通过乙炔氢氯化反应（AHR）生产氯乙烯单体（VCM）消耗大量剧毒汞催化剂。迫切需要一种廉价、无毒、有效的替代品。本文设计了一种具有优良催化性能的AHR用AuI催化剂。设计的0.1AuI（wt%）/AC 2催化剂的催化效率与商业汞催化剂相当，适用于氯乙烯的工业生产。理论计算确定了AuI活化C2 H2的机理，并强调了AuI的高稳定性。
Production of vinyl chloride monomer (VCM) via acetylene hydrochlorination reaction (AHR) is consuming huge amount of mercury catalyst that is highly toxic. A cheap, nontoxic, and effective alternate is urgently required. Here, we designed an AuI catalyst for AHR with the excellent catalytic performance. The designed 0.1AuI(wt%)/AC2 catalyst shows the comparable catalytic efficiency to the commercial mercury catalyst, which is applicable for industrial production of VCM. Theoretical calculations determine the activation mechanism of C2H2by AuI, and highlight the high stability of AuI.
