Research goal

The aim of this research is systematically study the effect of HMF (5-hydroxymethylfurfural) reaction mixture constituents on the liquid-liquid equilibria (LLE) at 313.15 K and atmospheric pressure. The separation factor and distribution coefficient of HMF are also determined from LLE data to interpret the extraction performance. Then, the experimental LLE data obtained are correlated using NRTL thermodynamics model. The reliable thermodynamics model is needed to enhance the operational efficiency of the separation process. Additionally, the phase equilibrium data obtained in this study provide the basis for a rational design and optimal HMF extraction operation.
