Abstract

The effects of some process conditions on isomer distributions during the partial hydrogenation of trilinolein with a copper type catalyst were studied. Modest effects on diene isomer distributions were noted by changes in temperature. Pressure and catalyst concentration, however, had little or no effect on diene isomer distributions over the range studied. Distribution of monoene isomers appeared to be insensitive to process conditions and extent of the reaction and suggests an equilibrium reaction. Very small amounts of saturates, if any, were formed during the reactions. The data support a conjugation then hydrogenation mechanism for hydrogenation of glyceryl dienoates with copper catalysts.
