Nitration of TAIW to Synthesize CL-20 Using N2O5/HNO3 as Nitrating Agent
CL-20 is usually prepared via nitration with the concentrated mineral acid as catalyst, but this technique is one of the most environmentally harmful processes. In this article, CL-20 was synthesized in a nitration of tetraacetylhexaazaisowurtzitane (TAIW) by using N2O5/HNO3 as the nitrating agent. The product yield can reach 86.1% and the purity is 99%. The structure of the compound was characterized by NMR, IR and MS. Meanwhile, the effects of reaction temperature, reaction time, and the molar ratio of reagents on the yield were also investigated. The experimental results showed the optimal reaction conditions are reaction temperature 40℃, reaction time 1h, and the molar ratio of TAIW: N2O5: HNO3 being 1:4:36. Meanwhile, the crystal formation and nitration mechanism were also discussed.
