<p>A novel process for producing an N-substituted aziridine compound by the vapor-phase catalytic dehydration of an N-substituted alkanolamine represented by reaction formula (I), wherein R?1, R2 R3 and R4¿ represent each independently hydrogen or C¿1? to C4 alkyl, and X represents C1 to C4 alkyl, cyclohexyl, phenyl, benzyl, C1 to C4 hydroxyalkyl or C1 to C4 aminoalkyl. An N-substituted aziridine compound can be produced at a high yield by conducting the reaction preferably under the conditions of a reaction pressure of 5 to 250 mmHg, a reaction temperature of 300 to 450 °C, and a space velocity of 50 to 500 hr?-1¿ (STP) in the presence of a catalyst based on silicon or phosphorus.</p> |
