The aqueous solubilities of 13 chlorinated derivatives of phenol (3,5-dichlorocatechol, 4,5-dichlorocatechol, 3,4,5-trichlorocatechol, tetrachlorocatechol, vanillin, 5-chlorovanillin, 6-chlorovanillin, 5,6-dichlorovanillin, 3-chlorosyringol, 3,5-dichlorosyringol, trichlorosyringol, 2-chlorosyringaldehyde, and 2,6-dichlorosyringaldehyde) were determined at 25 degrees C, by using a conventional shake-flask, batch contacting method with analysis by high-pressure liquid chromatography with UV detection. The liquid or supercooled liquid solubilities are satisfactorily correlated with the solute’s LeBas molar volume, yielding structure-property relationships that may be useful for predictive purposes.
