Abstract
Maleic acid and/or other hydrogenatable precursors are hydrogenated in the presence of a noble metal catalyst to 1,4-butanediol. The production and yields of 1,4-butanediol are enhanced by the addition of iron to the hydrogenatable precursor feed.
Claims12
A process for the production of 1,4-butanediol comprising catalytically hydrogenating a hydrogenatable precursor in contact with a hydrogen-containing gas and a hydrogenation catalyst comprising at least one noble metal of Group VIII of the Periodic Table, selected from the group consisting of palladium, ruthenium, rhodium, osmium, iridium and platinum wherein iron is added to the hydrogenatable precursor.
