Ternary (liquid plus liquid) equilibria for (water+2-propanol + alpha-pinene, or beta-pinene) mixtures at four temperatures
Ternary (liquid + liquid) equilibria date for the (water + 2-propanol + alpha-pinene, or beta-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.
