Neutralizing agents including tert-butanol and aniline have been tested for separating the mixtures and their applicabilities were discussed. We found that aniline could be a potential neutralizing agent by the fact that it forms complexs with both m-chlorophenol and p-chlorophenol. Consequently,we further investigated the solid-liquid phase behavior for the ternary system of aniline +m-chlorophenol +p-chlorophenol. This ternary phase diagram provided us useful information for finding a feasible separati- on procedure and favorable operation conditions. The separating process was disscussed by duffferent initial composition of m-chlorophenol +p-chlorophenol mixture.
