FIELD: machine building.
SUBSTANCE: electrochemical treatment of amine-chlorine-hydrate is performed in four-chamber electrolyser with ion-changing membranes at density of current 100-500 A/m. For this purpose the chamber of electrolyser next to a cathode chamber is filled with solution of amine-chlorine-hydrate for extraction of amine from it. Also, cathode and anode chambers are separated with cation exchanging membranes; while an anion exchanging membrane is set between the second and the third chambers of electrolyser. Amine is concentrated in the cathode chamber, and hydrochloric acid is concentrated in the chamber of electrolyser next to the anode one.
EFFECT: raised ecological safety of procedure, reduced power expenditure at extraction of amine.
