摘要
通过改变加料方式来研究脲或硝基脲在硝化剂中与乌洛托品硝解碎片进行缩合反应的形式。采用不同的脲或硝基脲的加料方式时产物 RDX酮的得率是不同的。在给定的几种硝化剂中的研究结果表明 :先加脲或硝基脲后加乌洛托品的加料方式得到最高得率RDX酮 ,而后加脲或硝基脲的加料方式获得 RDX酮的得率最低。相同条件下用等摩尔数的硝基脲代替脲时 ,RDX酮得率较高。由此表明了在生成 RDX酮的反应过程中 。
This paper presents the studies on the reaction form of urea or nitrourea which condenses with nitrolysis fragments of urotropine to form Keto RDX in nitrating agents. Different yields of Keto RDX resulted from different methods to feed urotropine and urea (or nitrourea). Studies in several kinds of nitrating agents manifested that feeding urea or nitrourea before urotropine resulted in the highest yield of Keto RDX while feeding urea or nitrourea after urotropine tended to the lowest yield, and that feeding nitrourea usually yielded higher than feeding same mole amount of urea did under same experimental conditions. This proved that nitrourea was a more suitable reactant than urea to synthesize Keto RDX.
