In this study, microwave assisted transesterification of Pongamia pinnata seed oil was carried out for the production of biodiesel. The experiments were carried out using methanol and two alkali catalysts i.e., sodium hydroxide (NaOH) and potassium hydroxide (KOH). The experiments were carried out at 6:1 alcohol/oil molar ratio and 60°C reaction temperature. The effect of catalyst concentration and reaction time on the yield and quality of biodiesel was studied. The result of the study suggested that 0.5% sodium hydroxide and 1.0% potassium hydroxide catalyst concentration were optimum for biodiesel production from P. pinnata oil under microwave heating. There was a significant reduction in reaction time for microwave induced transesterification as compared to conventional heating.
本研究采用微波辅助法，以麻疯树籽油为原料，甲醇为醇解试剂，氢氧化钠（NaOH）和氢氧化钾（KOH）为碱催化剂，进行酯交换反应制备生物柴油。在醇油摩尔比为 6:1、反应温度为 60°C 的条件下，考察了催化剂浓度和反应时间对生物柴油产率和品质的影响。结果表明，在微波加热条件下，0.5%NaOH 和 1.0%KOH 为制备麻疯树籽油生物柴油的最佳催化剂浓度。与传统加热相比，微波诱导酯交换反应的反应时间显著缩短。
