| SYNTHESIS |
Mesoporous crystalline zeolites prepared by a novel technique could find a wide variety of applications in heterogeneous catalysis, according to authors. They show that large titanium-containing zeolite crystals with a mesopore system are catalytically active in the epoxidation of oct-1-ene and significantly more active in cyclohexene epoxidation than conventional microporous titanium-containing zeolites. After reaction, the crystals are removed from the product mixture by simple filtration. The group uses an excess of zeolite gel and an inert carbon matrix to prepare the crystals. The carbon is removed by combustion
