Abstract
The invention relates to sulfonic acid derivatives of crystalline porous materials having uniform pore size with an average pore size greater than 5 Angstroms or a Constraint Index of ten or less. In a preferred embodiment an acid treated crystalline porous material is reacted with a reagent to form the sulfonic acid derivative. The new products can be used as acid catalysts for acid catalyzed reactions. An example is the use of these materials in acid catalyzed etherification of methanol with isobutene.
