摘　　要：为解决RDX生产过程中废硝酸的再利用问题,采用（a）在分离出RDX后,直接加入一定量尿素水溶液,废硝酸与尿素反应制成硝酸脲,（b）RDX和硝酸脲在稀硝酸中共结晶,生成共晶混合炸药（RDX的质量分数60%-70%）。经测试,其爆炸性能优于两者直接混合炸药,爆速可达7500m/s左右,提高了4%;红外光谱分析结果表明,这种混合炸药是一种具有分子间氢键的共晶体。To solve the waste nitric acid recycle problem from RDX plants, a new technique is used：（a） urea is added to the waste nitric acid after RDX is isolated,thus forming urea nitrate, （b） RDX and urea nitrate inintric acid are cocrystallized to obtain a mixture explosive containing 60%0-70%0 RDX. The test results show that its detonation velocity is 7500m·s^-1,which is 4% more than that of direct mixture of RDX and urea nitrate. Analysed results by IR show that this mixture explosive is an eutectic with intermolecular hydrogen bond.
