Title:
錫置換ゼオライト・ベータを用いたケトン類のエステル類への酸化
Document Type and Number:
Japanese Patent JP4741776
Kind Code:
B2
Abstract:
Applicants have developed a process for the oxidation of ketones to esters. The process involves contacting the ketone with hydrogen peroxide and a catalyst at oxidation conditions. The catalyst is a molecular sieve represented by the empirical formula:where M is a trivalent metal such as aluminum or boron. These molecular sieves have a microporous three dimensional framework structure of at least SiO2 and SnO2 tetrahedral units, a crystallographically regular pore system and the characteristic x-ray diffraction pattern of zeolite beta.
