<P>PROBLEM TO BE SOLVED: To provide a method for producing an alkylene oxide adduct such as a glycerol/alkylene oxide copolymer or the like by reacting an organic compound having an active hydrogen atom such as glycerol or the like with an alkylene oxide such as propylene oxide, ethylene oxide or the like. <P>SOLUTION: In the method for producing an alkylene oxide adduct by reacting an organic compound having at least one active hydrogen atom with an alkylene oxide, the method is characterized in that the reaction is carried out by dispersing a gas phase of the reaction system as finely divided air bubbles into a liquid phase in a reactor. There are an embodiment that the gas phase of the reaction system extracted from the reactor is supplied in the form of finely divided air bubbles to the liquid phase in the reactor, additionally an embodiment in which the gas phase of the reaction system extracted from the reactor is made in the form of finely divided air bubbles produced by mechanically treating the gas phase, and the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
