Abstract
The reaction of esterification by maleic anhydride in methyl ethyl ketone in the presence of triethylamine is proposed for the determination of alcohol hydroxyl groups. The equivalent amount of maleic anhydride that entered into the reaction is determined spectrophotometrically by the reaction with 2-methylimidazole. In the determination of hydroxyl groups in epoxy-dian resins, maleic anhydride is determined by the potentiometric titration with alkali after hydrolysis with water by the first potential jump.
