Solubility of anthracene in ternary (propanol plus heptane plus cyclohexane) and (butanol plus heptane plus cyclohexane) solvent mixtures

Experimental solubilities are reported for anthracene dissolved in ternary (1-propanol + heptane + cyclohexane), (2-propanol + heptane + cyclohexane), (1-butanol + heptane + cyclohexane), and (2-butanol + heptane + cyclohexane) solvent mixtures at T = 298.15 K. 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 NIBS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.3 per cent. (C) 1999 Academic Press.
