Vinyl-containing organosilicon compounds as the Speier catalyst additives

Abstract

The effect of a number of vinyl-containing organosilicon compounds used as the Speier catalyst additives upon the activity of the resulting catalyst was studied. The most active additives turned out to be hexavinyldisiloxane, tetramethyldivinyldisiloxane, and dimethyldivinylsilane. It was found also that the activity of the Speier catalyst additives depends on the method of the catalyst preparation
