Due to the damaging environmental impacts resulting from direct entry of mineral lubricants into the environment, the use of bio-lubricants as a sustainable and renewable alternative to mineral lubricants is necessary; therefore, bio-based lubricants play an important role in overcoming existing challenges and reducing energy consumption. The present research has been conducted to intensity the production process of TMPTE (trimethylolpropane triester) from rapeseed methyl ester under the influence of ultrasonic irradiation. Ultrasound irradiation is one of the efficient and new methods to intensify the TMPTE production reaction. Ultrasound significantly intensifies the overall process with reduction in energy consumption. The response surface methodology was used for the multi-objective optimization of the process input variables in order to obtain the highest yield with the lowest energy consumption. The optimized results of this experiment reveal that with the amplitude of 82%, cycle of 40%, and reaction time of 60 min a bio-lubricant yield of 82.21% with an energy consumption of 116.7 kJ is obtained.

由于矿物润滑剂直接进入环境所造成的破坏性环境影响，有必要使用生物润滑剂作为矿物润滑剂的可持续和可再生替代品；因此，生物基润滑剂在克服现有挑战和减少能耗方面发挥着重要作用。已经进行了本研究以增强在超声辐射的影响下由油菜籽甲酯生产TMPTE（三羟甲基丙烷三酯）的过程。超声辐射是增强TMPTE生产反应的有效和新方法之一。超声波显着增强了整个过程，同时降低了能耗。响应面方法用于过程输入变量的多目标优化，以便以最低的能耗获得最高的产量。该实验的优化结果表明，在振幅为82％，循环为40％，反应时间为60分钟的情况下，获得的生物润滑剂产率为82.21％，能耗为116.7 kJ。
