Process for synthesizing alkenyl disiloxane

Abstract

Described herein are methods for making alkenyl disiloxanes, comprising combining an alkenyl halosilane with a bis-hydrido terminated alkyl disiloxane and adding the mixture to water, an acidic aqueous solution, or a basic aqueous solution. The ratio of the alkenyl halosilane to the bis-hydrido terminated alkyl disiloxane is about 1:10 to about 10:1. The alkenyl halosilane and bis-hydrido terminated alkyl disiloxane are mixed at about 20° C. to about 45° C. In an example, no organic solvent is present. The reaction product is separated and washed with saturated NaHCO3 solution (e.g., sodium bicarbonate).
