ABSTRACT:
This invention is a method for producing an acidic catalyst product which may be used for hydrocarbon conversion reactions and a method for reacting hydrocarbons employing such catalyst product. The method comprises the step of contacting the perfluorinated polymersulfonic acid with a mixture of the anion-stabilizing agent and its corresponding anhydride, the stabilizing agent being a fluorinated carboxylic acid. The composite catalyst has a significantly higher Bronsted acidity than the perfluorinated polymersulfonic acid. When the catalyst composite is used to catalyze the alkylation of toluene with 1-hexene, for example, the rate of alkylation is from about 20 to 30 times greater than using the perfluorinated polymersulfonic acid alone.
