1,3,5-Triacetyl hexahydro-1,3,5-triazaine (TRAT) was prepared from acetonitrile and 1,3,5-trioxane in the presence of sulfuric acid as catalyst according to a literature process, and TRAT was then nitrated with N2O5/HNO3 as nitrating agent to RDX Experiment results showed that when the reaction temperature was 50℃ , reaction time lh and molar ratio of n(N2O3) : n(HNO3) : n(TRAT) =6 : 60 : 1, the yield of the RDX was up to 87.4%. The structure of the compound was characterized by NMR and IR. The main side product was researched and confirmed by MS.%采用乙腈和三聚甲醛为原料、浓硫酸为催化剂合成三(N-乙酰基)六氢化均三嗪(TRAT),再以N2O5/HNO3为硝解剂合成黑索今(RDX).实验表明:当摩尔比n(N2O5)∶n(HNO3)∶n(TRAT) =60∶6∶1,硝解温度50℃,反应时间为1h时,RDX的最高产率可达87.4％.产品通过红外光谱、核磁共振进行了表征,并对副产物进行了研究,副产物通过质谱验证.
