In this study, the use of a mixture of acyl acceptors (dimethyl carbonate, methanol and ethanol) under pressurized conditions to obtain fatty acid esters (FAEs) was investigated. The influence of varying the proportions of acyl acceptors and the temperature applied in the reaction was evaluated using commercial oil. For the proportions that resulted in the maximum FAE yield (Y_FAE), the crambe oil was extracted using pressurized liquid extraction (PLE) and characterized. The extraction product (oil + acyl acceptors) was then subjected to the reaction step. The addition of alcohols to dimethyl carbonate favored the Y_FAE, a higher proportion of ethanol made the reaction product less susceptible to thermal decomposition and it was possible to obtain ~86 % of Y_FAE at 275 ºC. The oil obtained in the PLE had higher contents of phytosterols and γ-tocopherol. Thus, the extraction product had greater stability and Y_FAE of ~94 % was obtained without thermal decomposition.

在这项研究中，研究了在加压条件下使用酰基受体（碳酸二甲酯、甲醇和乙醇）的混合物来获得脂肪酸酯 (FAE)。使用商业油评估了改变酰基受体的比例和反应中应用的温度的影响。对于导致最大 FAE 产率 (Y _FAE ) 的比例，使用加压液体萃取 (PLE) 萃取海葵油并进行表征。然后使萃取产物(油+酰基受体)经受反应步骤。向碳酸二甲酯中添加醇有利于 Y _FAE，较高比例的乙醇使反应产物不易受热分解，并且可以获得约 86 % 的 Y _FAE在 275 摄氏度。PLE中获得的油具有较高的植物甾醇和γ-生育酚含量。因此，萃取产物具有更高的稳定性，并且在没有热分解的情况下获得了约 94% 的Y _{FAE 。}
