Lowering the trans-isomer content in hydrogenation of triglycerides of unsaturated fatty acids at ambient temperatures

The selective hydrogenation of the triglycerides of unsaturated fatty acids from vegetable oils has been performed using newly designed low-loaded palladium catalyst. Investigations on the effect of reaction conditions (temperature, pressure, fractional composition) on the trans -isomerization showed that the palladium catalyst unlike conventional nickel catalysts allows to decrease the trans -isomer content in final hydrogenated fat.
