N2 O5／HNO3硝解 TAIW 合成 CL-20
Synthesis of CL-20 by Nitrolysis of TAIW with N2 O5/HNO3
摘要
Abstract
2,4,6,8,10,12-Hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20)was prepared via nitrolysis of 2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo [5,5,0,03 ,11 05 ,9 ]dodecane (TAIW)as starting material and N2 O5/HNO3 as nitrating agent.Through studying the effect of the reaction conditions such as filling type for nitrolysis of TAIW with N2 O5/ HNO3 ,temperature,the amount of HNO3 and N2 O5 ,reaction time,the amount of the diluted water on the yield and purity of CL-20,the optimal reaction conditions are determined as:reaction temperature 60-80 ℃,reaction time 7 h,the ratio of m(TAIW)∶m(N2 O5 )∶V (HNO3 )of 3 g∶4 g∶15 mL,and addition of diluted water in the post process 20 mL,at this time,the yield of CL-20 is 82.34% ,and its purity is 98.29%.When 10%CF3 SO3 H/resin is used as catalyst,the yield is up to 87.35% ,its purity remains basically unchanged and the recovery rate of catalyst reaches to 99.15%.This method can avoid the use of sulfuric acid and reduce the pollution of the waste acid with strong industrial application prospect.关键词
