Resumo Inglês:
Classic methodologies for hydrogenation of vegetable oils have traditionally
been carried out by nickel catalysts under high pressure of H2 and high temperature. An
alternative method for hydrogenation of sunflower oil using limonene and palladium-oncarbon was investigated in this study. The use of limonene as a hydrogen donor solvent
was proposed in order to avoid high temperature and high-pressure conditions. The
catalytic transfer of hydrogenation was studied by using 0.5 to 2% of Pd as a catalyst, a
limonene:oil ratio of 3:1, and reaction times from 0.5 to 2 hours. Under these conditions,
high selectivities for oleic acid and low concentrations of stearic acid were obtained.
