| Abstract: | Ethyl oleate was synthesized by oleic acid and ethanol as raw material,using phostpho-tungstic acid as catalyst.Effects of catalyst composition,loadings of the catalyse,the mole ratio of oleic acid to ethanol and reaction time were investigated.The optimum conditions were as follows: use phostpho-tungstic acid as the catalyst,n(oleic):n(ethanol)=1:6,catalyst dosage 0.4g,reaction time 2h,the yield of esterification rate may up to 96.3%. |
