A process is described for paraffin isomerization under strong acid conditions in which in aminoalkyladamantane is used to substantially increase the reaction rate of the isomerization.
摘要:
A catalyst comprising (a) a carrier mainly consisting of alumina, (b) an aromatic compound substituted with at least 2 hydroxy, oxo or hydrocarbyloxy groups and (c) halogen, and optionally, but preferably, containing a metal. It may be used for isomerizing saturated hydrocarbons at low temperature over long periods.
摘要:
GEM-POLYMETHYLCYCLOHEXANES ARE PRODUCED BY A PROCESS OF CONTACTING CERTAIN ALKYLCYCLOHEXANES UNDER ANHYDROUS CONDITIONS WITH A FRIEDEL-CRAFTS CATALYST AND AN EFFECTIVE AMOUNT OF A PROMOTER FOR THE CATALYST SELECTED FROM HYDROGEN HALIDE, ALKYL HALIDES, OLEFINS AND MIXTURES THEREOF AT TEMPERATURES IN THE RANGE OF 0 TO 70*C. THE CONTACT TIME IS GENERALLY FROM 0.1 TO ABOUT 10 HOURS.
摘要:
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.

摘要:
The present invention relates to supported superacidic catalysts comprising C.sub.4 -C.sub.18, preferentially C.sub.6 to C.sub.12, perfluorinated alkanesulfonic acid absorbed on suitable supports, such as fluoridated alumina, alumina silica and other chalcides having bonded thereto subsequently a Lewis acid compound selected from the higher valency fluorides of the elements of Groups IIA, IIIA, IVB, VA or VIB of the Periodic Table. The invention includes a process for catalytic transformation of hydrocarbons.
