    摘要: A process for preparing trifluorochloroethylene including: in a multi-tubular reactor, hydrogenation reacting 1,1,2-trifluoro-1,2,2-trichloroethane directly with a catalyst potassium zinc trihydride to obtain trifluorochloroethylene, wherein the catalytic reaction is performed at a temperature of 250-350° C. and a pressure of 0.7-1.0 MPa for 10-20 seconds. The conventional process in which zinc powder is used for dechlorination or hydrogen is used for dechlorination through hydrogenation with the action of a noble metal catalyst is avoided in the process disclosed herein. The present process substantially reduces the production cost of trifluorochloroethylene, and substantially increases the product yield, which can be up to 99% or more.

    摘要: The present invention relates to a process for manufacturing neohexene, comprising contacting isobutene with a supported catalyst comprising a tungsten compound chosen from tungsten hydrides, organometallic tungsten compounds and organometallic tungsten hydrides, and a support comprising an oxide of aluminum, so as to form a reaction mixture comprising neohexene, and preferably separating neohexene from the reaction mixture, so as to isolate it. The contacting leads to the direct production of neohexene, in particular in a single (reaction) stage and with a high molar selectivity for neohexene. The contacting can be performed at a temperature of 50 to 600 ° C., under a total absolute pressure of 0.01 to 100 MPa.
