摘要
Rochow-Müller反应是一种直接合成甲基氯硅烷的方法。由于其原料易得,产物收率高,工艺较易实现,成为有机硅工业单体生产的主流工艺。到目前为止,铜基催化剂仍为Rochow-Müller反应的核心催化剂,催化性能的改善对该工艺的提升具有重大意义。在探索高效催化剂和理解其机理方面已取得相关进展,但由于副产物多,复杂性高,对该反应真实反应路径的追踪仍然较为困难。对Rochow-Müller反应的热力学过程、铜基催化剂及助催化剂的应用、反应机制及动力学过程和工艺条件的影响进行综述讨论。希望这项工作能够准确地反应Rochow-Müller反应催化工艺的最新进展,并可以促进有机硅工业的可持续性发展。
The Rochow-Müller process is for the direct synthesis of methylchlorosilane.Because of its easy availability of raw materials,high product yield,and easier process implementation,it has become the mainstream process in the organosilicon industry.So far,the copper-based catalyst is still the core catalyst of the Rochow-Müller reaction,and the improvement of catalytic performance is of great significance to the improvement of the process.Although significant progress has been made in exploring high-efficiency catalysts and understanding its mechanism,it is still difficult to track the true reaction path due to many by-products and high complexity.This paper provides a comprehensive overview on the thermodynamic process of the Rochow-Müller reaction,the application of copper-based catalysts and co-catalysts,the reaction mechanism,kinetics,and the influence of process conditions.We hope that this work could accurately reflect the latest progress in the catalytic process of the Rochow-Müller reaction and promote the sustainable development of the silicone industry.
