Hydrogenation of Some Vegetable Oils by Scrap Automobile Catalyst

Abstract

Some vegetable oils were hydrogenated with scrap automobile catalyst (SAC) as a catalyst. The optimum reaction conditions (solvent, reaction time, and catalyst amount) were determined. Our results showed that the linoleic acid was reduced to elaidic acid in the sunflower oil. This procedure not only give high yields but also allows recycling of automobile wastes as a catalyst in organic reactions and is representative of green chemistry.
