一、前言由硅和氯甲烷在催化剂存住下直接合成甲基氯硅烷(罗乔合成法),是有机硅工业的基础,因此,选择廉价高效的催化剂是非常重要的。铜是氯甲烷与硅反应的经典的催化剂。目前,我国主要采用氯化亚铜为催化剂,铜粉催化剂尚处于研究之中。欧美各国早已应用铜粉催化剂,例如美国GE公司1955年就以铜粉为催化剂,联邦德国Wacker公司1974年也改用铜粉为催化剂,苏联的有机硅工厂虽多采用硅铜合金,但越来越多的人主张改用铜粉催化剂。究其根源,这是因为:铜粉催化剂成本 I. INTRODUCTION Direct synthesis of methylchlorosilane (Robocher synthesis) from silicon and methyl chloride in the presence of a catalyst is the basis of the silicone industry, so it is important to choose a cheap and efficient catalyst. Copper is the classic catalyst for the reaction of methyl chloride with silicon. At present, China mainly uses cuprous chloride as a catalyst, copper powder catalyst is still under study. Copper oxide catalysts have long been used in many countries in Europe and the United States. For example, GE in the United States used copper powder as a catalyst in 1955, and Wacker in the Federal Republic of Germany also used copper powder as a catalyst in 1974. Although the Soviet Union’s silicon plant uses silicon-copper alloy more, The more people advocate the switch to copper powder catalyst. The root causes, this is because: copper powder catalyst costs
