In this link: http:\/\/rua.ua.es\/dspace\/handle\/10045\/51725<\/a>, it is possible to acces to a very easy to use Graphical User Interface (GMcal_TieLinesLL v.2.3<\/a>)<\/strong> based on the topological information contained in the Gibbs energy of mixing function, that has been developed for binary and ternary LLE systems, as a friendly tool to check the coherence of the parameters obtained in a correlation data procedure (the NRTL and UNIQUAC models are included by defect, however any other GExcess<\/sup>(L)\/RT model could be easily implemented).<\/p>\n

\"\"<\/a><\/p>\n

The analysis of the GM<\/sup>(L)\/RT surface in the whole range of composition, the GM<\/sup>(L)\/RT for the binaries subsystems and the GM<\/sup>(L)\/RT curves in planes containing the liquid-liquid tie lines should be necessary to validate the obtained parameters for the different models for correlating phase equlibrium data. This simple analysis could be used by authors and journals in order to guarantee the adequate prediction of equilibrium. In addition, restrictions on NRTL binary parameters have been used in the correlation procedure to guarantee the adequate prediction of the total or partial miscibility behavior of the binary subsystems.<\/p>\n

The NEW VERSION 2.3 of this friendly tool also allows the analysis of the Hessian Matrix determinant (\u03c3), the spinodal curve<\/strong><\/em> (\u03c3=0) and the Plait Point location<\/em><\/strong> for LLE ternary systems, using additionally the \u03b4 and \u03b4* matrix determinants, which have to be also equal to zero and additionally the miscibility boundaries<\/strong><\/em> (for \u03b1ij<\/sub> values different from 0.2). The analysis of LLE binary systems at different temperatures<\/strong><\/em> is also possible, including the location, if there exits, of the Critical Solution Temperature (UCST, LCST or Closed Misciblity Loops).<\/p>\n
