SOLUBILITY OF HEXANE, PHENANTHRENE, CHLOROBENZENE, AND P-DICHLOROBENZENE IN AQUEOUS-ELECTROLYTE SOLUTIONS

The solubilities of hexane, phenanthrene, chlorobenzene, and p-dichlorobenzene were determined in water and in aqueous solutions of NaCl, Na2SO4, KCl, NaBr, and NH4Cl at 25 °C. The salting-out effect is well represented by the Setschenow equation. A correlation based on the McDevit-Long theory is presented which gives the salting-out factor as a function of organic solute molar volume and an empirical constant characteristic of the electrolyte. The data for the chlorobenzenes suggest that the correlation may be applicable to halogenated hydrocarbons. © 1979, American Chemical Society. All rights reserved.
