Experimental solubilities are reported for anthracene in binary mixtures containing ethyl acetate or diethyl adipate withn-hexane,n-heptane,n-octane, cyclohexane, methylcyclohexane and isooctane at 25°C. Results of these measurements, combined with estimates for the excess Gibbs free energies of the binary solvents, are used to evaluate equilibrium constants for presumed anthracene-ethyl acetate and anthracene-diethyl adipate molecular complexes using the Extended Nearly Ideal Binary Solvent model. A single association constant was needed for each assumed complex in order to describe the experimental data to within an average deviation of 2%, though the numerical value did vary with inert hydrocarbon cosolvent. Poor estimates for the binary Gibbs free energies contributed significantly to the equilibrium constant variation.
