研究了在非均相催化剂磷酸三钾存在下，在亚临界甲醇中通过大豆油酯交换生产生物柴油。结果表明，磷酸三钾对大豆油酯交换反应表现出较高的催化活性。系统研究了反应变量，包括反应温度、甲醇与油的摩尔比、催化剂用量以及大豆油中的水和油酸浓度对脂肪酸甲酯（FAME或生物柴油）产率的影响。在最佳条件下，例如温度220℃、甲醇与油摩尔比24:1，仅用1wt%的K3PO4，在30分钟内就获得了95.6%的FAME收率。 (C) 2011 Elsevier Ltd. 保留所有权利。
Biodiesel production from soybean oil transesterification under the presence of a heterogeneous catalyst tri-potassium phosphate in subcritical methanol has been studied. The results showed that tri-potassium phosphate exhibited high catalytic activity for the transesterification of soybean oil. The effects of reaction variables, including the reaction temperature, the molar ratio of methanol to oil, the catalyst amount, and the water and oleic acid concentrations in the soybean oil, on the yield of fatty acid methyl ester (FAME or biodiesel) were systematically investigated. Under the optimal conditions, e.g., the temperature of 220 degrees C and methanol to oil molar ratio of 24:1, 95.6% of the FAME yield was obtained in 30 min with only 1 wt% K3PO4.
