PRODUCTION OF AZIRIDINE COMPOUND

Japanese Patent JPH02223550

A

PURPOSE: To suppress production of a by-product such as carbonyl compound and obtain the title compound useful as a raw material for medicine, agricultural chemical, etc., in high selectivity and yield by subjecting an alkanolamine to intramolecular dehydration reaction in vapor phase using a specific catalyst.

CONSTITUTION: An alkanolamine expressed by formula I (X is OH or NH2; Y is NH2 when X is OH; Y is OH when X is NH2; R is R, CH3 or C2H5) is subjected to vapor phase intramolecular dehydration reaction in the presence of a catalyst obtained by combining an acidic oxide such as silicon oxide with an oxide of alkali(earth) metal such as Ba(OH)2, having an acid point having function (Ho) of acid base strength of 4.0-7.0 and basic point having function (Ho) of acid base strength of 7.0-9.3 and having a catalyst composition expressed by the formula Si1Ba0.3 at 10-500°C under ordinary pressure, reduced pressure or pressure at space velocity of 100-30000hr-1 to provide the aimed compound expressed by formula II such as ethylene imine useful as a raw material for amine based polymer which is a fiber treating agent.
