摘　　要：乙炔法制备聚氯乙烯过程中的“汞问题”一直备受关注,无汞金属基催化剂的研发是此领域中的研究热点.本文通过活性组分的促进(金属和非金属掺杂、配体及离子液体调控)、载体的优化(碳基和硅铝氧基载体)及材料制备方法的改良三个方面,综述了近几年用于乙炔氢氯化反应的无汞金属催化剂改性的研究进展,并对其发展前景进行了展望.The development of mercury-free metal catalysts has been a hot topic for sustainable polyvinyl chloride(PVC)production currently,but the“mercury problems”for acetylene hydrochlorination has been a major concern in China.In this paper,the research progress of mercury-free metal catalyst modification for acetylene hydrochlorination in recent years has been reviewed through the promotion of active sties(metal and non-metal doping,ligand and ionic liquid regulation),the optimization of support(carbon-based and silicon aluminoxy supports)and the improvement of material preparation methods,and the development trend was discussed.
