ABSTRACT:
A method of producing ethylenediamines represented by the general formula ##STR1## wherein R represents a hydrogen atom, or a methyl or ethyl group, which comprises reacting an aziridine compound of the general formula ##STR2## wherein R is as defined, with ammonia in the gaseous phase in the presence of a solid acid catalyst. In another aspect, a method of producing ethylenediamines f the general formula (I), which comprises reacting a reaction product containing an aziridine compound of the general formula (II), obtained by the gaseous phase intramolecular dehydration reaction of an alkanolamine represented by the general formula ##STR3## wherein X represents the OH group or the NH.sub.2 group, Y represents the NH.sub.2 group when X is the OH group and the OH group when X is the NH.sub.2 group, and R is as defined, in the presence of a catalyst A, with ammonia in the gaseous phase in the presence of a solid acid catalyst (catalyst B).
