The Co/Cu/Ni/Fe salts of 3-nitro-1,2,4-triazol-5-one (NTO) and 2,4,6-trinitroanilino benzoic acid (TABA) were prepared and characterized during this work. All the salts exhibited exothermic decomposition in DSC. The FT-IR spectra of the gaseous products evolved during TGA of NTO salts indicated the release of NO2 and cleavage of NTO ring during the course of decomposition. Thermal decomposition of TABA salts also produced NO2 on decomposition. The transition metal salts enhanced the burning rates of AP-HTPB composite propellant evaluated during this work. The best catalytic effect was obtained with Fe-NTO salt which increased the burning rate to the extent of approximately 80% as well as brought down the pressure index (n) to 0.18 (2-9MPa).
在本研究工作中制备并表征了3-硝基-1,2,4-三唑-5-酮（NTO）和2,4,6-三硝基苯胺基苯甲酸（TABA）的Co/Cu/Ni/Fe盐。所有盐在差示扫描量热法（DSC）中均表现出放热分解。NTO盐热重分析（TGA）过程中逸出的气态产物的傅里叶变换红外光谱（FT-IR）表明，分解过程中释放出NO₂且NTO环发生裂解。TABA盐的热分解在分解时也产生NO₂。在本研究工作中评估发现，过渡金属盐提高了端羟基聚丁二烯（AP-HTPB）复合推进剂的燃烧速率。Fe-NTO盐具有最佳催化效果，它将燃烧速率提高到约80%的程度，并将压力指数（n）降至0.18（2 - 9MPa）。
