Solubility of Anthracene in Ternary Dibutyl Ether + Alcohol + Cyclohexane Solvent Mixtures

Abstract

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°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 NIMS/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%.

“…[19][20][21] In all fairness, we should mention that the earlier studies covered much smaller 4-8-fold ranges in anthracene mole fraction solubilities. One should not expect the same level of predictive accuracy in systems that cover significantly larger solubility ranges.…”
