1500759 Hydrogenation of vegetable oils INSTITUT DES CORPS GRAS (ITERG) 11 April 1975 [12 April 1974] 15002/75 Heading C5C [Also in Division B1] An unsaturated vegetable oil is treated for selective hydrogenation of polyunsaturated components in the presence of a catalyst comprising a dispersion of micrometallic (i.e. particle size 10-100 microns), ferromagnetic cobalt dispersed in a matrix of fat and formed by decomposing dicobaltoctacarbonyl in a vegetable oil (suitably the same oil as that to be hydrogenated) at elevated temperatures and under a superatmospheric pressure of hydrogen, and on completion of the hydrogenation treatment, the cobalt is separated from the hydrogenated products by the action of a magnet or electromagnet.The vegetable oil may be soya, linseed, colza, cottonseed or sunflower seed oil.An exemplified hydrogenation is the treatment of a crude soya oil containing 0À6% wt. of free fatty acids and 100 p.p.m. of phosphorus at 180-230‹ C. and a hydrogen pressure of 5-15 bars.
