| Research Abstract |
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.
