1,1′-二甲基-5,5′-偶氮四唑一水合物是一种有一定实用价值的含能材料。该化合物在性升温条件下线的热行为和动力学未见文献报道。我们用Calvet微热量热计、DSC、TG-DTG和质谱仪考察了该化合物的热分解和电子轰击下的裂解过程。这对于揭示该化合物在高温下的变化规律和快速评定其耐热性是有益的。实验试样 1,1′-二甲基-5,5′-偶氮四唑(1)和2,2′-二甲基-5,5′-偶氮四唑(2)按文献[1]的方法制备和纯化。用玛瑙研钵轻轻压成粉末,于45℃和10~(-2)mmHg条件下干燥8h,置硅胶
1,1’-dimethyl-5,5’-azotetrazole monohydrate is a kind of useful material with a certain practical value. The thermal behavior and kinetics of the compound under the condition of mild temperature increase have not been reported in the literature. We used Calvet microcalorimeter, DSC, TG-DTG and mass spectrometer to investigate the pyrolysis of the compound and the pyrolysis under electron impact. This is useful for revealing the variation of the compound at high temperatures and quickly assessing its heat resistance. Experimental samples 1,1’-dimethyl-5,5’-azotetrazole (1) and 2,2’-dimethyl-5,5’-azotetrazole (2) ] Method of preparation and purification. Gently pressed into an agate mortar powder, dried at 45 ℃ and 10 ~ (-2) mmHg conditions 8h, set silica gel
