ABSTRACT:
A method of producing alkylene oxide adduct comprises reacting an organic compound having one or more active hydrogen (for example, higher alcohol, amine, etc.) with alkylene oxide in the presence of an Al.Mg composite oxide catalyst. The catalyst can be obtained by calcining and activating aluminum magnesium hydroxide shown by nMgO.Al.sub.2 O.sub.3.mH.sub.2 O. In this method, a highly active reaction can be performed, and alkylene oxide adduct having very narrow alkylene oxide adduct molar distribution can be obtained. Since the load in a catalyst separating step is reduced, the catalyst can be efficiently separated. Therefore, the alkylene oxide adduct can be produced at low cost. In addition, the reaction can be performed at high speed, and the reaction time can be reduced.
