Model to Describe the Binodal Curve on a Type 1 Ternary Phase Diagram

Abstract

A regression curve based on a Weibull distribution model is generated to describe the binodal curve on a three component liquid-liquid ternary phase diagram. The methodology involves transforming the experimental phase partitioning data points of each mixture from the ternary phase diagram to equivalent Cartesian coordinates. The regression curve is then generated, and the regression curve becomes the Weibull-derived binodal curve by superimposing the regression curve onto the original ternary phase diagram. A total of seven regression curves for seven ternary mixtures are generated in this study. From the regression analysis, the resulting
