Oxidation catalyst and process for the production of epoxides from olefines, hydrogen and oxygen using said oxidation catalyst

摘要

An oxidation catalyst based on titanium silicalites or vanadium silicalites having a zeolite structure and containing from 0.01 to 30% by weight of one or more noble metals selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum, rhenium, gold and silver has been molded by a compacting shaping process. P P This oxidation catalyst is used for the preparation of epoxides, in particular propylene oxide, from olefins, hydrogen and oxygen.
