Preparation of Biodiesel from Waste Cooking Oil Catalyzed by Basic Ionic Liquid

Abstract:

A basic ionic liquid tetra butyl phosphonium hydroxide was applied as a catalyst for biodiesel production from waste cooking oil by transesterification process and the yield 82% was achieved. The ionic liquid was used four times without any dramatic decrease in ester yield. And the methyl ester was checked by ¹H NMR. Keywords: Biodiesel, waste cooking oil, transesterification, ionic liquid.
