Abstract
A process and catalyst for the conversion of hydrocarbons is disclosed. The catalyst is a supported solid perfluorinated polymer containing pendent sulfonic acid groups. The processes include alkylation of isoparaffins, isomerization of normal alkanes, disproportionation of toluene, and the alkylation of benzene.
Claims6
A liquid phase process for the preparation of ethylbenzene which conprises contacting an ethylene feed stream with a benzene feed stream at a reaction temperature of between about 125.degree. C and about 225.degree. C in the presence of a catalyst composition comprising a solid perfluorinated polymer catalyst supported on an inert porous carrier having an average pore diameter of between about 50 A and about 600 A in a weight ratio of catalyst to support of between about 0.1:100 and about 20:100 wherein said catalyst contains a repeating structure selected from the group of:
- ##STR9## where n is 0, 1 or 2;
- R is a radical selected from the group consisting of fluorine and perfluorealkyl radicals having from 1 to 10 carbon atoms;
- and X is selected from the group consisting of:
- [O(CF.sub.2).sub.m ], [OCF.sub.2 CFY] or [OCFYCF.sub.2 ]
- where m is an integer from 2 to 10 and Y is a radical selected from the class consisting of fluorine and trifluoromethyl radical.
