Methyl linoleate was isomerized with iron pentacarbonyl catalyst. Solid fatty acids composed mainly of trans-trans conjugated dienoic acid were separated from the reaction product by low-temperature crystalization. Methyl esters of the solid fatty acids were oxidized in acetone by potassium permanganate. The oxidation products included the monobasic acids, caproic and heptanoic acids, and the dibasic acids, azelaic, sebasic, and oxalic acids. From the analysis of the oxidation products, it is considered that Δ9 : 10, 11 : 12 and Δ10 : 11, 12 : 13 octadecadienoic acids are present in the solid fatty acids separated from the product of isomerization of methyl linoleate with iron pentacarbonyl catalyst.
