摘要
综述了国内外关于三种3,5-二硝基羟基吡啶类化合物(2-羟基-3,5-二硝基吡啶(2HDNP)、4-羟基-3,5-二硝基吡啶(4HDNP)和4-羟基-3,5-二硝基吡啶氮氧化物(4HDNPO))金属盐和非金属盐的合成、晶体结构、热化学性质和非等温热分解动力学行为,以及它们对固体推进剂燃烧性能影响的研究进展。三种3,5-二硝基羟基吡啶类化合物铅铜盐都表现出对RDX-CMDB微烟推进剂明显的催化燃烧作用和降低压力指数的能力,其中以2HDNPPb/2HDNPCu复合催化体系催化效果最好。预计随着更多此类化合物及其含能盐的合成及应用研究,会发现一些综合性能优良的固体推进剂燃速调节剂。
The current development of three 3,5-dinitrohydroxylpyridines （2-hydroxyl-3, 5-dinitropyridine, 4-hydroxyl-3, 5- dinitropyridine and 4-hydroxyl-3,5-dinitropyridine-N-oxide） derived metal and nonmetal salts concerning their syntheses, crystal structures, thermochemical properties and thermokinetic behaviors as well as their effects on combustion properties of cyclotrimethylene trinitramine-composite modified doule based（RDX-CMDB） propellants was reviewed. It was founded that all lead and copper salts derived from these 3,5-dinitrohydroxylpyridine compounds present catalytic effects on the combustion of RDX-CMD B propellants, of which the lead and copper salts of 2-hydroxyl-3,5-dinitropyridine （ 2 H D N PPb/2 H D N PCu ） composite catalyst is the best one. It is predicted that some candidates with better catalytic properties as burning-rate modifiers for combustion of solid propellants will be found,when more and more novel 3,5-dinitrohydroxylpyridine derivatives and their energetic salts are synthesized and their catalytic efficiencies are evaluated.
