Vinyl chloride monomer (VCM) is a major chemical intermediate for the manufacture of polyvinyl chloride (PVC), which is the third most important polymer in use today. Hydrochlorination of acetylene is a major route for the production of vinyl chloride, since production of the monomer is based in regions of the world where coal is abundant. Until now, mercuric chloride supported on carbon is used as the catalyst in the commercial process, and this exhibits severe problems associated with catalyst lifetime and mercury loss. It has been known for over 30 years that gold is a superior catalyst, but it is only now that it is being commercialized. In this Perspective we discuss the use and disadvantages of the mercury catalyst and the advent of the gold catalysts for this important reaction. The nature of the active site and the possible reaction mechanism are discussed. Recent advances in the design and preparation of active gold catalysts containing ultralow levels of gold are described. In the final part, a view to the future of this chemistry will be discussed as well as the possible avenues for the commercial potential of gold catalysis.

乙炔氢氯化用金催化剂的发现、开发和商业化

氯乙烯单体 (VCM) 是制造聚氯乙烯 (PVC) 的主要化学中间体，它是当今使用的第三大最重要的聚合物。乙炔的氢氯化是生产氯乙烯的主要途径，因为该单体的生产基地位于世界上煤炭丰富的地区。迄今为止，碳载氯化汞被用作商业过程中的催化剂，这表现出与催化剂寿命和汞损失相关的严重问题。30 多年来，人们都知道黄金是一种优良的催化剂，但直到现在它才被商业化。在这个视角中，我们讨论了汞催化剂的使用和缺点以及金催化剂在这一重要反应中的出现。讨论了活性位点的性质和可能的反应机理。描述了含有超低水平金的活性金催化剂的设计和制备的最新进展。在最后一部分，将讨论对这种化学未来的看法以及金催化商业潜力的可能途径。
