Semiequilibrium dialysis measurements have been made to determine solubilization equilibrium constants and activity coefficients of mono- and dichlorophenols in aqueous solutions of hexadecylpyridinium chloride (CPC) at 25{degree}C. Solubilization equilibrium constants (which relate the concentration of solubilizate in the micelle to the concentration of free organic in the bulk solution) are well correlated by the expression K = K{sub 0}(1 {minus} BX){sup 2}, where B is an empirical constant, K{sub 0} is the limiting value of the solubilization constant, and X is the mole fraction of the phenol present in the surfactant micelles.
