| titleOfInvention | Method of producing ethylenediamines |
| abstract | A method of producing ethylenediamines reprensented by the general formula nH₂NCH₂ nHNH₂ (I) n nwherein R represents a hydrogen atom, or a nmethyl or ethyl group, nWhich comprises reacting an aziridine compound of the ngeneral formula n nwherein R is as defined, nwith ammonia in the gaseous phase in the presence of a nsolid acid catalyst. In another aspect, a method of nproducing ethylenediamines of the general formula (I), nwhich comprises reacting a reaction product containing an nazirieine compound of the general formula (II), obtained nby the gaseous phase intramolecular dehydration reaction nof an alkanolamine represented by the general formula nnH₂- nH-R (III) n nwherein X represents the OH group or the NH₂ ngroup, Y represents the NH₂ group when X is the nOH group and the OH group when X is the NH₂ ngroup, and R is as defined, nin the presence of a catalyst A, with ammonia in the ngaseous phase in the presence of a solid acid catalyst n(catalyst B). |
