Abstract
Beta-eleostearic acid and its methyl ester were oxidized with peracetic, perbenzoic or monoperphthalic acid at temperature below 30°C.
The oxidation products were viscous, and their specific gravities were more than 1.
It was considered that epoxy compound is not present in the oxidation products from the data of infra-red spectra and the result of hydrogenation with lithium aluminium hydride, although the products reacted with hydrogen bromide under the condition of Durbetaki's oxyrane oxygen determination method. From the data of infra-red and ultraviolet spectra and from the acid, saponification and hydroxyl values, the oxidation products were estimated as hydroxy-acyloxy compounds. Conjugated diene was found in some of products oxidized with perbenzoic or monoperphthalic acid, and conjugated triene was found in some of products oxidized with monoperphthalic acid from the data of infra-red and ultraviolet spectra.
It was estimated that reactivity of peracids with eleostearic acid or its methyl ester was in the order; peracetic>perbenzoic>monoperphthalic acids.
