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

Experimental solubilities are reported for anthracene dissolved in ter nary 1-propanol + 2,2,4-trimethylpentane + cyclohexane, 2-propanol + 2 ,2,4-trimethylpentane + cyclohexane, 1-butanol + 2,2,4-trimethylpentan e f cyclohexane, and 2-butanol + 2,2,4-trimethylpentane + cyclohexane solvent mixtures at 25 degrees C. Nineteen compositions were studied f or each of the four solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of th e combined NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.6%.
