Production of tetrahydrofuran-2, 5-dimethanol from isosorbide |
| 摘要 |
Disclosed herein are processes comprising contacting isosorbide with hydrogen in the presence of a first hydrogenation catalyst to form a first product mixture comprising tetrahydrofuran-2,5-dimethanol. The processes can further comprise heating the first product mixture in the presence of hydrogen and a second hydrogenation catalyst to form a second product mixture comprising 1,6-hexanediol. The first and second hydrogenation catalysts can be the same or different. |

1. A process comprising:
a) contacting isosorbide with hydrogen in the presence of a first hydrogenation catalyst at a first temperature between about 150° C. and about 400° C. and at a first pressure between about 500 psi to about 5000 psi to form a first product mixture comprising tetrahydrofuran-2,5-dimethanol. |
