| Abstract: | The solid acid catalyst SO 2- 4/TiO 2- Fe 2O 3 was prepared and its catalytic properties for the synthesis of tri-n-butyl citrate has been tested. The effects of reaction time, initial molar ratio and catalyst quantity on reaction conversion have been studied. The proper technology parameters for the process are achieved: the molar ratio of butanol to citric acid is 6:1, weight of catalyst was 2.0g (weight of 0.1mol citric acid), the reaction time was 3 hours under stirring and refluxing, then the conversion of citric acid is above 94.5%, and the purity of resulting product is over 99%. |
