Alkenyl chlorosilanes such as vinylchlorosilane and allylchlorosilane have been widely employed as coupling agents, which when incorporated at modest levels, enhance many of the physical properties of polymer composites, in plastic industry. As a conventional method, synthesizing alkenylchlorosilanes can be prepared by reaction of metallic silicon with alkenylchloride, HCl in the presence of catalyst or reactions of a hydrosilylation with acetylene or butadiene derivat-ives of the presence of transition metal. We have studied synthesis of alkenylchlorosilane by simple thermaldehydro-chlorinative Si-C coupling reaction of hydrosilane with alkenyl chloride at temperature 400 to 650℃ with out a catalyst. The yields of akenylchlorosilane depend on the reaction temperature, feeding rate, mixing ratio of reactants and reactor type. |
