Summary:PROBLEM TO BE SOLVED: To provide a manufacturing method of epichlorohydrin, by dechlorohydrogenation of a dichlorohydrin mainly composed of 1,3-dichloro-2-propanol, which is excellent in the light of yield, waste water load, and energy used in its manufacturing. SOLUTION: In a process in which epichlorohydrin is generated by dechlorohydrogenation of a dichlorohydrin mainly composed of 1,3-dichloro-2-propanol, it was found that the reaction liquid after dechlorohydrogenation of dichlorohydrin can be separated by the difference of specific gravities of an oil layer and a water layer, and that the property of liquid separation can be controlled by limiting the molar ratio of 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol of the dichlorohydrin to be dechlorohydrogenated within 87:13-100:0. Optionally, the resultant oil layer and the water layer are treated intermediately. COPYRIGHT: (C)2010,JPO&INPIT
