Application of Regular Solution Theory to Discotic Mesophases: Calculation of Phase Diagrams Exhibiting Minima

  • Ralph A. Wheeler
  • Gerald R. Van Hecke


Binary phase diagrams of the discotic nematogenic benzene-hexa-n-alkanoates show minimum azeotrope-like behavior. Regular solution theory is successfully applied to calculate phase diagrams for binary mixtures of four members of this homologous series. Furthermore, an empirical correlation between the regular solution parameters and molar volume ratio of the components is proposed.
