Palladium supported catalysts for the selective hydrogenation of sunflower oil

The aim of the study is to hydrogenate selectively the ethyl esters of traditional sunflower oil (SOEE) toward the cis C18:1 isomers, at 40 °C in ethanol. The highest selectivity is obtained over Pd/SiO2 catalysts modified by lead or by addition of amines in the reaction medium.
