| Abstract: | Tributyl citrate was synthesized from citric acid and n-butanol using solid superacid SO4^2/TiO2/ La^3＋ as catalyst. The results show that the optimum conditions of esterification are as follows： the molar ratio of n-butanol to citric acid was 3.6, usage of catalyst was 0.6%（wt%）, reaction time was 2.0h. And the esterification yeild was 93.1%. |
