Solubility of anthracene in binary alcohol plus methyl acetate solvent mixtures at 298.2 K

Experimental solubilities are reported for anthracene dissolved in eight binary alcohol + methyl acetate solvent mixtures at 25 degreesC. The alcohol cosolvents studied were l-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 1-pentanol, 2-pentanol, and 3-methyl-1-butanol. Results of these measurements are used to test two mathematical representations based upon the combined nearly ideal binary solvent (NIBS)/Redlich-Kister and modified Wilson equations. For the eight systems studied, the combined NIBS/Redlich-Kister equation was found to provide the better mathematical representation of the experimental data, with overall average absolute deviations between measured and calculated values being approximately +/-0.5%. Considerably larger deviations were noted in the case of the modified Wilson equation.
