                     The UNIQUAC equation can be used to estimate activity coefficients and liquid
                   compositions for multicomponent liquid-liquid systems. The UNIFAC method can be
                   used to estimate UNIQUAC parameters when experimental data are not available, see
                   Section 8.16.5.
                     It must be emphasised that extreme caution needs to be exercised when using predicted
                   values for liquid activity coefficients in design calculations.
