UNIQUAC, which stands for Universal Quasi-Chemical, is a thermodynamic model used to predict the phase behavior of multicomponent mixtures. It is particularly useful in the field of chemical engineering for modeling liquid-liquid and liquid-vapor equilibria. The model is based on the concept of activity coefficients, which represent the effective concentration of a species in a mixture relative to an ideal solution.
