Biodiesel Production of Garcinia Mangostana Linn. seeds by Two-Phase Solvent Extraction and Alkali-Catalyzed Transesterification

The present study introduced the potential used of Garcinia Mangostana Linn. seeds as feedstock for bio-diesel production. The preparation of biodiesel by two-phase solvent extraction (TSE) and alkali-catalyzed transesterification was studied. The important factors including catalyst concentration, ratio of methanol to oil and temperature on conversion FAME were examined respectively by experiments. The results of two-step transesterification showed that the optimal conversion of Garcinia Mangostana Linn. seeds into fatty acid methyl ester (FAME) were at condition of 4:1 methanol/oil volume ratio, 50oC reaction temperature, 0.5% ( catalyst / oil weight ratio w/w) solid base catalyst amount and at 5 minutes reaction time.
