    Abstract

    Solubility was reported for 2,6-diamino-3,5-dinitropyridine in N,N-dimethylformamide at (304.15 to 357.15) K, dimethylsulfoxide at (304.15 to 339.15) K, ethanol at (305.15 to 340.15) K, methanol at (293.15 to 339.15) K, and 2,5-dihydroxyterephthalic acid in N,N-dimethylformamide at (298.15 to 370.15) K, dimethylsulfoxide at (293.15 to 342.15) K, N,N-dimethylacetamide at (318.15 to 355.55) K, and acetic acid at (320.15 to 369.15) K. Results of these measurements are fitted with the combined binary solvent Margules equation. For the systems studied, the Margules equation is found to provide reasonable mathematical representation, with the average deviations between experimental values and calculated ones being on the order of ± 1.0 % and ± 0.2 % or less. Furthermore, the coupler parameters of the Margules equation (A21, A12) and the enthalpy of fusion (ΔfusH) were obtained by the Levenberg−Marquardt method and Global Optimization method.
