Abstract

1387748 Isomerisation catalyst EXXON RESEARCH & ENG CO 25 May 1972 [25 June 1971] 24647/72 Heading B1E [Also in Division C5] A catalyst, used for isomerising hydrocarbons, comprises (a) at least one Lewis acid of the formula MX n where M is selected from Ti, and the elements of groups V and VIB, X is halogen and n is 3 to 6; and (b) a Bronsted acid selected from fluorosulphuric acid, chlorosulphuric acid, trifluoromethane sulphonic acid and trifluoroacetic acid and mixtures thereof. A liquid diluent, such as sulphuryl chloride fluoride, sulphuryl fluoride, or fluorinated hydrocarbns, may be present, or the catalyst may be supported on an inert support such as fluoride-coated Al 2 O 3 , or aluminosilicates. Lewis acid components used in the Examples are SbF 5 , AsF 5 , TaF 5 , NbF 5 , VF 5 , TiF 4 and MoF 6 .
