The distributions of aniline, 4-methylaniline, 3,4-dimethylaniline, and 2,4,5-trimethylaniline between octanol and water were determined as a function of pH and KCl concentration in the aqueous phase. The data were interpreted in terms of a multicomponent equilibrium model with anilinium in the water-saturated octanol as free ions and ion pairs. The implications of these results to the use of the octanol-water reference system for organic bases and to the sorbent-water distribution of organic bases in the environment is discussed.
