Abstract

Silver-resin column chromatography, preceded by preparative gas-liquid chromatography to remove unconjugated esters, has been used to separate conjugated methyl octadecadienoates intocis,cis-, cis,trans-, andtrans,trans- isomers, also methyl eleostearate into a- and β-isomers in 91 to 100% purity.
