“…Nevertheless, it has been verified that this top peak does not represent the point of complete dissolution but defines, more exactly, the point where the energy exchange between the sample and thermocouples is at a maximum [28,29]. Some other studies have adopted numerical post-experiment methodologies based on factors influencing the shape of the thermogram to identify T liquidus [30,31]. Still that all these procedures are under development and limited by several factors [28].…”

Four binary mixtures with potential for stabilizing energetic materials have been investigated. The phase diagrams of N-(2-methoxyethyl)-p-nitroaniline þ diphenylamine, N-(2-methoxyethyl)-p-nitroaniline þ N-(2-acetoxyethyl)-p-nitroaniline, N-(2-methoxyethyl)-p-nitroaniline þ 2-nitrodiphenylamine, and N-(2methoxyethyl)-p-nitroaniline þ 1,3-diethyl-1,3-diphenylurea have been determined by differential scanning calorimetry. All systems display a simple eutectic behavior. Consistency tests have been applied to inspect the quality of the SLE data, showing very satisfactory quality factors. The SLE data have also been correlated by Wilson and NRTL models. The employed equations calculated the equilibrium temperatures with a root mean square deviations varying from 1.37 to 2.29 K. These models have been applied to compute the excess thermodynamic functions as well, giving highly comparable values for a further qualitative and quantitative analysis. The results show a positive deviation from ideality for all the investigated systems due to the dominant effect of the self-association molecules. The XRD studies revealed the existence of weak interactions between the components in the formed eutectics and suggested that they are mechanical systems.

“…This problem can be overcome by use of the fractional transformation method and for solid liquid transition is defined as the fraction of mixture that is liquefied. [6] Mathematically, it is measured from the ratio of heat generated at a time interval to total heat released at the eutectic temperature:…”

Binary phase diagrams for two mixtures of methylnitramine (1) + 2,4-dinitro-2,4-diazapentane (2) (eutectic temperature T E = 285.1 K, eutectic composition x 1 = 0.565) and methylnitramine (1) + 2,4-dinitro-2,4-diazahexane (2) (eutectic temperature T E = 280.3 K, eutectic composition x 1 = 0.653) were studied using differential scanning calorimetries (DSC). For both systems simple eutectic behavior was observed. The eutectic compositions were also determined using Gray's model and the fractional transformation method.

“…Differential scanning calorimetry (DSC) is a sensitive technique for the detection and evaluation of phase transitions and has been successfully used to study the behavior of (SLE) [3,[10][11][12][13][14][15]. Among the main advantages attributed to this technique, we can cite the use of small amounts of sample (0.1-20 mg), relatively short time of analysis, no special care required with respect the physical state of the sample, and any liquid or solid material can be analyzed with the possibility of application in a wide temperature range with various heating rate programs [16].…”
