Conversion of ethylene diamine dihydrochloride into ethylenediamine by electrodialytic water-splitting

Abstract

The feasibility of water-splitting electrodialysis for the conversion of polyammonium salts into the corresponding amines and acids was demonstrated with the conversion of ethylenediamine dihydrochloride as an example. Two- and three-compartment cells were compared and their current efficiencies ascertained. The former was relatively low in current efficiency, with a roughly linear increase with conversion. The three-compartment cell operated at more than 80% current efficiency over most of the conversion range, with a voltage drop of 2·7 V per repeating unit at 400 Am−2 and 25° C.
