Abstract: In a method for acetylene hydrochlorination to vinyl chloride catalyzed by ultra-low content aurum-based material, a nitrogen-modified activated carbon support is obtained by using 1,10-phenanthroline as a modifier. A trace amount of aurum is used as a main active component and an organic solvent with a low polarity and a low boiling point, isopropanol, is used as a solvent. An ultra-low content of aurum-based catalyst with the aurum loading amount of 0.01 wt % using the above nitrogen-modified activated carbon as a support is prepared by improving the synthesis procedure, and the efficiency of the catalyst is significantly improved. The catalyst has high activity and vinyl chloride selectivity for acetylene hydrochlorination to vinyl chloride, which is low cost, no mercury pollution, simple in preparation process and expansibility, and has great industrial application value.
