Abstract

This invention relates to a process for producing ethylene diamine in high selectivity and high conversion by reacting monoethanolamine with ammonia in the presence of a catalyst. The catalyst which permits the production of ethylenediamine in high selectivity and high conversion is a hydrogen mordenite catalyst that has been treated in such a manner as to raise the silicon to aluminum ratio of the mordenite, such treatment, then being referred to as partial dealumination.
