction formed during the separation of amines for components by rectification is investigated. The light fraction which is an aqueous solution with about 1% of ethylenediamine and 2% of ammonia is treated in an electrolyzer with ion-exchange membranes. It is shown that a concentrated product containing about 118 g/1 of ethylenediamine, about 106 g/1 of ammonia and purified water can be obtained in this case. The concentrated product can be used at the initial stage of amines production.
