【 摘 要 】

In this study, high content of free fatty acid (FFA) from low grade palm oil (LGPO) was treated using deep eutectic solvent (DES). This DES was prepared via mixing of p-toluenesulfonic acid monohydrate (PTSA) with benzyltrimethylammonium chloride (BAC). Various effect of reaction conditions were studied such as catalyst dosage (0.5% to 4.5%), molar ratio (2:1 to 12:1), reaction time (10 to 120 min) and reaction temperature (30 °C to 80 °C). This study exhibited that 2% catalyst dosage, 10:1 molar ratio of methanol to oil, 30 min of reaction time and reaction temperature of 60 °C were the optimum condition to reduce the FFA content to less than 2%.
