Abstract: The experimental liquid-liquid equilibria of a water-ethanol-1-dodecanol system were investigated at temperatures of 298.16\pm0.20, 303.16\pm0.20 and 308.16\pm0.20 K. The reliability of experimental tie-line data was ascertained by using Othmer-Tobias and Hand plots. Distribution coefficients (D_i) and separation factors (S) were evaluated for the immiscibility region. It was concluded that the high boiling solvent 1-dodecanol, is a possible separating agent for dilute aqueous ethyl alcohol solutions.
Keywords: ethanol, 1-dodecanol, liquid-liquid extraction
