Title:
METHOD FOR PREPARING RUTHENIUM-CARRYING ALUMINA AND METHOD FOR OXIDIZING ALCOHOL
Document Type and Number:
WIPO Patent Application WO/2003/090926
Kind Code:
A1
Abstract:
A method for preparing a ruthenium-carrying alumina which comprises suspending alumina in a solution containing a tri-valent ruthenium, and then adding a base to the resultant suspension. A ruthenium-carrying alumina is useful as a catalyst for use in contacting an alcohol with molecular oxygen to oxidize the alcohol, and can be used for oxidizing an alcohol at an enhanced conversion and producing a ketone, an aldehyde, a carboxylic acid and the like with improved productivity.
