Distribution coefficient data ate presented for phenol at 25°C between water and nine mixed solvents. The binary solvent mixtures were n‐octane with n‐hexanol‐l, n‐octanol‐l and n‐decanol‐l; n‐octanol‐l with benzene carbontetrachloride, cyclo‐hexane, kerosene and butyl acetate; and n‐butyl acetate with benzene. All alcohol mixtures exhibited a positive deviation from linearity in distribution co‐efficient, maxima being obtained for mixtures of n‐octanol‐l with n‐butyl acetate and benzene. The data are correlated empirically and the nature of the chemical associations discussed. Practical implications are that esteralcohol mixtures may be the preferred solvents for phenol extraction from water since these mixtures have distribution coefficients significantly greater than either pure solvent.
