ABSTRACT:
This invention provides a catalyst product for hydrocarbon conversion reactions and a method for reacting hydrocarbons employing such catalyst product. The catalyst product is a composite of a perfluorinated polymersulfonic acid and an ion-stabilizing agent such as hexafluoroisopropanol or trifluoroacetic 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.
