Hydrogenation of lecithin

Hydrogenation of lecithin is usually done under conditions to reach iodine values of 10-20 in the presence of a nickel or palladium catalyst and a suitable solvent (e.g., ethyl acetate) at 75-85°C under 70 atmospheres pressure. Bromine or chlorine also readily adds across double bonds yielding products useful in lubricant formulations. Iodine can be added by warming granular lecithin dissolved in acetic acid in the presence of iodine and magnesium or aluminum catalyst (58).
