Document Type and Number:
WIPO Patent Application WO/2012/002649
Kind Code:
A2
Abstract:
Disclosed are a method for preparing chlorohydrins and a method for preparing epichlorohydrin using chlorohydrins prepared thereby. The disclosed method for preparing chlorohydrins reacts polyhydroxy aliphatic hydrocarbon with a chlorination agent in the presence of a catalyst, and comprises at least one combination of a series of unit operations including a first reaction step, a water removal step, and a second reaction step, in the respective order, wherein the water removal step is implemented by performing a distillation operation on a reaction mixture having a specific content ratio by using the difference in boiling points between the constituents of the reaction mixture. The disclosed method for preparing epichlorohydrin includes a step for reacting the chlorohydrins, which was prepared using the method for preparing chlorohydrins, with an alkaline chemical.
