Abstract
This invention relates to conversion processes which take place in the presence of solid acid catalysts, e.g., hydrocarbon conversion processes. More specifically, this invention relates to a liquid phase process for the alkylation of aromatic hydrocarbons, with olefin, e.g., ethylene, propylene, etc., in the presence of a polyfluorosulfonic acid catalyst.
Claims7
A liquid phase process for the alkylation of an aromatic hydrocarbon with an olefin which comprises contacting said aromatic hydrocarbon and said olefin, at reaction conditions, in the presence of a copolymer of a perfluorovinyl ether and tetrafluoroethylene containing pendant sulfonic acid groups, as catalyst.
A liquid phase process for the preparation of ethylbenzene which comprises contacting an ethylene feed stream with a benzene feed stream at a reaction temperature of between about 50.degree. and about 200.degree. C. in the presence of an unsupported catalyst comprising a copolymer of a perfluorovinyl ether and tetrafluoroethylene containing pendant sulfonic acid groups.
A liquid phase process for the preparation of ethylbenzene which comprises contacting an ethylene feed stream with a benzene feed stream at a reaction temperature of between about 0.degree. and about 200.degree. C. in the presence of an unsupported catalyst comprising a copolymer of a perfluorovinyl ether and tetrafluoroethylene containing pendant sulfonic acid groups.
