Abstract

The refined rape-seid oil was oxidized with dried air at 96°C, for 1224 hr. The volatile carbonyl compounds evolved were caught in two traps of 2, 4-dinitrophenylhydrazine solution. Hydrazone compounds were then passed through alumina column with benzene to collect only mono-carbonyl compounds. C6- and C8-unsaturated carbonyl compounds in this monocarbonyl compounds were separated with preparative paper-chromatography and re-crystalized. The constituents of these compounds were investigated by U. V., I.R.-spectra and paper-chromatography of oxidation product with ozone. As a result;<BR>1) The constituents of C6-unsaturated carbonyl compounds were CΔ : 26, CΔ : 36 and CΔ2 : 46.<BR>2) The costituents of C8-unsaturated carbonyl compounds were CΔ : 28, CΔ2 : 48 and trace CΔ : 58.
