Abstract
Mercaptopropyl-functionalized porous silicates were synthesized by the co-condensation of (mercaptopropyl)triethoxysilane and tetramethoxysi lane in the presence of a cationic surfactant. The ordered hexagonal a rrays of channels in the extracted product were microporous (14 Angstr om pore diameter) and contained high concentrations of alkylthiol func tions. It was possible to oxidize the supported thiol groups to sulfon ic acid groups, thus creating a solid acid ion exchanger. The sulfonic -acid functionalized material is an efficient heterogeneous acid catal yst.
