Method for preparing oxirane-containing organosilicon compositions

A method for preparing an organosilicon composition from an olefin and a silicon hydride with a hydrosilation catalyst PtL2X2, in an amount less than 1 ppm based on the weight of the product composition, is disclosed. The method is particularly useful in lowering the cost, coloration, and stability...

Zusammenfassung:	A method for preparing an organosilicon composition from an olefin and a silicon hydride with a hydrosilation catalyst PtL2X2, in an amount less than 1 ppm based on the weight of the product composition, is disclosed. The method is particularly useful in lowering the cost, coloration, and stability of the product, particularly when an oxirane-containing olefin is used in the hydrosilation. In this method no inhibitor is needed to prevent the undesired polymerization of oxiranes in the reaction, and no purification of the product is required after removal of volatile components, including solvent.
