| Abstract：The esterification of citric acid and n-butanol was carried out with tetrabutyl-titanate as the catalyst. The main factors, the quantity of catalyst, reaction temperature, molar ratio of reactants and reaction time, which effected the esterification, were discussed. The optimum reaction conditions were determined as follows: molar ration of citric acid to n-butanol 1:4.1, reaction temperature 150℃, reaction time 4.5?h, the quantity of catalyst accounted for 1.2% of citric acid, and the final conversion was ... |
