摘要

在苯甲酸烷基酯与甲醇、乙醇、苯甲醇和环己醇以及植物油与甲醇和乙醇的酯交换反应中，研究了碱金属碳酸盐、原位生成的碳烯和阴离子酸盐的催化作用。与甲醇的催化反应在室温下进行，产率接近定量。在碳酸钾存在下，植物油与少量甲醇或乙醇（3.2当量）在室温下发生反应，可产生高产率的生物柴油燃料，适合工业使用。

Catalysis of the Transesterification Reaction of Alkyl Benzoates and Vegetable Oils by Carbonates, Carbene, and Anionite

The catalytic effect of alkali metal carbonates, in situ generated carbene, and anionite in the transesterification reaction of alkyl benzoates with methanol, ethanol, benzyl alcohol, and cyclohexanol, as well as vegetable oils with methanol and ethanol was studied. Catalytic reactions with methanol occur at room temperature with yields close to quantitative. The reactions of the vegetable oils in the presence of potassium carbonate with small amounts of methanol or ethanol (3.2 eq) at room temperature lead to high yields of biodiesel fuel and are suitable for industrial use.
