| Abstract: | Phosphotungstic heteropoly acid catalysts supported on SBA-15 were prepared adopted impregnation method and used to catalyze the esterification reaction between citric acid and ethanol.The optimum reaction conditions was investigated,and the results indicated that the supported phosphotungstic heteropoly acid catalyst had high activity,the yield of triethyl citrate was over 90% under the condition: reflux reaction time 3h,n(citric acid):n(ethan01)=1:4,catalyst dosage 1.0%. |
