Experimental and correlated tie-line data for aqueous mixtures of Formic acid with ۲-ethyl-۱-hexanol at T=۲۹۸.۲ K.

Liquid–liquid phase equilibria (LLE) for the system of water/formic acid/۲-ethyl-۱-hexanol were investigated experimentally at temperature of ۲۹۸.۱۵ K.Atype ۲ liquid–liquid phase diagram was obtained for this ternary system. These results were correlated simultaneously by the UNIQUAC model. The values of the interaction parameters between each pair of components in the system were obtained forthe UNIQUAC model using the experimental results. The root mean square deviation (RMSD) between the observed and calculated masspercents was ۰.۴۸۸۵%. The mutual solubility of ۲-ethyl-۱-hexanol and water was also investigated by the addition of formic acid at temperature۲۹۸.۱۵ K.
