Abstract
Copper compositions that are useful as hydrogenation catalysts are disclosed. In particular, the copper compounds are catalysts for the selective hydrogenation of oils that contain unsaturated fatty acyl components such as unsaturated vegetable oils. Methods of preparing the copper compositions are also disclosed. Methods of hydrogenating unsaturated compositions that contain at least two sites of unsaturation using the hydrogenation catalysts, along with products obtained from the hydrogenation reactions described herein are also disclosed.
