Process for the production of 1,3-propanediol by hydrogenating 3 -hydroxypropionaldehyde |
| 摘要 |
A process for the production of 1,3-propanediol by heterogeneously catalyzed hydrogenation of 3-hydroxypropionaldehyde in an aqueous solution at 30 to 180 DEG C, a hydrogen pressure of 5 to 300 bar and a pH value of 2.5 to 7.0, wherein ruthenium on an oxide support is used as the catalyst. |
