It was experimentally determined for the first time that, for noncatalytic biodiesel synthesis, the dependence of the partial pressure of methanol on the mole fraction of methanol in rapeseed oil shows a pronounced negative deviation from Raoult’s law. Investigation of the change in the partial pressure of methanol in the noncatalytic reaction of the transesterification of rapeseed oil in 8 h of the reaction at 220°C demonstrated that the efficiency of the increase in the molar excess of methanol decreases, and, at a more than 10-fold molar excess, the amount of the reacted methanol remains unchanged.

非分析性生物柴油在亚临界甲醇中合成效率的实验与计算研究

首次通过实验确定，对于非催化生物柴油合成，甲醇分压对菜籽油中甲醇摩尔分数的依赖性显示出与拉乌尔定律的明显负偏差。对菜籽油酯交换反应的非催化反应中甲醇分压在 220°C 反应 8 h 中的变化的研究表明，甲醇摩尔过量增加的效率降低，并且，在更多超过 10 倍摩尔过量，反应的甲醇量保持不变。
