Abstract
An improvement in the production of .beta.-chloroethyltrichlorosilane by reacting hydrogen chloride with vinyl trichlorosilane in the presence of aluminum chloride at elevated pressure at temperatures between 0.degree. and 90.degree. C is disclosed, which comprises using the aluminium chloride which remains in the reaction vessel after separating off the .beta.-chloroethyltrichlorosilane, and which still contains .beta.-chloroethyltrichlorosilane, directly for the next reaction.

In a process for the production of .beta.-chloroethyltrichlorosilane by reacting hydrogen chloride with vinyl trichlorosilane in the presence of aluminium chloride at elevated pressure at temperature between 0.degree. and 90.degree. C, the improvement which comprises using the aluminium chloride which remains in the reaction vessel after separating off the .beta.-chloroethyltrichlorosilane by distillation, and which still contains .beta.-chloroethyltrichlorosilane, directly in the next reaction, provided that .beta.-chloroethyltrichlorosilane is distilled off after each reaction in such an amount that the residue constitutes a still stirrable broth.
