Research description
The use of bio renewable feedstocks seems to be promising to overcome the dependence on
fossil-fuel resources for energy and chemical building blocks. The studies about the
production of HMF (5-hydroxymethylfurfural) as biofuel and chemicals have increased
greatly. Recently, researchers have investigated the efficient processes to produce high yield
of HMF using monophasic system, biphasic system, and also ionic liquid solutions. Many
researchers have examined various solvents, searched new catalysts, utilized more abundantly
available bio material, and studied the mechanism and kinetics of the dehydration process of
HMF production. However, few studies have been investigated the HMF production process
on the thermodynamics insights. It is still needed the thermodynamic data in various solvents
tested.
This study focuses on the study of liquid-liquid equilibria (LLE) of HMF in aqueous-organic
biphasic systems, various ionic liquid solutions, and deep eutectic solvents. The phase
equilibrium data are needed for the rational design and optimal separation operation of HMF
from the extraction solvent. Moreover, the reliable thermodynamic models are also needed to
enhance the operational efficiency of the separation process and to reduce the production
costs. Therefore, the NRTL and UNIQUAC model are used in this study to correlate the
experimental phase equilibrium data. In addition, the COSMO-RS model will also be used for
the predictions.
