摘要
合成了2,6-二氨基-3,5-二硝基吡啶-1-氧化物(ANPyO)Cr(Ⅲ)和Zn(Ⅱ)两种过渡金属配合物。用FT-IR光谱和元素分析表征了这两个配合物。用DSC和TG-DTG研究了这两种配合物对RDX、HMX和AP热分解反应的影响。结果表明,Cr(Ⅲ)配合物的热分解只有一个剧烈的放热过程,残渣量为10.79%。Zn(Ⅱ)配合物的热分解有两个连续的放热过程,残渣量为12.68%。两种配合物对RDX和HM X的催化效果不明显,但使AP高温分解峰的峰温分别提前42.40℃和122.32℃,分解反应的放热量分别增加849.5 J·g-1和971.35 J·g-1,对AP分解反应有好的催化效果。
Two transition metal complexes as 2,6-diamino-3,5-dinitropyridine-1-oxides （ANPyO） with Cr（Ⅲ） and Zn（Ⅱ） were synthesized and characterized by FT-IR spectroscopy and elemental analysis. The effects of Cr（Ⅲ） and Zn（Ⅱ） complexes on the thermal decomposition of RDX , HMX and AP was studied by DSC and TG-DTG. Results show that thermal decomposition of the Cr（Ⅲ） complex only consists of one violent exothermic process with 10.79% residues and the Zn（Ⅱ） complex consists of two consecutive exothermic processes with 12.68% residues. Two complexes have little catalytic effect on the thermal decomposition of RDX and HMX. However, two complexes make the peak temperature of the higher thermal decomposition of AP decrease by 42.40 ℃ and 122.32 ℃, and the exothermic quantity of decomposition reaction increase by 849.5 J·g-1 and 971.35 J·g-1, respectively.
