(Liquid + liquid) equilibria in ternary aqueous mixture of Formic acid with ۱-Hexanol at T = ۲۹۸.۲ K.

Ternary equilibrium data for the mixtures of {water + Formric acid + ۱-Hexanol} were determined at T = ۲۹۸.۲ K and atmospheric pressure. Solubility data were determined by the cloud-point titration method. In order to obtain the tie-line data, the concentration of each phase was determined by acidimetric titration, the Karl–Fischer technique. The experimental tie-line data were correlated using the UNIQUAC model. The reliability of the experimental data was determined through the Othmer–Tobias and bachman plot. Distribution coefficients and separation factors were evaluated over the immiscibility regions.
