Abstract
The binodal curves and liquid−liquid equilibrium data are presented for pseudoternary mixtures of n-hexane + toluene + (N-methyl-2-pyrrolidinone + a solvent). The solvents used in this investigation were glycerol, monoethylene glycol, diethylene glycol, triethylene glycol, and water. The results are discussed in terms of the separation selectivity of related systems, and the binodal curve data were fitted to the Hlavaty equation, the β-density function, and the logarithmic-γ function. The binodal curves showed good correlation with these equations. The NRTL and UNIQUAC equations were used to correlate the experimental tie-lines, which showed reasonable correlation.
