Ozonolysis of Olefins, V : Emulsion Ozonization of Methyl Linoleate and Methyl Linolenate in Aqueous Alkaline Hydrogen Peroxide

Article abstract of DOI:10.1007/BF00811471

The ozonolysis of methyl linoleate and methyl linolenate in neutral and alkaline aqueous emulsions of hydrogen peroxide was investigated.Besides the expected products such as dimethyl malonate (3b), dimethyl azelate (3h) and methyl hexanoate (2a) further homologous methyl esters of dicarboxylic acids (3a-g), oxo carboxylic acids (4a, b, e-h) and hydroxy carboxylic acids (4c, d) could be detected by GC/MS analysis.Furthermore a method for separation of 8-hydroxyoctanoic acid (4d) by methylation and extraction of the reaction mixture containing the ozonolysis products is described. Keywords.Ozonization; Fatty esters; 8-Hydroxyoctanoic acid.
