3,5-二硝基羟基吡啶类含能盐的研究进展

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。

A Review on 3,5Dinitrohydroxylpyridines and Their Salts

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 trinitraminecomposite modified doule based(RDX-CMDB) propellants was reviewed. It was founded that all lead and copper salts derived from these 3,5dinitrohydroxylpyridine compounds present catalytic effects on the combustion of RDX-CMDB propellants,of which the lead and copper salts of 2-hydroxyl-3,5-dinitropyridine(2HDNPPb/2HDNPCu) composite catalyst is the best one. It is predicted that some candidates with better catalytic properties as burningrate 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.
