摘要：

A simple correlation to fit type I liquid-liquid equilibria (LLE) data is presented. Like the Hand plot (J. Phys. Chem. 1930, 24, 1961) and the correlation by Rod (Chem. Eng. J. 1976, 11, 105), it correlates the distribution;coefficients for e three components as a function of a scaling parameter that is a measure of the distance along the binodal from the binary end point to the plait point. It can be used to estimate the composition of the plait point and to interpolate and extrapolate data. It is also useful for estimating distribution coefficients for additional trace components (impurities that may build up in recycle around an extraction operation) when there is limited data. This correlation provides a fit that is comparable to or better than the fit obtained using the liquid activity coefficient models.
