Title:
METHOD FOR CATALYTICALLY HYDRATING ORGANIC COMPOUNDS AND SUPPORTED CATALYST USED IN SAID METHOD
Document Type and Number:
WIPO Patent Application WO2002036260
Kind Code:
A8
Abstract:
The invention relates to a method for catalytically hydrating an organic compound, especially an unstable organic compound, in the presence of a supported catalyst that is provided with a coating that contains ruthenium as the active metal and a total of 0.01 to 30 % by weight of active metals. The aim of the invention is to increase stereoselectivity and catalyst service life. To this end, a supported catalyst is used whose oxide-, carbide-, nitride- or silicate-containing support material, prior to being charged with at least one active metal, has a BET(N2) surface of less than 10 m<2>/g, preferably 0.1 to 5 m<2>/g, with the exception of diatomaceous earth with a BET(N2) surface of greater 2 m<2>/g, and whose ruthenium content constitutes at least 50 % by weight, preferably at least 99 % by weight, of the active metals. The invention further relates to the aforementioned supported catalysts. The method and catalysts according to the invention are especially suitable for hydrating polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.
