380 g of diphenyldichlorosilane, 22.5 g of anhydrous aluminium chloride and 2.3 g of anhydrous alumina (specific surface area : 0.1 m2 /g) are placed in a flask. 477 g of trichlorosilane are run in over the course of 6 hours 50 minutes, whilst keeping the reaction mixture at 70°C and distilling the dichlorosilane. A fraction weighing 76 g, containing 74% of dichlorosilane, is obtained. 370 g of phenyltrichlorosilane are obtained on distilling the mixture remaining in the flask.
