The aqueous solubilities and octanol-water partition coefficients at 25 degrees C of veratrole (1,2-dimethoxybenzene), three chlorinated veratroles, and nine chlorinated anisoles (methoxybenzenes) were measured by a conventional shake-flask, batch-contacting method. The data indicate that both solubilities and octanol-water partition coefficients are well correlated with LeBas molar volume, yielding structure-property relationships which may be useful for predictive purposes. Correlation of supercooled liquid solubilities and octanol-water partition coefficients of a series of phenolic compounds suggests that in aqueous solution the chloroveratroles and chloroanisoles behave similarly to nonpolar aromatic compounds such as the chlorobenzenes and differently from the related chlorophenolic substances.
