Abstract:
The effect of different organic solvents as reaction media for transesterification of palm olein was studied. The organic solvents studied used were: dimethylsulphoxide (log P-1.3), tetrahydrofuran (log P 0.49), dietylether (log P 0.85), heptane (log P 4.0) and isooctane (log P 4.52). Transesterification reaction was carried out at 60°C and 200 rpm for 6 hours using an immobilized lipase from Aspergillus niger as catalyst.
