64693-3982 ABSTRACT This invention discloses improved heterogeneous acid catalysts and a method for preparing these catalysts. A heterogeneous acid catalyst has been prepared by treating a carrier material with a solution containing a fluorocarbonsulfonic acid polymer dissolved in a suitable solvent, removing the solvent, and heat treating the coated carrier in such a way so as to prevent the polymer from being leached off the carrier. The final heat treatment of the composition to prevent the polymer from redissolving comprises an improvement in the preparation of a heterogeneous catalyst. 33,960-F
