CATALYSTS FOR MALEIC ACID HYDROGENATION TO 1,4-BUTANEDIOL

摘要

The invention containing the active ingredient at least one hydrogenation catalyst on a support containing a rutile crystal titanium dioxide on the a hydrogenation catalyst and hydrogen -containing gas and hydrogenation of 1,4-butanediol by contacting the precursor (BDO) , and in some cases, gamma -butyrolactone (GBL) and / or tetrahydrofuran (THF) to produce , as the hydrogenation relates to a catalytic hydrogenation method of the precursor .
