双键型离子液体制备及其催化油酸 合成生物柴油的研究

Abstract

Abstract: A new acidic ionic liquids with double bond ([SO₃H(CH₂)₄VIm] [CF₃SO₃]) was synthesized and used in the esterification reaction of oleic acid to synthesize biodiesel. The effects of reaction conditions on the catalytic synthesis were investigated. The results showed that the optimum conditions were the molar fraction of ionic liquid to oleic acid 5%,molar ratio of methanol to oleic acid 6:1,60℃ and 5 h. Under these conditions,the yield of product was more than 96.07%. The ionic liquid catalyst exhibited a good catalytic activity,and after it was reused five times,the yield of product was over 95%.

Key words: double bonds ionic liquids, catalyst, oleic acid, biodiesel, esterification reaction
