摘要
A method of preparing chlorohydrins and a method of preparing epichlorohydrin by using chlorohydrins prepared using the method are provided. The method of preparing chlorohydrins by reacting polyhydroxy aliphatic hydrocarbon with a chlorination agent in the presence of a catalyst includes 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 that respective order, and after mixing at least a portion of a reaction mixture discharged from at least one reaction steps from among the plurality of reaction steps with an additional chlorination agent, recirculating the resulting mixture to the reaction step from which the reaction mixture was discharged. The method of preparing epichlorohydrin includes a step of reacting chlorohydrins prepared using the method of preparing chlorohydrins, with an alkaline agent.
