Production of liquid biofuels and high value-added chemicals from biomass is one of the most important challenges nowadays, due to environmental concerns and risk of energy shortages. Recently, several research groups have reported numerous approaches to convert six-carbon sugars (such as glucose and fructose) from biomass into a furan compound called 5-hydroxymethylfurfural or HMF. It has been identified as the key intermediate compound in the synthesis of liquid biofuels (2,5- dimethylfuran and 2-methylfuran), polymers, pharmaceutical products, etc., constituting a building block in the development of technologies aiming to establish successful biorefineries. However, there are several technical and economic challenges that have delayed its production on an industrial scale. Some of the difficulties are associated with unknown thermodynamic properties and unknown equilibrium-phase compositions during reaction processes, problems in the HMF separation from the aqueous phase due to the presence of byproducts in the extractive phase and additional difficulties related to reusing of the solvent employed. In such context, this project includes: i) an experimental study of the liquid-liquid equilibrium (LLE) of ternary mixtures involved in both the reaction and separation steps for the production of HMF; ii) a thermodynamic modeling of multicomponent phase equilibrium using the Non-Random Two Liquid model (NRTL). Keywords: Liquid-liquid equilibrium, HMF, alcohol, NRTL. (AU)
