Effects of different reaction conditions on the synthesis of tributyl citrate

Yongmei Zhang

The main properties of tributyl citrate have been introduced. Different catalysts that consist of solid superacid SO4 2- /ZnO-TiO2, carbon-based solid acid, modified silica gel supported phosphotungstic acid and phosphotungstic acid have also been introduced. Effects of different reaction conditions such as the amount of catalyst, the molar ratio of citric acid to butanol, the reaction temperature and the reaction time are discussed. The optimum amount of catalyst, the molar ratio of citric acid to butanol, the reaction temperature and the reaction time are beneficial to improve the yield of tributyl citrate.
