Abstract:
In order to find the efficient and insensitive energetic catalyst,three transition metal complexes as 2,6-diamino-3,5-dinitropyridine-1-oxides(ANPyO)with Ni(Ⅱ),Cu(Ⅱ)and Fe(Ⅱ)are synthesized and characterized by FT-IR spectroscopy,elemental analysis and TG-DTG technologies.The compatibility with 1,3,5-trinitrohexahydro-1,3,5-triazine(RDX),octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine(HMX),nitrocellulose(NC)and aluminum(Al)powder is also investigated separately using DSC technology,showing that Ni(Ⅱ)and Cu(Ⅱ)complexes have better compatibility.The kinetic parameters of the first exothermic process of three complexes are studied by the Kissinger's and Ozawa-Doyle's methods.The sensitivity test results show that the complexes are insensitive energetic compounds which have lower sensitivity compared with ANPyO.Meanwhile,these three complexes are used as catalysts and their activity towards the thermal decomposition of ammonium perchlorate(AP)are evaluated.The results show all the complexes can accelerate the processes and Cu(Ⅱ)complex has the best catalytic effect.
