Transformations of peroxide products of oleic acid ozonolysis at treatment with hydroxylamine and semicarbazide hydrochlorides

Abstract

Peroxide products of oleic acid ozonolysis treated with semicarbazide and hydroxylamine hydrochlorides in methanol are predominantly converted into methyl nonanoate and dimethyl nonanedioate, in 2-propanol, into isopropyl nonanoate and monoisopropyl ester of nonanedioic acid, and also into nonanenitrile, in tetrahydrofuran and in a mixture of acetic acid with dichloromethane, into nonanoic and nonanedioc acids, and also in nonanal oxime and 9-(hydroxyimino)nonanoic acid.Oleic [(9Z)-octadec-9-enoic] acid 1 is present in the composition of nearly all natural fats and oils. One of its main sources is olive (~80%), and also sunflower (39%) and cottonseed (35%) oils, in animal fats it constitutes 36-45% of the overall amount of fatty acids [1].
