摘要
利用DSC,TG DTG及FT IR技术对4,6 二硝基 7 羟基 7 氢化苯并氧化呋咱钾(KDNBF)的热分解过程进行了研究。结果表明,230℃时,固体残渣中含有RCOOK,KNCO,RNO2,KNO3,而在306℃时则含有KNC,RCOOK及KNO3。利用Kissinger法与Ozawa Doyle法对KDNBF的热分解过程进行了动力学计算。两种方法所得结果互相吻合,结合本文及文献结果,Arrhenius方程可表达为:lnk=45.2-192600/RT。
The thermal decomposition process of potassium 4,6-dinitro-7-hydroxy-7-hydrobenzofuroxanate (KDNBF) is studied by using DSC, TG-DTG and FT-IR techniques. The results show that the solid residue at 230 ℃ are RCOOK, KNCO, RNO_2 and KNO_3, and at 306 ℃ are KNC, RCOOK and KNO_3, respectively. The Arrhenius parameters of the decomposition reaction are calculated using Kissinger′s and Ozawa-Doyle′s method, indicating that the results obtained by the two methods agree well with each other and the Arrhenius equation of this reaction can be expressed by lnk = 45.2-192600/RT.
