| 摘要 |
The present invention relates to a process for the manufacture of a saturated primary alcohol from an unsaturated aliphatic ester comprising the steps of:
a) Providing an aliphatic ester having at least one carbon-carbon double bond;
b) Carrying out a metathesis of said ester in the presence of a ruthenium carbenebased catalyst thereby obtaining a first reaction mixture;
c) Adding a ligand and a base to the first reaction mixture, wherein the ligand comprises at least one donor atom chosen from the group consisting of a nitrogen atom and a phosphorus atom thereby obtaining a second reaction mixture comprising an ester product resulting from the metathesis reaction ;
d) Carrying out a homogeneous hydrogenation of the ester-product resulting from the metathesis, thereby obtaining a saturated primary alcohol. Further, the present invention relates to a catalyst for the hydrogenation of esters and to a process for the hydrogenation of esters using said catalyst. |
