Monoesters from maleic anhydride and ethylene oxide adducts of C1214 s-alcohols (EOAA) were found in this study to be quantitative yield at a reaction temperature lower than 70°C with a sodium acetate catalyst. At a reaction temperature exceeding 100°C, the diesters formed by successive reaction lowered the yield of the monoesters. The present results were obtained by potentiometry for determination of total acid, maleic acid and monoster. The reaction kinetics are also discussed.
