| Abstract | The hydrogenation of methyl oleate (methyl 9Z-octadecenoate) into oleyl alcohol (9Z-octadecen-1-ol) is carried out in an autoclave at 8.0 MPa and 543 K with Ru-Sn catalysts. The activity and the selectivity of this catalytic system are linked to the preparation method, the nature of the support (alumina, silica, active carbon and zinc oxide) and to the tin content. Selectivities of 50 and 55% to unsaturated alcohol respectively were obtained with a Ru-Sn-B/alumina catalyst resulting from the co-reduction of metallic salts by sodium borohydride and a Ru-Sn/alumina catalyst prepared by a sol-gel method. Our work also showed that a previously unreported transesterification reaction between methyl oleate and oleyl alcohol occurred rapidly and led to a 'higher' ester (oleyl oleate). This side-reaction significantly decreases the selectivity to unsaturated alcohol. Nevertheless, at higher conversion the oleyl oleate is gradually hydrogenated into oleyl alcohol. |
