Solubility of Anthracene in Ternary 2-Butoxyethanol + Propanol + Butanol Solvent Mixtures

Experimental solubilities are reported for anthracene dissolved in ternary 2-butoxyethanol + 1-propanol + 1-butanol, 2-butoxyethanol + 1-propanol + 2-butanol, 2-butoxyethanol + 2-propanol + 1-butanol, and 2-butoxyethanol + 2-propanol + 2-butanol solvent mixtures at 25 °C and atmospheric pressure. For each of the four solvent systems, 19 compositions were studied. 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%.
