We demonstrated that the addition of co-solvents to an enzymatic BDF synthesis system resulted in a fast and high-yield reaction compared with the conventional synthesis. The effect of co-solvents on prevention from aggregation of immobilized enzyme resins and de-emulsification of by-product glycerin phase were clarified. Furthermore, we showed that the reaction yield of our proposal technology exceeded 99%. Various phase equilibrium data were measured to suggest a solvent extraction method for recovery of methanol from the glycerin phase. Finally, the integration of the present BDF synthesis and solvent extraction was evaluated in terms of energy saving.

我们证明，与传统合成相比，在酶促 BDF 合成系统中添加共溶剂可实现快速且高产的反应。阐明了共溶剂对防止固定化酶树脂聚集和副产物甘油相破乳的作用。此外，我们的提案技术的反应收率超过了 99%。测量了各种相平衡数据，以建议从甘油相中回收甲醇的溶剂萃取方法。最后，从节能角度对现有的 BDF 合成和溶剂萃取的集成进行了评估。
