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.
