Phase Diagrams and Thermodynamic Properties of Binary and Ternary Systems Based on Nitroaromatic Compounds

Abstract

The phase diagram data of 226 binary organic systems based on nitroaromatic compounds were critically evaluated with the aid of a computer-coupled thermodynamic/phase diagram analysis. The results of this analysis include the excess Gibbs energies of all solution phases as well as the Gibbs energies of fusion and formation of intermediate compounds. These quantities were used to calculate a best phase diagram for each system. The phase diagrams of seven ternary systems were calculated from the evaluated thermodynamic data of the binary subsystems with the use of the Kohler interpolative model and compared with the experimental diagrams.
