METHOD FOR PREPARING CHLOROHYDRINS COMPOSITION AND METHOD FOR PREPARING EPICHLOROHYDRIN USING CHLOROHYDRINS COMPOSITION PREPARED THEREBY |
摘要 |
<p>A method of preparing a chlorohydrin composition and a method of preparing epichlorohydrin by using a chlorohydrin composition prepared by using the method are provided. The method of preparing a chlorohydrin composition in which a polyhydroxy aliphatic hydrocarbon is reacted with a chlorination agent in the presence of a catalyst includes performing at least one combination of a series of unit operations comprising a first reaction step, a water removal step, and a second reaction step in this stated order, wherein the method further includes mixing a chlorohydrin concentrate obtained by purifying the reaction mixture discharged from the final reaction step from among the plurality of reaction steps and a water-rich layer discharged from the water-removal step. The method of preparing epichlorohydrin includes contacting the chlorohydrin composition prepared by using the method of preparing a chlorohydrin composition with an alkaline agent</p> |
