Silicones - Essential Chemical Industry

Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper alyst (often copper itself but other copper-containing materials can be used, for example, brass or copper(II) chloride) a volatile mixture of chlorosilanes
