A process for producing an aziridine compound represented by the following general formula (II) wherein R represents hydrogen, or a methyl or ethyl group, which comprises intramolecularly dehydrating an alkanolamine represented by the following formula (I) wherein R is as defined, X is OH or NH2, and Y is NH2 when X is OH, and OH when X is NH2, in the presence of a catalyst in the vapor phase in a reaction step (A) to form a reaction product containing the aziridine compound, and subjecting the reaction product to any one of the following procedures (1) to (3), (1) sending the reaction product to a recovery step (B) and recovering the aziridine compound in the presence of an amine compound, (2) sending the reaction product to a distillation step (C) and distilling the aziridine compound in the presence of an amine compound, and (3) sending the reaction product to the recovery step (B), recovering the aziridine compound in the presence of an amine compound, sending the recovered aziridine compound to the distillation step (C) and distilling it in the presence of an amine compound. |
