根据溶剂对 RDX热分解行为的不同影响可将溶剂分为活性和惰性两类。活性溶剂加速 RDX热分解 ,惰性溶剂对 RDX热分解速率无影响或因其粘度较大而降低了热分解速率。本文用布氏压力法研究了 RDX在惰性溶剂中热分解机理 ,补充了许多二级反应 ,借助这些二级反应用初始步断裂 N- NO2 键机理较好地解释了溶剂粘度对 RDX热分解速率的影响和 RDX在苯中浓度对放气量及反应中间产物亚硝基黑索今得率的影响。所提出的机理丰富、完善、发展了二元硝胺炸药热分解理论
Depending on the solvent’s effect on the thermal decomposition behavior of RDX, the solvent can be divided into two types, active and inert. The active solvent accelerates the RDX thermal decomposition, the inert solvent has no effect on the RDX thermal decomposition rate or decreases the thermal decomposition rate due to its higher viscosity. In this paper, the thermal decomposition mechanism of RDX in inert solvents was studied by using Brinell pressure method, which supplemented many second-order reactions. With the help of these second-order reactions, the initial step-breaking mechanism of N-NO2 was used to better explain the influence of solvent viscosity on the thermal decomposition rate of RDX And the effect of RDX concentration in benzene on the deflation rate and the yield of nitroso-safranin, a reaction intermediate. The proposed mechanism is rich, perfect, developed the thermal decomposition theory of binary nitramine explosives
