PROCESSES FOR SYNTHESIZING UNSYMMETRICAL DISILOXANES
Described herein are methods for making alkenyl disiloxanes, comprising combining an alkenyl halosilane with an alkyl halosilane and adding the mixture to water, an acidic aqueous solution, or a basic aqueous solution. The ratio of the alkenyl halosilane to the alkyl halosilane is about 10:1 to about 1:10. The alkenyl halosilane and the alkyl halosilane are mixed at about 20 °C to about 45 °C. The reaction product is separated and washed with saturated alkali carbonate solution.
