Phase Equilibrium of Water + Formic Acid + ۱-Heptanol ternary Liquid Systems at T=۲۹۸.۱۵ K.

Liquid–liquid equilibrium data of the solubility (binodal) curves and tie-line end compositions are presented for mixtures of [water (۱) + formic acid (۲) + ۱-Heptanol (۳)] at ۲۹۸.۱۵K and ۱۰۱.۳±۰.۷ kPa UNIQUAC model. The reliability of the model has been analyzed against the LLE data with respect to the distribution ratio and separation factor. The root mean square deviation (RMSD) between the observed and calculated mass percents was ۰.۴۸۸۵%.
