用DSC研究了硝化棉(NC,11.92%N)的一级自催化分解反应动力学。结果表明:50%转化率前的DSC曲线可用一级自催化方程描述:dyRTy(1-y)dt=-1016.4exp-210380RTy-1016.7exp-17150050%转化率后的DSC曲线可用如下反应动力学方程描述:dyRTy2.71 (n≠1)RTy (n=1)和 dydt=-1016.3exp-174280dt=-1016.8exp-171300
The first-order autocatalytic decomposition kinetics of nitrocellulose (NC, 11.92% N) was studied by DSC. The results show that the DSC curve before 50% conversion can be described by a one-step autocatalytic equation: dyRTy (1-y) dt = -1016.4exp- 210380RTy- 1016.7exp- 17150050% The DSC curve after the conversion can be obtained by the following reaction kinetics equation Description: dyRTy2.71 (n ≠ 1) RTy (n = 1) and dydt = -1016.3exp -174280dt = -1016.8exp -171300
