4 mg of platinum in the form of hexachloroplatinic acid are added to 88.5 g (0.66 mol) of allyl phenyl ether under a nitrogen atmosphere and the mixture is heated to 80° C. 125 g of dimethylchlorosilane are metered into the mixture over a period of 2 hours, the liquid-phase temperature falling to below 50° C. The mixture is stirred for a further 6 hours under gentle reflux. Fractional distillation gives a total of 112 g of 3-phenoxypropyldimethylchlorosilane. The product has an acid number of 248 (theoretically 244).
