Catalytic reaction of ammonium perchlorate with energetic cobalt complex of 2,6-diamino-3,5-dinitropyrazine-1-oxide during thermal decomposition process

Abstract The purpose of this work was to study the catalytic reaction and its mechanism of ammonium perchlorate (AP) with cobalt complex of 2,6-diamino-3,5-dinitropyrazine-1-oxide (Co-LLM-105) during thermal decomposition process. At first, the catalytic performance of Co-LLM-105 on the thermal decomposition of AP was investigated by TG–DSC, TG-FTIR, non-isothermal kinetic and α – T kinetic curves analyses. Secondly, the thermal decomposition mechanism of Co-LLM-105 in the absence and presence of AP was proposed based on TG, DTG, DSC and thermolysis/RSFTIR analyses. The results showed that Co-LLM-105 exhibited excellent catalytic activity on the thermal decomposition of AP. Meanwhile, AP also exhibited some catalytic effects on the thermal decomposition of Co-LLM-105. Both of the components had catalytic effects on each other during the process. The formation of active CoCO 3 , Co 3 O 4 , CoO and Co(NH 3 ) 6 (ClO 4 ) 2 in situ in the system accounted for the higher catalytic activity of Co-LLM-105 for the thermal decomposition of AP was deduced. Graphical Abstract Co-LLM-105 exhibited excellent catalytic activity on the thermal decomposition of AP. Meanwhile, AP also exhibited some catalytic effects on the thermal decomposition of Co-LLM-105. Both of the components had catalytic effects on each other during the process.
