| Abstract: | A multi-component catalyst for ethylene oxychlorination to vinyl chloride was developed by introduction of a second component （K） and a third component （rare earth）. The reaction condition ethylene oxychlorlnation to vinyl chloride was as follows： reaction temperature 220 ℃, reaction pressure 0.3 MPa, n（ C2H4 ）： n（HCl） ： n（ O2 ） = 1.04： 2： 0.57. HCl conversion of over 99.5% and selectivity to ethylene dichloride of over 99.3% were obtained under above condition over the catalyst with optimal K content of 0.6% -0.9% （mass fraction） and optimal Ce or La content of 0.4% -0.6%. |
