ABSTRAC The purpose of this work is to study the equilibrium on the extraction of lactic acid in aqueous solution with pure solvents of petroleum ether and kerosene. The study of the effect of different solvent on the extraction equilibrium of lactic acid in aqueous solution was carried out at ambient temperature. The parameter studied in this work was the total concentration of lactic acid in the aqueous phase. The result of this work is compared to the equilibrium data of lactic acid extraction using xylene obtained from the literature. From the three different solvents, kerosene is the best solvent to extract lactic acid from aqueous solution. The distribution coefficient increases with the increase of the total concentration of lactic acid in the aqueous phase for the extraction using all pure solvents studied in this work. The study of the effect of temperature on the extraction equilibrium showed that the higher the extraction temperature the lower the distribution coefficient of the extraction.
