Abstract

New task-specific ionic liquids, hydroxy-functionalized 1-methyl-3-alkylimidazolium hydroxides, were used as catalysts in the transesterification of rapeseed oil with methanol. In comparison to the well-described 1-methyl-3-butylimidazolium hydroxide [bmim]OH, the new ionic liquids show unexpectedly high catalytic activity. In case of the ionic liquid [glymim]OH, which is structurally similar to glycerol, the conversion of rapeseed oil was nearly 100 %.
