Abstract
Disclosed is a method for producing chloropolysilane by which the yield of a fluid reaction to produce the chloropolysilane is improved while blockage in a reactor caused by attachment of higher-order silicon chloride as a by-product is prevented. In producing the chloropolysilane by reacting fluidized silicon particles or silicon alloy particles with a chlorine gas, an outlet filter is provided, upstream from a product outlet that releases a reaction product, above the area in which the silicon particles or silicon alloy particles are fluidized inside a reaction tank. The outlet filter prevents fine particles blown up by fluidization from flowing out of the reaction tank through the product outlet. A temperature of the outlet filter is set in a range of 210 to 350° C.
