Abstract: Synthesis of Tributyl Citrate under the catalysis of [Hmim]+[HSO4]- was investigated. The optimum reaction conditions were as follows:15% catalyst based on the reactants, n(butyl alcohol):n(citric acid)=6:1, cyclohexane as water-carrying agent, reaction temperature 110, and reaction time 7 h. Under these conditions, the yield of product was above 97%. The catalyst can be reused 10 times. The structure of product was characterized by FT-IR 1H NMR. The quality of Tributyl Citrate synthesized in this paper is superior to general commercial products with low chrominance value, similar acid value and moisture.
