Abstract
A method for regeneration of catalyst which comprises phosphorus and alkali metal element and/or alkaline earth metal element and was deteriorated by use to produce aziridine compound represented by the general formula ##STR1## wherein R is hydrogen, a methyl group or an ethyl group, by a catalytic vapor-phase intramolecular dehydration reaction of alkanolamine represented by the general formula ##STR2## wherein R is as defined in the formula (II), X is OH or NH.sub.2, and Y is either NH.sub.2 when X is OH or OH when X is NH.sub.2, characterized in that the deteriorated catalyst is contacted with gaseous volatile phosphorus compound.
