Solubility of Anthracene in Ternary 2,2,4-Trimethylpentane + Propanol + 1-Pentanol and 2,2,4-Trimethylpentane + Butanol + 1-Pentanol Mixtures

Abstract

Experimental solubilities are reported for anthracene dissolved in ternary 2,2,4-trimethylpentane + 1-propanol + 1-pentanol, 2,2,4-trimethylpentane + 2-propanol + 1-pentanol, 2,2,4-trimethylpentane + 1-butanol + 1-pentanol, and 2,2,4-trimethylpentane + 2-butanol + 1-pentanol solvent mixtures at 298.15 K and atmospheric pressure. For each of the four ternary solvent systems, 19 compositions were studied. Results of these measurements are used to test the predictive ability of the ternary solvent form of the Jouyban−Acree model (also referred to in the literature as the combined NIBS/Redlich–Kister model). Computations showed that the model predicted the observed solubility behavior to within an overall average absolute relative percentage deviation of about 1.5.
