Phase equilibria for the ternary liquid systems of (water plus tetrahydrofurfuryl alcohol plus cyclic solvent) at 298.2 K

Abstract

(Liquid + liquid) equilibrium data of the solubility (binodal) curves and tie-line end compositions are presented for mixtures of [water (1) + tetrahydrofurfuryl alcohol (2) + cyclohexane or cyclohexanol or cyclohexyl acetate or chlorobenzene (3)] at T = 298.2 K and P = 101.3 kPa. Among the studied C6 ring-containing organic solvents, cyclohexanol and cyclohexyl acetate show the best extraction efficiency for tetrahydrofurfuryl alcohol, giving the largest distribution coefficients. The tie lines have been estimated in terms of the UNIFAC-original model. The model matches the distribution data of the studied ternaries moderately accurately.
