Abstract: Tributyl citrate(TBC) was synthesized with citric acid and butyl alcohol as raw materials and p-toluene sulfuric acid as esterification catalyst.The effects of the reactant ratio,catalyst quantity,reaction time and reaction temperature on the product yield were investigated.The proper reaction conditions were the molar ratio of citric acid to butyl alcohol was 1∶ 5,the amount of catalyst was about 2% of the quality of citric acid,and reaction time was 4.0 h.The yield of the ester could reach 98.9%.The initial reaction product was neutralizatized by sodiun carbonate and decompressed distillation,it could meet requirement with high quality.In this condition,the esterification rate was 98.9%.
