英文摘要：

Catalytic synthesis of tributyl citrate,with citric acid and butanol as material,using sodium hydrogen sulfate/assistant-catalyat as catalyst was studied.The effects of activator loadings on the reaction was investigated.Citric acid/butanol molar ratio and reaction temperature on the esterification reaction were investigated,too.The optimum reaction condition was obtained as following：catalyst loading=4.1%～4.6% （sodium hydrogen sulfate/assistant-catalyat molar ratio=1.0∶8）,citric acid/butanol molar ratio=0.1∶0.48,reaction temperature of end point =150～155℃,and reaction time=1.6h,efficiency of esterification=97%,activator was cheapness,facile,and repetition=5,regeneration easy,causticity was small,pollution of environment was small.
