METHOD FOR PREPARING CHLOROHYDRINS AND METHOD FOR PREPARING EPICHLOROHYDRIN USING CHLOROHYDRINS PREPARED THEREBY |
摘要 |
<p>A method of preparing chlorohydrins and a method of preparing epichlorohydrin using chlorohydrins prepared by using the same method are provided. The method is to prepare chlorohydrins by reacting polyhydroxy aliphatic hydrocarbon with a chlorination agent in the presence of a catalyst, and the method includes at least one combination of a series of unit operations including the following steps in the following stated order: a first reaction step; a water removal step; and a second reaction step, wherein the water removing step is performed by distillation operation based on a boiling point difference between constituents of a reaction mixture. The method of preparing epichlorohydrin includes reacting chlorohydrins prepared by using the method of preparing chlorohydrins with an alkaline agent.</p> |
