A PROCESS FOR THE PREPARATION OF 1,3-PROPANEDIOL BY THE HYDROGENATION OF HYDROXYPROPIONALDEHYDE |
摘要 |
Process for the preparation of 1,3-propanediol by hydrogenation of hydroxypropionaldehyde (HPA) in aqueous solution on a shaped supported catalyst in a solid bed, the concentration of the HPA in the solution being 5 to 100% by weight, and the hydrogenation being carried out at temperatures from 30 to 180 DEG C and hydrogen pressures from 5 to 300 bar and at a pH between 2.5 and 6.5, characterised in that the supported catalyst consists of titanium oxide, on which platinum is present in finely divided form in an amount relative to the support of 0.1 to 5.0% by weight. |
