Developement of NMR Based Derivation for Quantification of Epoxy Methyl Oleate

Abstract

Lipid oxidation is the degradation of oxidative lipids which leads to toxic, sour flavours of lipid containing foods. Cis-9-Octadecenoic acid (Oleic acid) derivatives were prepared and characterized. The processes involved were esterification of oleic acid and epoxidation of methyl oleate to oxirane ring. The epoxidation of oleic acid was carried out by using in-situ epoxidation via generated peroxyformic acid (HCOOOH) to produce epoxy methyl oleate. The degree of temperature, the molar ratio of formic acid or hydrogen peroxide and types of catalyst was considered. The products’ structures were confirmed and characterized by 1H-NMR and 13C-NMR. Quantification of the products epoxidised vegetable oils acts as a raw material helps in the synthesis of various chemicals including glycols, polyols, carbonyl compounds and biolubricants because of their oxirane oxygen content and high reactivity of oxirane ring.
