Ternary (liquid + liquid) equilibria for (water + 2-propanol + α-pinene, or β-pinene) mixtures at four temperatures

Ternary (liquid   +   liquid) equilibria date for the (water   +   2-propanol   +   α -pinene, or β -pinene) systems were measured at T   =   (293.15, 298.15, 303.15, and 308.15)   K under atmospheric pressure. The experimental results were correlated using the extended and modified UNIQUAC models. The calculated results obtained from the modified UNIQUAC model successfully represent the experimental tie-line data. The temperature influence on liquid-phase equilibria was studied.
