✦ Synopsis

Abstract

Olive oil was converted into methyl esters which were autoxidized at 60 °C. The composition of oxidized products was determined by the comparison of infrared spectra and NMR spectra of the original and acetylated samples, the sample reduced with potassium iodide and the acetylated reduced sample. Oxidized products were separated by preparative thin layer chromatography on silica gel and characterized by selective detection and by infrared spectrometry of the fractions. The oxidation products consisted of hydroperoxido butyl oleate, substituted hydroperoxides, mono‐and disubstituted monomeric derivatives and a small amount of oligomers.

## Abstract The thermal treatment of vegetable oils was studied by gel chromatography on packings of styrene‐divinylbenzene copolymers. Unlike oils with a lower content of polyene acids, those with a high content of polyene acids contained a larger amount of higher oligomers of fatty acids. The gel
