摘要：

In order to investigate the use of toluene for separating phenol in aqueous phenol solution, the liquid liquid equilibria for the ternary phenol + water+ toluene system and constituent binary phenol+water and water+toluene systems are measured between 298.15 and 343.15 K. The distribution coefficients of phenol become larger as the temperature becomes low. The extraction ability of toluene is considered to be similar to that of benzene used in Podobielniak dephenolizing equipment. The ternary liquid-liquid equilibria predicted by the SILS equation using binary parameters agree with the observed ones for three components within the absolute arithmetic absolute deviations of 0.014 mole fraction.
