| Abstract: | Catalytic esterification reaction of propionic acid with ethyl alcohol by TiSiW 12 O 40 /TiO 2 has been studied.The effect of catalyst amount,reaction time and molar ratio of alcohol and acid on the yield of ester are discussed.The optimum reaction conditions were found as follows:the molar ratio of ethyl alcohol to propioonic acid was 1.4∶1,quantity of catalyst 2.0%(wt% of alcohol and propionic acid),reaction temperature was about 78 ℃～85 ℃ and reaction time was 1.0 h.The yield of ethy propionate is 50.3%. |
