Title:
METHOD FOR MANUFACTURING 1,2-DICHLOROETHANE
Document Type and Number:
Japanese Patent JP2014125438
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel method for manufacturing 1,2-dichloroethane capable of manufacturing, from ethylene in a high yield, 1,2-dichloroethane useful as a raw ingredient of a vinyl chloride monomer.SOLUTION: The provided method for manufacturing 1,2-dichloroethane uses, on an occasion for manufacturing 1,2-dichloroethane by inducing, in the presence of an oxychlorination catalyst, an oxychlorinating reaction of ethylene, hydrogen chloride, and air, a serial oxychlorination reaction process equipped with at least two fixed bed circulation-type catalytic reaction columns and executes an oxychlorinating reaction by filling, into the rearmost downstream-side fixed bed circulation-type catalytic reaction column of the serial oxychlorination catalytic reaction process, a hollow cylindrical oxychlorination catalyst (1) including, within a carrier, at least copper chloride and one or more types of metal cation halides having coordinated water exchanging reaction velocities of below 1×10sat 298K.
