Method for producing hydrogenated polysilane compound

Abstract

The purpose of the present invention is to produce a high quality hydrogenated polysilane compound by reducing process troubles using the halosilane raw material and the reducing agent. A method for producing a hydrogenated polysilane compound (CX) of the present invention contains a reducing step (P1) in which a halosilane raw material (C0) selected from a polyhalosilane compound (C1) comprising a Si—Si bond and a Si—X bond (X represents a halogen atom) in the same molecule, a salt of the polyhalosilane compound (C2), and a complex of the polyhalosilane compound (C3) is contacted with a reducing agent (R2) to reduce the halosilane raw material (C0), and a removing step in which a reaction solution of the reducing step (P1) is subjected to one or more steps selected from the following (T1) to (T4) to remove the reducing agent (R2) and/or a resulting material of the reducing agent (R2) contained in the reaction solution. (T1) separating step of a solid and a liquid (T2) separating step of one liquid and another comprising a reaction solution, a concentrated solution of the reaction solution, or a washing solution of the reaction solution or the concentrated solution of the reaction solution (T3) contacting step with an acid aqueous solution (T4) distilling step of the hydrogenated polysilane compound (CX)
