惰性溶剂中黑索今的热分解机理

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

Thermal Decomposition Mechanism of RDX in Inertial Solvents

Solvents can be divided into inertial and active groups according to their effec ts on RDX decomposition rate. Active solvents accelerate RDX decomposition rate, inertial solvents do not affect RDX decomposition rate or inhibit RDX decomposi tion because of their large viscosity. In this paper thermal decomposition mecha nism of RDX in inertial solvents was studied by means of special Brudon apparatu s. On basis of N-NO 2 bond dissociation many secondary reactions were outlined , and with these reactions our own and related literature experimental facts can be explained: in ertial solvent effect on RDX decomposition rate, effect of RDX concentration in benzene on RDX thermal gas producing and the formation of nitr oso-RDX. The outlined mechanism makes the knowledge of thermal decomposition of nitramine in solutions one step forward.
