CATALYSTS FOR MALEIC ACID HYDROGENATION TO 1,4-BUTANEDIOL

摘要

This invention relates to a process for catalytically hydrogenatintg hydrogenatable precursor in contact with a hydrogen-containing gas and a hydrogenation catalyst comprising one or more active hydrogenation catalyst components on a support comprising titanium dioxide in the rutile crystalline phase to produce 1,4-butanediol and, optionally, gamma-butyrolactone and/or tetrahydrofuran.
