Equilibrium data on ethanol-water-solvent ternaries

Experimental liquid-liquid equilibria of water-ethanol-1-nonanol and water- ethanol-1-decanol systems were investigated at 303.16+/-0.20 K. The reliabi lity of the experimental tie-line data was ascertained by using Othmer-Tobi as and Hand plots. Distribution coefficients (D-i) and separation factors ( S) were evaluated fur the immiscibility region. It is concluded that the so lvents with high boiling point, 1-nonanol and 1-decanol, are suitable separ ating agents for dilute aqueous ethyl alcohol solutions.
