实验过程

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 the course of two hours, the bottom temperature falling to below 50° C. The mixture is stirred for a further six hours under gentle reflux. After fractional distillation, a total of 112 g of 3-phenoxypropyldimethylchlorosilane are obtained. The product has an acid number of 248 (theoretically 244).
