摘要：
The esterification efficiency of several ionic liquids has been investigated to determine the feasibility for the conversion of free fatty acids to alkylester. Five ionic liquid catalysts having strong acidity, BPC[AlCl3], BMIM[Bf(4)], BMIM[Pf(6)], EMIM[Ntf(2)], BMIM[Otf], have been employed in this work. BPC[AlCl3] has the highest esterification efficiency among the ionic liquid catalysts. Over 90% conversion efficiency has been achieved in the esterification of the simulated used cooking oil by BPC[AlCl3] with two hours reaction time. Since BPC[AlCl3] has several advantages such as high esterification activity, ease of separation from reaction mixture and reusability after treatment procedure, it will be a promising catalyst for the conversion of free fatty acids to esters in waste fats.
