Solubility of anthracene in ternary dibutyl ether plus alcohol plus cyclohexane solvent mixtures

Experimental solubilities are reported for anthracene dissolved in ternary dibutyl ether + 1-propanol + cyclohexane, dibutyl ether + 2-propanol + cyclohexane, dibutyl ether + 1-butanol + cyclohexane, dibutyl ether + 2-butanol + cyclohexane, and dibutyl ether + 2-methyl-1-propanol + cyclohexane solvent mixtures at 25 degrees C and atmospheric pressure. Nineteen compositions were studied for each of the five solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the combined NIM/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.5%, which is comparable to the experimental uncertainty of +/-1.5%.
