SOLUBILITY OF ANTHRACENE IN BINARY ALKANE PLUS 2-BUTANOL SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in six binary mixtures containing e-butanol with n-hexane, n-heptane, n-octa ne, cyclohexane, methylcyclohexane, and 2,2,4-trimethylpentane at 25 d egrees C. Results of these measurements are used to test two mathemati cal representations based upon the combined nearly ideal binary solven t (NIBS)/Redlich-Kister equation and modified Wilson model. For the sy stems studied, the combined NIBS/Redlich-Kister and modified Wilson eq uations were found to provide very reasonable mathematical representat ions, with deviations between experimental and back-calculated values on the order of +/-1.5% or less.
