The great challenges of modern industry and the environment make it important to develop sustainable energy resources with low cost. In this work, a cleaner enzymatic procedure for biodiesel production was developed through the utilization of a biocompatible and hydrophilic ionic liquid [Choline][H₂PO₄]. This ionic liquid can be synthesized from cheap raw materials through simple neutralization procedures, and it has been proved to be well biocompatible. The utilization of this ionic liquid in Novozym 435 catalyzed biodiesel production makes the reaction and work-up procedures very simple, because its hydrophilicity can lead to the implementation of a pseudo homogeneous reaction and then heterogeneous separation. Various oil resources such as triolein, sunflower oil and castor oil can all be converted to biodiesels with high yields. After the completion of reaction, both the ionic liquid and Novozym 435 can be recycled and reutilized for at least five cycles without a significant activity decrease. In addition, this reaction system can be conveniently scaled up to the multi-gram level with high efficiency and feasible separation. Overall, the above mentioned benefits make this ionic liquid based enzymatic system cleaner for the production of biodiesel and promising for further industrial applications.

通过生物相容的亲水性离子液体触发的轻松分离程序，可更清洁地酶促生产生物柴油

现代工业和环境的巨大挑战使得以低成本开发可持续能源成为重要。在这项工作中，通过利用生物相容性和亲水性离子液体[胆碱] [H ₂ PO ₄ ]，开发了一种用于生产生物柴油的更清洁的酶促程序。]。这种离子液体可以通过简单的中和程序由廉价的原料合成，并且已经证明具有良好的生物相容性。在Novozym 435催化的生物柴油生产中利用这种离子液体，使反应和后处理程序非常简单，因为其亲水性可导致进行假均相反应，然后进行非均相分离。三油精，葵花籽油和蓖麻油等各种石油资源都可以高产率转化为生物柴油。反应完成后，离子液体和Novozym 435均可循环使用至少5个循环，而活性没有明显下降。此外，该反应系统可以方便地按比例放大到克数级，且效率高且分离可行。总体，
