SOLUBILITY OF ANTHRACENE IN BINARY ALCOHOL PLUS 2-PENTANOL AND ALCOHOL PLUS 4-METHYL-2-PENTANOL SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in 16 binary mixtures containing either 2-pentanol or 4-methyl-2-pentanol wi th 1-propanol, 2-propanol, 1-butanol, 2-butanol, 1-pentanol, 1-octanol , 2-methyl-1-propanol and 3-methyl-1-butanol at 25 degrees C. Results of these measurements are used to test two mathematical representation s based upon the combined nearly ideal binary solvent (NIBS)/Redlich-K ister equation and modified Wilson model. For the 16 systems studied, both equations were found to provide an accurate mathematical represen tation of the experimental data, with an overall average absolute devi ation between measured and calculated values being 0.3% and 0.5% for t he combined NIBS/Redlich-Kister and modified Wilson equations, respect ively.
