Abstract
Boron, aluminum and gallium C.sub.1 -C.sub.18 perfluoroalkanesulfonates (CF.sub.3 (CF.sub.2).sub.n SO.sub.3).sub.3 M (M=B, A1, Ga; n=0-17) as well as perfluororesin sulfonates such as Nafionates are new, highly effective Friedel-Crafts catalysts. In contrast to volatile aluminum and boron trihalides, the Group III-B perfluoroalkanesulfonates are generally of low or no volatility and, except for boron triflate and some of its homologs, only sparingly soluble incommon organic solvents. This allows their use as solid or supported Friedel-Crafts catalysts of wide utility and scope in continuous heterogenous catalytic processes. At the same time, boron triflate and related lower perfluoroalkanesulfonates are particularly efficient soluble catalysts in solution reactions.
Claims10
A process for effecting hydrocarbon reforming which comprises contacting a C.sub.4 to C.sub.30 hydrocarbon with a Friedel-Crafts catalyst comprising a boron, aluminum, or gallium perfluoroalkane sulfonate at suitable reforming temperature and pressure conditions and for a time sufficient to effect said hydrocarbon reforming.
A process for effecting hydrocarbon reforming which comprises contacting a C.sub.4 to C.sub.30 hydrocarbon with a Friedel-Crafts catalyst comprising a boron, aluminum or gallium salt of one of a perfluorinated polymeric resinsulfonic acid, a polytrifluoroethylene-sulfonic acid, or a tetrafluoroethylene-trifluoroethylene-sulfonic acid copolymer at suitable reforming temperature and pressure conditions and for a time sufficient to effect said hydrocarbon reforming.
An alkylation process which comprises passing an alkylatable C.sub.4 to C.sub.30 hydrocarbon and an alkylating agent over a Friedel-Crafts catalyst comprising a boron, aluminum or gallium perfluoroalkane sulfonate to effect a continuous heterogenous flow alkylation of said hydrocarbon at a temperature between 0.degree. and 200.degree. C., a pressure between atmospheric and 50 atmospheres and for a time sufficient to effect said alkylation.
An isomerization process which comprises passing C.sub.4 to C.sub.30 hydrocarbon over a Friedel-Crafts catalyst comprising a boron, aluminum, or gallium perfluoroalkane sulfonate to effect a continuous heterogenous flow isomerization of said hydrocarbon at a temperature between 0.degree. and 300.degree. C., a pressure between atmospheric and 50 atmospheres and for a time sufficient to effect said isomerization.
