SOLUBILITY OF ANTHRACENE IN BINARY ALKANE-ISOPROPOXYETHANOL SOLVENT MIXTURES AT 298.2 K(2)

Experimental solubilities are reported for anthracene dissolved in sev en binary alkane + 2-isopropoxyethanol solvent mixtures at 25 degrees C. The alkane cosolvents studied were hexane, heptane, octane, cyclohe xane, methylcyclohexane, 2, 2, 4-trimethylpentane and tert-butylcycloh exane (also called (1,1-dimethylethyl)cyclohexane). Results of these m easurements are used to lest two mathematical representations based up on the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister and Modified Wilson equations. For the seven systems studied, both equatio ns were found to provide an accurate mathematical representation of th e experimental data, with an overall average absolute deviation betwee n measured and calculated values being 0.5% and 0.7% for the Combined NIBS/Redlich-Kister and Modified Wilson equations, respectively.
