以肉豆蔻酸为催化剂，对菜籽油与甲醇同时进行酯交换和酯化反应进行了研究。研究了反应温度（120、150和170 °C）和油中初始游离脂肪酸含量（0、10和20重量%）对反应速率的影响。发现催化剂提高了所有反应的速率。无溶剂法制备的硫酸化氧化锆在同时反应中表现出比传统方法更高的活性。甘油三酯中10重量%游离脂肪酸的存在增加了反应速率和最终总脂肪酸甲酯含量，并表明“非催化”反应可能是可行的。
Simultaneous transesterification and esterification of rapeseed oil with methanol in the presence of myristic acid was investigated. The effect of reaction temperature (120, 150 and 170 °C) and the effect of initial free fatty acid content in oil (0, 10 and 20 wt%) on reaction rate were studied. The catalysts were found to increase the rate of all reactions. Sulfated zirconia prepared by a solvent-free method exhibited higher activity in simultaneous reaction than the conventional method. The presence of 10 wt% free fatty acids in the triglyceride increased the reaction rate and the final total fatty acid methyl esters content, and suggests that a “non-catalytic” reaction may be feasible.
