Abstract: 10-Undecenoic acid tetrafluoropropyl ester (UATE) was synthesized from 2,2,3,3-tetrafluoro-1-propanol and 10-undecenoic acid by direct esterification.The UATE was characterized by FT-IR and ¹H NMR.The effects of the reaction temperature,the amounts of tetrafluoropropanol,catalyst and toluene and the reaction time on the yield of UATE were studied.The synthesis process of UATE was optimized through the response surface experimental design.Thus the optimal conditions of synthesis are determined:n (2,2,3,3-tetrafluoro-1-propanol)∶n (10-undecenoic acid) = 3∶1;the amount of concentrated sulfuric acid is 0.5%;the amount of toluene is 7.6 mL;the reaction time is 10 h;the reaction temperature is 138 ℃.Under such condition,the maximum yield of UATE is 78.6%.
