PURPOSE:To produce a polychlorosilane in high yield, preventing the corrosion of the reaction apparatus, by reacting an Si alloy with chlorine diluted with an inert gas. CONSTITUTION:Chlorine gas diluted to 0.1-3.0mol% with in inert gas such as N2, Ar, etc. is introduced into an apparatus made of stainless steel and filled with an Si alloy, and is reacted with the alloy at 150-300 deg.C under normal pressure - 10atm.
