Solubility of Anthracene in Ternary Propanol + 2,2,4-Trimethylpentane + Cyclohexane and Butanol + 2,2,4-Trimethylpentane + Cyclohexane Solvent Mixtures

Abstract

Experimental solubilities are reported for anthracene dissolved in ternary 1-propanol + 2,2,4-trimethylpentane + cyclohexane, 2-propanol + 2,2,4-trimethylpentane + cyclohexane, 1-butanol + 2,2,4-trimethylpentane + cyclohexane, and 2-butanol + 2,2,4-trimethylpentane + cyclohexane solvent mixtures at 25°C. Nineteen compositions were studied for each of the four solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the 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%.

“…In the case of structurally similar drug molecules the numerical values of the S i coefficients were found to be nearly constant in a given binary solvent mixture. 10 For a ternary solvent system, the mathematical representation takes the form of Recent studies have shown that eq 3 provides reasonably accurate predictions for anthracene solubilities in ternary two alkane + alcohol 14,15 and alkane + two alcohol [16][17][18] solvent mixtures. Such systems exhibit fairly large deviations from solution ideality arising from the self-association of each alcohol cosolvent and, in mixtures containing two alcohol cosolvents, from the formation of heterogeneous hydrogen-bonded chains between dissimilar alcohol molecules.…”
