Ternary and Binary LLE Measurements for Solvent (4-Methyl-2-pentanone and 2-Methyl-2-butanol) + Furfural plus Water between 298 and 401 K
Two solvents, 4-methyl-2-pentanone (methyl isobutyl ketone, MIBK) and 2-methyl-2-butanol (tertpentanol, TAA), were tested and compared according to their performance in furfural extraction from aqueous solutions. Two new experimental apparatus were built and novel liquid liquid equilibrium of ternary systems consisting of solvent, furfural, and water were measured between 298 and 401 K having boiling point pressure up to 4 bar. In addition, liquid liquid equilibrium of binary systems were measured between 298 and 352 K at atmospheric pressure. Measurements were modeled with UNIQUAC activity coefficient model and its binary interaction parameters were presented together with the measured data. The suitability of solvent for industrial use was discussed with selectivity and distribution factors.
