Experimental solubilities are reported for anthracene dissolved in ternary methyl tert-butyl ether + 1-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 1-butanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-butanol + 2,2,4-trimethylpentane, and methyl tert-butyl ether + 2-methyl-1-propanol + 2,2,4-trimethylpentane 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 NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.7%, which is comparable to the experimental uncertainty of +/-1.5%.
