ABSTRACT The thermal decomposition analysis of nitrocellulose–nitroglycerine (NC–NG), 3,4‐dinitrofurazanfuroxan (DNTF), and their mixed system with differential scanning calorimetry (DSC), thermogravimetric analysis‐DSC–mass spectroscopy–Fourier transform infrared spectroscopy (TG–DSC–MS–FTIR) coupling technique, in situ FTIR experiments under different experimental conditions was carried out for the investigation interaction mechanism between NC–NG DNTF. results demonstrated that mixture significantly decreased peak temperature DNTF, activation energy final (156.32 kJ mol −1 ) lower than both (163.82 DNTF (177.03 ). On basis gas fragmental products condensed phase changes, triggered thermally process, resulting intensive amount nitrogen oxides which further caused breakage nitro groups

ABSTRACT As a strong oxidizer, ammonium perchlorate (AP) is one of the most paramount raw materials in composite solid propellants (CSP) formulations, and thermal decomposition features AP would directly impact energy release impulsion performance CSP. CuNCN as an example metal carbodiimides explored burn rate modifier for decomposition, given their oxide counterpart belonging to typical modifiers. Our results reveal that as‐prepared can effectively accelerate AP. The additive mixture reduce activation bring down HTD by 84°C. present study highlights on effective application thermally enhanced

The present work aims to stabilize the room temperature allotropic transition of ammonium nitrate (AN) particles utilizing a microencapsulation technique, which involves solvent/non-solvent in nitrocellulose (NC) has been employed as coating agent. SEM micrographs revealed distinct features both pure AN and NC, contrasting with irregular granular surface topography coated particles, demonstrating adherence NC on surface. Structural analysis via infrared spectroscopy (IR) demonstrated successful association slight shifts observed IR bands indicating interfacial interactions. Powder X-ray Diffraction (PXRD) further elucidated structural changes induced by process, revealing that altered crystallization pattern its form. Thermal demonstrates profiles for AN, sample exhibits increase an enthalpy decrease 6 °C, 36%, respectively. Furthermore, presence alters intermolecular forces within composite system, leading reduction melting ∼39% compared AN. thermal decomposition shows two-step thermolysis process significant released heat about 78% accompanied activation barrier thermolysis, stabilized reactivity AN-NC particles. These findings highlight synergistic effect contributed reactive stabilization proving potential application NC-coated strategically advantageous oxidizer solid propellant formulations.

In the pursuit of advancing imidazolium-based energetic ionic liquids (EILs), current study is devoted to synthesis and characterization 1,3-dibutyl-imidazolium azide ([BBIm][N3]), as a novel member in this class. The chemical structure EIL was rigorously characterized confirmed using FTIR spectroscopy, 1D, 2D-NMR analyses. thermal behavior assessment conducted through DSC TGA experiments. analysis revealed an endothermic glass transition at Tg=-61 °C, followed by exothermic degradation event Tonset=311 °C. Similarly, thermograms exhibited one-stage decomposition process resulting 100% mass loss sample. Furthermore, short-term stability investigated combining non-isothermal data with TAS, it-KAS, VYA/CE isoconversional kinetic approaches. Consequently, Arrhenius parameters (Ea=154 kJ∙mol-1, Log(A/s-1))=11.8) most probable reaction model g(α) were determined. observed high temperatures significantly elevated activation energy affirm enhanced modified EIL. These findings that [BBIm][N3] can be promising candidate for advanced material application.
