乙炔氢氯化制备氯乙烯的非汞催化技术研究

Study of the catalytic hydrochlorination of acetylene with nonmercuric catalytic systems

介绍了非汞催化乙炔氢氯化制备氯乙烯的研究状况、催化剂性能、反应技术等,并指出了今后非汞催化乙炔氢氯化制备氯乙烯的研究重点和研究方向。

The hydrochlorination of acetylene is an important industrial process for the preparation of vinyl chloride. Catalysts are usually based on mercuric chloride supported on activation carbon. The high toxicity forces out the search for nonmercuric catalytic systems. The capabilities, the reactor technologies and some crucial problems of these catalysts systems have been discussed.
