Method Of Preparing Halogenated Silahydrocarbylenes |
摘要 |
A method comprises separate and consecutive steps (i) and (ii). Step (i) includes contacting a copper catalyst with hydrogen gas and a halogenated silane monomer at a temperature of 500° C. to 1400° C. to form a silicon-containing copper catalyst comprising at least 0.1% (w/w) of silicon. Step (ii) includes contacting the silicon-containing copper catalyst with an organohalide at a temperature of 100° C. to 600° C. to form a reaction product. The organohalide has formula HaCbXc, where X is a halogen atom, subscript a is an integer of 0 or more, subscript b is an integer of 1 or more, and subscript c is an integer of 2 or more. The method produces a reaction product. The reaction product includes a halogenated silahydrocarbylene. |
