Abstract
Vegetable oils are hydrogenated with mixed copper and nickel catalyst compositions. Oils with linolenate contents of about 7 percent are partially hydrogenated to form liquid oils containing no linolenate with selectivities only slightly lower than those with copper catalysts alone and with significantly accelerated hydrogenation rates.
