Lipase-catalyzed biodiesel production from soybean oil in ionic liquids

Abstract

Production of biodiesel in ionic liquids through immobilized Candida antarctica lipase-catalyzed methanolysis of soybean oil was demonstrated. Among tested 23 ionic liquids, the highest fatty acid methyl esters (FAMEs) production after 12 h at 50 °C was achieved in (Emim)(TfO). The production yield of 80% was eight times higher compared to the conventional solvent-free system. It was around 15% higher than the FAMEs production system using tert -butanol as an additive. The optimum substrate molar ratio of methanol to soybean oil for FAMEs production in (Emim)(TfO) was found to be 4:1. Our results of high production yield in ionic liquids show that ionic liquids are potential reaction media for biodiesel production.
