摘要
以乙酰乙酸乙酯为起始原料,用高压法合成了前体化合物4-甲基-3-氨基呋咱(AMF),在盐酸催化下使AMF与甲醛反应得到亚甲基-双-(3-氨基-4-甲基呋咱)(MBAMF),对MBAMF硝化得到目标化合物亚甲基-双-(3-硝氨基-4-甲基呋咱)(MBNMF)。用DSC-TG研究了MBNMF的热分解特性,测定了MBNMF的感度和燃烧热。结果表明,与HMX相比,MBNMF的机械感度和静电感度低,热分解峰温为149.7℃,密度1.63 g/cm3,燃烧热18 628.8 kJ/kg,生成焓达1 694.4 kJ/mol,表明MBNMF是一种新型高能物质。
With ethyl acetoacetate as starting material, 3-amino 4 methylfurazan (AMF) was prepared through a high pressure process, and methylene-bis-(3-amino-4-methylfurazan)(MBAMF) was synthesized by reaction of AMF and formaldehyde with hydrochloric acid as catalyst. Methylene-bis-(3-nitramino-4-methylfurazan) (MB- NMF) was obtained by nitration of MBAMF. Thermal decomposition characteristics of MBNMF was studied by DSC-TG, and sensitivity and heat of combustion of MBNMF was determined. The results show that the mechanical sensitivity and static electricity sensitivity of MBNMF was lower than those of HMX, and MBNMF decomposed at 149. 7℃. Its density was 1. 63 g/cm3 , and standard heat of combustion 18 628.8 kJ/kg. Its enthalpy of formation was 1 694. 4 kJ/mol, higher than that of HMX ( 104. 8 kJ/mol) , revealing that MBNMF is a novel energetic material.
