| Abstract: | The effect of each component of mixed solvents consisting of tertiary amine,alcohol or ketone and kerosene on the extraction of carboxylic acids from water solution is discussed. The isothermal extraction equilibrium equation and the relationship between the temperature and the equilibrium concentrations of carboxylic acid in the organic phase and that in the aqueous phase are inferred. The data of the liquid -liquid equilibrium is related. |

| Keywords: | ternary solvents carboxylic acids extrating mechanism equilibrium equation |
