- W2383314003 abstract "Bis[2-(5-nitrotetrazol-2-yl)-2,2-dinitroethyl]nitroamine(NTEA)was synthesized using 2-dinitromethyl-5-nitro-tetrazole potassium salt(KDNMNT)as raw material via condensation reaction of KDNMNT with methenamine in H2SO4-H2 O medium and nitration reaction of bis[2-(5-nitrotetrazol-2-yl)-2,2-dinitroethyl]amine(BNTDNEA)in H2NO3 medium with the total yield of 30.20%.The structures of BNTDNEA and NTEA were characterized by IR,NMR and elemental analysis.The density(ρ),enthalpy of formation[ΔfHm],detonation velocity(D)and detonation pressure(p)of NTEA were theoretically calculated by quantum chemical method.Results show that the optimized synthesis conditions of BNTDNEA are n(KDNMNT)∶n(HMTA)=2.5∶1.0and reaction temperature 40℃.The optimized synthesis conditions of NTEA are 98% HNO3 as nitration system and nitration reaction temperature 5℃.The values ofρ,ΔfHm,Dand pof NTEA are 1.97g/cm3,416.02kJ/mol,9.336km/s and 41.53 GPa,respectively,revealing that the energy level of NTEA approaches to that of CL-20." @default.
