380 g of diphenyldichlorosilane (in which 0.7 g of hydrogen chloride has been dissolved beforehand by bubbling in the gas) and 22.5 g of aluminium chloride are introduced into the flask. 80 cm3 of trichlorosilane are run in, the mixture is heated to 70°C and then 477 g of trichlorosilane are introduced gradually over the course of 7 hours 30 minutes, whilst distilling the resulting dichlorosilane as it is formed. A distillate weighing 79 g, containing 60.8 g of dichlorosilane, is obtained. 356 g of phenyltrichlorosilane are obtained on distilling the mixture remaining in the flask.
