Abstract: TOPOLOGICAL ANALYSIS OF THE GM FUNCTION IN LIQUID-LIQUID EQUILIBRIUM CORRELATION DATA FOR TERNARY AND BINARY SYSTEMS (version 2.1). A single and very easy to use Graphical User Interface (GMcal_TieLinesLL) based on the topological information contained in the Gibbs energy of mixing function has been developed in MatLab, as a friendly tool to check the coherency of the parameters obtained in a correlation procedure of binary and ternary LLE data. Thus, the analysis of the GM/RT surface, the GM/RT for the binaries and the GM/RT in planes containing the tie lines should be necessary to validate the obtained parameters for the different models for correlating phase equilibrium data. NRTL and UNIQUAC models are the ones that can initially be used (by defect) to calculate the GExcess. However, any other alternative model could be easily implemented (see user instructions pdf file). The version 2.1 of this friendly tool also allows on the one hand, the analysis of the Hessian Matrix determinant (s), the spinodal curve (s=0) and the Plait Point location for LLE ternary systems, using additionally the d and d* matrix determinants, which have to be also equal to zero. On the other hand, the analysis of LLE binary systems at different temperatures, including the location, if there exits, of the Critical Solution Temperature (UCST, LCST or Closed Misciblity Loops).
