Improved process for the hydrogenation of maleic acid to 1,4-butanediol |
| 摘要 |
<p>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.</p> |
