Abstract
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 fluorinated 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.
Claims4
An effective, supported solid superacidic catalyst composition for hydrocarbon transformations comprising a C.sub.4 to C.sub.18 perfluorinated alkanesulfonic acid deposited or absorbed on a suitable carrier and having bonded thereto from between about 1 to about 50 percent by weight of the total catalyst composition of a Lewis acid fluoride selected from the elements of Group IIA, IIIA, IVB, VA, VB or VIB of the Periodic Table.
