Perfluorinated ion-exchange microcomposite catalysts modified with Lewis acid
This invention concerns a modified porous microcomposite comprising a perfluorinated ion-exchange polymer entrapped within and highly dispersed throughout a network of inorganic oxide wherein the network and optionally the pendant groups of the polymer have been modified with a Lewis acid. These modified microcomposites can be used in catalyst compositions for various chemical processes, such as in the alkylation or acylation of aromatics.
