摘要
Rochow反应是一种多相催化反应,用于直接合成有机硅产品的原料——甲基氯硅烷,因其较低的生产成本和较为简单的生产工艺,至今仍是生产甲基氯硅烷的主流工艺。铜基催化剂作为Rochow反应的核心催化剂,改善其催化性能成了提升该工艺的重心。由于在实际的生产过程中产生的副产物多且杂,对真实的反应路径和机理研究仍不明确,因此探究了Rochow反应的基本原理,综述了铜基催化剂催化该反应的研究现状以及发展趋势。重点阐述了改性铜基催化剂对催化性能的影响及催化机理,希望对高效铜基催化剂的设计提供指导作用,从而促进有机硅工业的发展。
Rochow reaction is a multiphase catalytic reaction for directly synthesizing the raw material(methylchlorosilanes)of silicone products.It is still the mainstream process for the production of methylchlorosilanes,because of its lower production cost and relatively simple production process.Copper-based catalysts,as the core catalyst,are used in Rochow reaction,then improving the performance of copper-based catalysts has become the center of this technological development.However,in the actual production process,due to the various and miscellaneous by-products,the real reaction path is difficult to track and the reaction mechanism is still unclear.In this review,the basic principle of Rochow reaction was discussed,and the research progress and development trend of Rochow reaction catalyzed by copper-based catalyst were summarized.In addition,the influences of modified copper-based catalyst on the catalytic performance and the catalytic mechanism were emphatically described,hoping to provide a guidance for the design of high efficiency copper-based catalyst,so as to promote the development of silicone industry.
