“…They act by removing nitrogen oxides formed during the autocatalytic decomposition. By reacting with nitrogen oxides, these stabilizers are converted to a range of nitrosamines and nitroamines [4][5][6][7][8][9]. The reactions of these stabilizing agents are complex and many successive products of the primary stabilizer, also named daughter products, are generated.…”

“…The thermodynamic properties and structural details of these mixtures have received much less attention. Recent studies of their solid-liquid equilibria are significant [9,13,14], providing model systems for detailed investigation of several parameters controlling the stability and subsequent behaviour of energetic materials. As such, these systems will be certainly used as model systems for details investigation of several parameters which control the stability and subsequently decide about the behaviour of energetic materials.…”

“…Recently, it has been reported that differential scanning calorimetry (DSC) technique allows more accurate and rapid characterisation of any kind of phase change [9,[15][16][17][18][19]. Thus, it seemed interesting to use the DSC technique for the determination of SLE of complex systems including the stabilizers diphenylamine, ethyl centralite, methyl centralite and their derivatives.…”

“…Chemical structures of the compounds studied are given in Fig. 1 In previous works, our research group has studied the thermodynamic properties and (solid + liquid) equilibria of several polyaromatics mixtures [9,13,14,20]. In the present survey, SLE data for four binary systems of diphenylamine (1) + N-ethyl-4-nitroaniline (2), ethyl centralite (1) + N-ethyl-4-nitroaniline (2), methyl centralite (1) + N-ethyl-4-nitroaniline (2) and N-(2-acetoxyethyl)-p-nitroaniline (1) + N-ethyl-4-nitroaniline (2) were measured using DSC.…”

“…Following our systematic study of the thermodynamic properties of organic mixtures [1,2], it seemed interesting to test the application of DSC to the determination of SLE of complex system including N-(2-acetoxyethyl)-p-nitroaniline and N-ethyle-4-nitrooaniline (2). These components are used as stabilizers of nitrocellulose.…”

Abstract. The nitrocellulose based materials are degraded in a natural way during their storage; the processes of degradation are accelerated when the temperature or the humidity increases. To prevent this decomposition, these materials include in their composition stabilising agents which retain the nitro groups and avoid the autocatalytic degradation of nitrocellulose. The aim of the present work is to improve our understanding of the basic mechanisms of the degradation of the nitrocellulose based materials and the way in which their stabilization evolves. Solid-liquid phase equilibrium for the binary system of (N-(2-acetoxyethyl)-p-nitroaniline (1) + Nethyle-4-nitrooaniline (2)) is determined using DSC technique. The experimental results were correlated using Wilson and UNIQUAC models. As results, the system studied presents a simple eutectic, where the components are not miscible in the solid phase. Important deviations between experimental and predicted values are observed in the case of ideal model. These deviations can be attributed to the complexity of our system and principally to the presence of intermolecular effects. The best description of SLE was given by the two parameters UNIQUAC.

In this paper, the compatibility of nitrocellulose (NC) with some aniline‐based stabilizers was studied in order to detect any interaction between these materials. Both thermal techniques [differential scanning calorimetry (DSC) and vacuum stability test (VST)], and supplementary non‐thermal techniques [Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD) and densimetry] were used. The thermal and non‐thermal measurements showed that NC was highly compatible with N‐(2‐methoxyethyl)‐p‐nitroaniline (MENA) and diphenylamine (DPA), while a degree of incompatibility is indicated for N‐(2‐acetoxymethyl)‐p‐nitroaniline (ANA). The compatibility of the different mixtures was further probed by the kinetic investigation, and the activation energy and the pre‐exponential factors were computed. A detailed discussion and comparison of the compatibility results from all the methods are made.
