Synthesis, Characterization and Performance Prediction of Two Kinds of Novel Energetic Ionic Salts of 2-Dinitromethyl-5-nitrotetrazolate
摘要
Abstract
Two kinds of novel energetic ionic salts of 2-dinitromethyl-5-nitrotetrazolate 3-amino-1,2,4-triazole salt (3-ATDNMNT) and 2-dinitromethyl-5-nitrotetrazolate 4-amino-1,2,4-triazole salt (4-ATDNMNT),were synthesized via neutralization reaction using amino-1,2,4 triazole and 2-dinitromethyl-5-nitrotetrazolate(HDNMNT) as raw materials.Their yields were 95.4% and 96.7%,respectively.Their structures were characterized by means of FT-IR,1 H NMR,13C NMR,15 N NMR and elemental analysis.The detonation performances of 3-ATDNMNT and 4-ATDNMNT were calculated by quantum chemical method.Under the standard condition(expansion ratio as 70 ∶ 1),the energy performances of hydroxyl terminated polybutadicne (HTPB) composite propellant containing two kinds of energetic ion salts were calculated by the principle of minimum free energy.The results show that the detonation velocity and the detonation pressure are 8.587 km/s and 33.58 GPa for 3-ATDNMNT and 8.693 km/s and 34.31 GPa for 4-ATDNMNT,respectively.After partly replacing AP with 3-ATDNMNT in HTPB propellant,the theoretical specific impulse of HTPB propellant is up to 2 635.7 N · s/kg.After partly replacing AP with 4-ATD-NMNT in HTPB propellant,the highest theoretical impulse of HTPB propellant is 2 677.2 N · s/kg,when the mass fractions of HTPB,Al,AP and 4-ATDNMNT are 10%,5%,15% and 70%,respectively.关键词
