This proved that nitrourea was a more suitable reactant than urea to synthesize Keto-RDX.

由此表明了在生成RDX酮应过程中，硝基脲上比脲更应形式。

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.

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应形式。
