Method of preparing vinyl chloride monomer using ethylene dichloride

摘要

This invention relates to a method for the addition of co-catalyst in the production of vinyl chloride monomer pyrolysis reaction of ethylene dichloride characterized in that the co-catalyst as the (P) 5 comprises a compound or a boron (B) 3 compound, when controlling the outlet temperature of the reactor was 490 ~ 500 , the conversion range 50% to 70%, ethylene dichloride from the conversion of a vinyl chloride monomer (conversion) is increased in the range of 5 to 20%, by-products generated during the thermal decomposition reaction is about the production of vinyl chloride monomer, characterized in that the decrease in the range of 5-40% such, the yield of the co-catalyst by-product is produced can be act as a co-catalyst in the EDC reaction and at the same time act as coke inhibitors is suppressed while vinyl chloride monomer according to the present invention has an effect that can increase.
