Abstract | Full Text

Experimental liquid-liquid equilibria of water-ethanol-1-nonanol and water-ethanol-1-decanol systems were investigated at 303.16± 0.20 K. The reliability of the experimental tie-line data was ascertained by using Othmer-Tobias and Hand plots. Distribution coefficients (Di) and separation factors (S) were evaluated for the immiscibility region. It is concluded that the solvents with high boiling point, 1-nonanol and 1-decanol, are suitable separating agents for dilute aqueous ethyl alcohol solutions.
