Conversion of hydroxy fatty acids, prepared from the products of fermentation of long chain hydrocarbons or fatty acids with Torulopsis magnoliae , to dicarboxylic acids with 15 to 18 carbon atoms is described. Both nitric acid oxidation and fission in 85% KOH give yields of 60舑75%, but the products have different compositions. The nature of the compound fermented determines the composition of the hydroxy acids produced and hence that of the derived dicarboxylic acids. A convenient method is presented for hydrolysis of the hydroxy fatty acid sophorosides obtained by fermentation.
