Abstract
Partial solubility parameters of chlorobenzene and chlorophenol compounds at equilibrium distribution in two immiscible phases such as soil-water system were studied. An integral distribution equilibrium equation is derived from the concept of partial solubility parameters and Flory-Hungins equation. Twelve chlorobenzenes and nineteen chlorophenols were employed in this study and their partial solubility parameters including dispersion ( δ (d) ), and polar van der Waals ( δ (p)), as well as their electron acceptor and donor solubility parameters ( δ (a) and δ (b) ) were calculated. Hildebrand's solubility parameter ( δ ) of the compounds was also obtained by using boiling point and formula. HPLC was performed by octadecyl-bonded phase as the stationary phase with methanol or acetonitrile as the mobile phase to determine the capacity factor k' of all compounds for the calculation of δ (a) and δ (b).
