A method for the analysis of hydroxyls employing esterification with 3,5‐dinitrobenzoyl chloride, followed by titration with tetrabutylammonium hydroxide, has been applied to mono‐ and diglycerides. Pure mono‐ and dipalmitins were recovered quantitatively. A commercial glyceryl dioleate was analyzed by this method and the A.O.C.S. pyridine‐acetic anhydride procedure with similar results.
