Abstract
Experimental solubilities are reported for anthracene dissolved in binary solvent mixtures containing 1-chlorobutane with n-hexane, n-heptane, n-octane, cyclohexane, methylcyclohexane and isooctane at 25°C. Results of these measurements, combined with estimates for the excess Gibbs free energy of the binary solvents, are used to evaluate the equilibrium constant for a presumed anthracene-chlorobutane molecular complex from the Extended Nearly Ideal Binary Solvent model. A single equilibrium constant was needed to describe the experimental data to within an average deviation of about 0.7%. The calculated association constant varied slightly with inert hydrocarbon cosolvent, the values ranging from K ϕ AC =2.5 for isooctane to K ϕ AC =6.0 for the cyclohexane cosolvent.
