Abstract

Liquid-Liquid equilibrium data for the (water + Lactic acid + 2-ethy-1-hexanol) ternary system in T=298.2K and P=1atm were determined and tie- lines related to equilibrium data has been drawn in the phases diagram . The reliability of the experimental tie-line data for this system was as confirmed by using the Hand and Othmer –Tobias correlations. The tie-line data were correlated by means of the UNIQUAC equation for this ternary system , The average root mean square deviation between the observed and calculated mass fractions was 0.66%. A comparison of the extracting capabilities of this solvent by 1-octanol was made with respect to distribution coefficients and separation factors bases. The results show that extraction of lactic acid from aqueous solutions by 2-Ethyl-1-hexanol is possible and 2-Ethyl-1-hexanol is more appropriate than the other octanol isomer.
