Selective hydrogenation into oleyl alcohol of methyl oleate in the presence of RuSnAl2O3

Add time:08/11/2019    Source:sciencedirect.com

The hydrogenation of methyl-9-octadecenoate (methyl oleate) into 9-octadecen-1-ol (oleyl alcohol) was carried out in the presence of RuSnBAl2O3 catalysts at 8.0 MPa and 270°C. The selectivity to unsaturated alcohol (oleyl alcohol) was enhanced significantly by adding tin to ruthernium and reducing the catalyst by a published procedure. But our work showed that a transesterification reaction between methyl oleate and oleyl alcohol (initially formed) not reported in previous works occurred rapidly giving oleyl oleate. This ester was then transformed into oleyl alcohol at a higher conversion of methyl oleate. The result was that the formation of oleyl oleate which occurred on tin species decreased the selectivity of unsaturated alcohol.
