SOLUBILITY OF ANTHRACENE IN TERNARY PROPANOL PLUS BUTANOL PLUS 2,2,4-TRIMETHYLPENTANE SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in ter nary 1-propanol + 1-butanol + 2,2,4-trimethylpentane, 1-propanol + 2-b utanol + 2,2,4-trimethylpentane, 2-propanol + 1-butanol + 2,2,4-trimet hylpentane, and 2-propanol + 2-butanol + 2,2,4-trimethylpentane solven t mixtures at 25 degrees C. Nineteen compositions were studied for eac h of the four solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the comb ined NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall averag e absolute deviation of about 0.9%.
