Synthesis and purification of polyunsaturated triglycerides
1984
Adlof, R.O. | Emken, E.A.
Triglycerides (TG) were prepared by the sodium methoxide-catalyzed interesterification of triacetin and the appropriate methyl ester. Yields were optimized and side-reactions were investigated. Silver resin chromatography, utilizing mixed solvent systems (acetonitrile/acetone) was used to separate the resulting TG/methyl ester mixtures. The isolated TG were analyzed by ultraviolet and infrared spectroscopy and were found to contain no conjugated or trans isomers. They also were analyzed by thin layer chromatography and gas chromatography and found to contain no diacyl-monoacetyl glyceride or other reaction components. Based on higher yield and lack of isomerized byproducts, this procedure was found to be superior in the synthesis of highly unsaturated TG.
