<p>PURPOSE:To replenish phosphorus to a catalyst and carry out regeneration easily and quickly by bringing a deteriorated catalyst for manufacturing an aziridine compound into contact with a gaseous volatile phosphide. CONSTITUTION:An aziridine compound in the general formula II (R = formula I) is manufactured by dehydration reaction in contact gas phase molecule of alkano amine represented by the general formula I (R is H, CH3 or the like, when X is OH or NH2, Y is NH2 or OH). At that time, a catalyst used and deteriorated phosphorus and alkali metal element and/or alkaline earth metal element are brought into contact with gaseous volatile phosphorus compound such as ester phosphate group or ester phosphite group. Thus, phosphorus can be replenished to the catalyst, and regeneration of catalyst can be carried out easily and quickly.</p> |
