Abstract

The present work reports liquid-liquid equilibrium data for systems containing water + 5-hydroxymethylfurfural + [1-butanol, 2-butanol or 2-pentanol] at T = 298.2 K and atmospheric pressure (similar to 0.1 MPa), determined by refractometry and density measurements. The results were evaluated by calculation of the overall mass balance, resulting in overall relative deviations lower than 1.05%. Experimental data were correlated with the NRTL model to calculate the activity coefficient. The average root mean square deviation was equal to 0.65% for all systems. Cloud points, tie lines, partition coefficients and selectivities indicated that 2-pentanol is better than the other studied solvents for 5-hydroxymethylfurfural recovery from water.
