Abstract
A process for the reduction of ketones or aldehydes to alcohols has been developed. The process involves contacting the ketone or aldehyde with a primary or secondary alcohol and a catalyst at reduction conditions. The catalyst is a molecular sieve having the empirical formula: EQU (M.sub.w Sn.sub.x Ti.sub.y Si.sub.1-x-y-z Ge.sub.z)O.sub.2 where M is a trivalent metal such as aluminum or boron. These molecular sieves have a microporous three dimensional framework structure of at least SiO.sub.2 and SnO.sub.2 tetrahedral units, a crystallographically regular pore system and the characteristic x-ray diffraction pattern of zeolite beta.
