Elucidation of structural isomers from the homogeneous rhodium-catalyzed isomerization of vegetable oils.

摘要: The structural isomers formed by the homogeneous rhodium-catalyzed isomerization of several vegetable oils have been elucidated. A detailed study model compound methyl linoleate has performed to correlate distribution conjugated isomers, reaction kinetics, and mechanism reaction. It shown that [RhCl(C8H8)2]2 is a highly efficient selective catalyst for production with high linoleic acid (CLA) content, which desirable in food industry. combined fraction two major CLA [(9Z,11E)-CLA (10E,12Z)-CLA] overall mixture range from 76.2% 93.4%. efficiency selectivity this method along straightforward purification process render approach promising preparation CLA. Proposed improvements recovery reusability will only make more appealing food, paint, coating, polymer industries future.
