Filed: 1986-06-27
Abstract: PURPOSE:To moderate reaction condition of a hydrogenation reactor and improve the yield of dichlorosilane, by reacting silicon tetrachloride with metallic silicon at a specific temperature and simultaneously reducing the resultant reaction product with hydrogen gas. CONSTITUTION:Metallic silicon and silicon tetrachloride are respectively fed to a reaction column 1 and reacted at a temperature within the range of 1,100-1,300 deg.C. The resultant reaction product is then introduced into a hydrogenation column 5, quenched with hydrogen gas (from a hydrogen circulator 8) and cooled to a temperature within the range of 400-700 deg.C and simultaneously reduced with the hydrogen to form a mixed gas of dichlorosilane, trichlorosilane, silicon tetrachloride and hydrogen. The resultant mixed gas is then cooled (in a cooler 6) and separated into the hydrogen gas and liquefied dichlorosilane, trichlorosilane and silicon tetrachloride in a separator 7. The hydrogen gas, together with supplied hydrogen gas, is circulated through the hydrogen circulator 8 and fed into the hydrogenation column 5. On the other hand, the liquefied substances, e.g. silane, etc., are separated into the silicon tetrachloride, dichlorosilane and trichlorosilane in a distillation step and the silicon tetrachloride is circulated and fed to the reaction column 1.
