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.
