Sulfonated Ordered Mesoporous Carbon as a Stable and Highly Active Protonic Acid Catalyst

Abstract

Covalent attachment of sulfonic acid-containing aryl radicals on the surface of ordered mesoporous carbon (CMK-5), leads to a solid acid catalyst with a high acid density. The material exhibits high surface area, uniform pore size distribution, high activity and good stability for acid-catalyzed reactions, such as esterification and condensation.
