Abstract
Experimental solubilities are reported for anthracene in binary solvent mixtures containing toluene with n-hexane, cyclohexane, n-heptane, methylcyclohexane, n-octane, cyc-looctane and isooctane at 25°C. Results of these measurements are used to test five predictive expressions derived from the Nearly Ideal Binary Solvent (NIBS) model. The most successful equation in terms of goodness of fit involved a surface fraction average of the excess partial molar Gibbs free energy of the solute relative to Raoult's law and predicted the experimental anthracene solubilities in the 7 systems studied to within an average absolute deviation of 4.5%.Keywords
