|Section2= |Section3= |Section4= }} Chlorosilanes are a group of reactive, chlorine-containing chemical compounds, related to silane and used in many chemical processes. Each such chemical has at least one silicon-chlorine bond. ==Synthesis== They are prepared by the Müller-Rochow process, which involves treating silicon with hydrogen chloride at elevated temperatures in the presence of a copper catalyst. The idealized equation is :2 Si + 6 HCl → 2 HSiCl3 + 2 H2, Trichlorosilane (HSiCl3) is the main product; dichlorosilane (H2SiCl2) and silicon tetrachloride (SiCl4) are obtained as byproducts. The process was independently discovered by Eugene G. Rochow and Richard Müller in 1940.
