镧系金属磺酸盐催化剂在CL-20合成中的应用
Application of Lanthanide Sulfonate Catalysts in Synthesis of CL-20
摘要
Abstract
Aiming at the drawbacks of long reaction time and low yield during N2O5/HNO3 nitrifying tetraacetyl-hexaazaisowurtziane (TAIW) to hexanitro-hexaazaisowurtzitane (CL-20),CL-20 was synthesized via nitration of TAIW with N2O5/HNO3,taking five kinds of lanthanide sulfonates including methanesulfonates,benzenesulfonates,p-toluenesulfonates,2-naphthalenesulfonates and trifluoromethanesulfonates as catalysts.The effects of lanthanide sulfonate species,dosage,reaction time and recycle times on the yield and purity of CL-20 were studied.Results show that samarium sulfonates are found to be the most effective catalyst among the catalysts investigated and the Sm(Tos)3 shows the best catalytic activity.When the reaction temperature is 65-75℃,the reaction time is 4h,and the ratio of materials is m(Sm(Tos)3) ∶ m(TAIW) ∶ m(N2O5) ∶ V(HNO3)=0.3g∶ 3g∶ 4g∶ 15mL,the yield and purity of CL-20 are 95.2％ and 98.6％,respectively.After reused five rimes,the catalytic perfomance of this catalyst is not obviously reduced.关键词
