Method of producing aziridine compounds.

摘要

A method of producing an aziridine compound of the general formula <CHEM> wherein R represents a hydrogen atom or a methyl or ethyl group, which comprises subjecting an alkanolamine represented by the following formula @H2- @H-R (II) wherein R is as defined, X represents the OH group or the NH2 group, and Y represents the NH2 group when X is the OH group, and the OH group when X is the NH2 group, to intramolecular dehydration reaction in the gaseous phase in the presence of a catalyst; wherein the catalyst contains acid sites having an acid-base strength (Ho) of from +4.0 to +7.0 and base sites having an acid-base strength of from +7.0 to +9.3.
