功能化季铵盐离子液体在制备生物柴油中的应用
Application of Synthesis Biodiesel by Functional Qauternary Ammonium Ionic Liquid
摘要
Abstract
6 kinds of SO3 H- quaternary ammonium ionic liquids were prepared. Their IR and NMR spectra showed that the structure were in accordance with the theory. Besides the TG curves showed that they were stable and all the decomposition temperature were above 200 'C. Biodiesel was synthesized with triolein and methanol catalyzed by the 6 kinds of ionic liquids prepared. The effects of reaction time, mole ratio of methanol to oil and ionic liquids dosage on catalytic activity were investigated. Under the congditions of the mass fraction of ionic liquid 7%, mole ratio of methanol to oil 12 ' 1. Temperature 65 'C and reaction time 24 h, the ionic liquid [n-But3N(CH2)3SO3H][P-CH3(C6H4)SQ3]showed the best catalytic activity and the yield of fatty aid methyl ester reached 92. 04%.关键词
