新型钝感含能增塑剂3-硝基呋咱-4-甲醚的合成与性能研究
Synthesis and Characterization of Novel Insensitive Energetic Plasticizer 3-Nitrofurazan-4-monomethyl Ether
摘要
Abstract
With ethyl cyanoacetate as starting materials,3-aminofurazan-4-carboxylic acid(AFCA) was prepared through one-pot reaction in 46% yield. And 3-aminofurazan-4-monomethyl alcohol(AFMA) was synthesized by reduction reaction of AFCA through NaBH4/ZnCI2 system. 3-Nitrofurazan-4-monomethyl alcohol ( NFMA) was obtained by oxidation of AFMA through H2O2/H2SO4 system. 3-Nitrofurazan-4-chloromethylene( NFCM) was obtained by chlorination of NFMA and SOCI2. And 3-nitrofurazan-4-mono-methyl ether( NFME) was synthesized by etherification reaction of NFCM and sodium methoxide in 45% yield. Their structures were characterized by FT-IR, MS, NMR and DSC-TG, and sensitivity and heat of combustion of NFME were measured. The results show NFME has a low melting point of -67℃ and is insensitive to impact and friction. NFME decompose at 169.9℃, and its standard combustion heat is 18628.8 kJ ? Kg-1 , formation enthalpy 1694.4 kJ ? Mol-1, higher than nitrate plasticizer Bu-NENA, TMETN, BTTN and NG.关键词
