Verfahren zur selektiven Haertung von Fetten und Fettsaeuren

摘要

Fats and fatty acids containing diene, triene or polyene fatty acid residues or containing cis monoene residues are hardened or decolorized by hydrogenating them in the presence of a nickel sub sulfide alone or together with molybdenum and/or tungsten sulfides to form a product having a substantial amount of trans monoene residues.
