The extent of overoxidation of half‐esters of dicarboxylic acids is governed mainly by the nature and proportions of the oxidizing agent employed and not by reaction temperatures. In procedures which produce overoxidation, this occurs mainly at the time of the scission of the double bonds and no method is known to prevent it. The acetone permanganate procedure overoxidizes monocarboxylic acids (MCA), dicarboxylic acids (DCA) and half esters of DCA. The acetic acid‐acetone permanganate procedure overoxidizes DCA but not MCA half‐esters of DCA or azelaoglycerides. The DCA corresponding to the first double bond in unsaturated fatty acids (UFA) can be isolated quantitatively if the esters or triglycerides are oxidized by the latter procedure.
