説明

The side reaction during catalytic hydrogenation of oil was investigated. Soybean oils with peroxide number 5 and 101 were hydrogenated and deoderized. The deoderized oil was fractionated into polar glyceride and non-polar glyceride by column and thin-layer chromatography.<BR>The polar glyceride was converted to methylester and again fractionated into polar acid ester and non-polar acid ester.<BR>The IR spectra and Rf on TLC of the polar acid ester were identical with those of ω-hydroxy acid ester which was derived from oleyl alcohol. In the non-polar acid, the lower fatty acid which had not been contained in original soybean oil was found by gas chromatography. These lower fatty acid and polar acid were found only in the hydrogenated oil from the oil of peroxide number 101 and not found from the oil of peroxide number 5.<BR>The mechanisms of formation of those acids were discussed.
