摘要 在298.15K下用精密转动弹热量计测得4-羟基-3,5-二硝基吡啶铅盐(4HDNPPb)的燃烧能△cU为(-7385.82±3.14)J·g^-1;据此计算的标准摩尔燃烧焓△cHm^θ破为(-4499.63±1.92)kJ·mol^-1,标准摩尔生成焓△fHm^θ为(-796.65±2.32)kJ·mol^-1。研究了4HDNPPb和含能铜盐(或惰性铜盐)的混合物在RDX,CMDB推进剂燃烧中的催化作用,结果表明,复合催化剂体系:2.5%4-羟基-3,5-二硝基吡啶铅盐(4HDNPPb)与0.5%2-羟基-3,5-二硝基吡啶铜盐(2HDNPCu)的混合物,或2.5%4HDNPPb与0.5%邻苯二甲酸铜(Ф-Cu)的混合物,使RDX—CMDB推进剂的燃烧在所测压力范围内(2~20MPa)有较高的催化效率,压力指数小于0.3。 The constant-volume combustion energy A,U (4HDNPPb, s. 298. 15 K) of lead skit of 4-hydroxy-3,5-dinitropyridine (4HDNPPb) was determined as ( -7385.82 Ф3.14) J · g^-1 at 298.15 K by a precise rotating bomb calorimeter. The standard molar enthalpy of combustion △cHm^θ (4HDNPPb, s, 298.15 K) and standard molar enthalpy of formation △cHm^θ (4HDNPPb, s, 295.15 K ) of 4HDNPPb were calculated to be ( -4499.63 ± 1.92) kJ · mol^-1 and ( -796.65 ±2.32) kJ · mool^-1 ,respectively. Moreover,the catalysis of composite catalyst system,4HDNPPb/encrgetie copper salt mixture or 4HDNPPb/non-energetie copper salt mixture on the combustion of RDX-CMDB propellant was investigated. The results show that composite catalyst, 2.5 %/0.5 % -ω (4HDNPPb) / ω ( 2 HDNPCu ) mixture or 2.5 %/0.5 % -ω ( 4 HDNPPb )/ω ( Ф-Cu, copper phthalate ) mixture, has higher catalytic efficiency in catalyzing RDX-CMDB propellant combustion and enables the pressure exponent of the propellant to be less than 0. 30
