摘要:
以1-氨基-1-肼基-2,2-二硝基乙烯(HDNEA)和乙氧基亚氨基丙酸乙酯盐酸盐(EPC)为原料,经环化、硝化、碱解反应得到了两种高能不敏感离子盐3,5-双(二硝甲基)-1,2,4-三唑单肼盐(HDNMT)和单胺盐(ADNMT),并采用红外光谱、1H NMR、13C NMR及元素分析等对其结构进行了表征;采用DSC和TG-DTG法研究了HDNMT和ADNMT的热行为;采用NASA-CEA软件,在标准条件(pcpo=70:1)下计算了含HDNMT或ADNMT的改性双基推进剂(CMDB)的能量性能。结果表明,合成的两种离子盐与HDNMT和ADNMT预期结构相符,合成收率分别为41.3%和47.6%;分解点温度分别为193.3℃和147.0℃,单肼盐表现出比单胺盐更好的热稳定性;含两种离子盐的CMDB推进剂的理论比冲分别为2 602.8和2 584.4 N·s/kg,特征速度分别为1 603和1 590 m/s,表明两种离子盐在固体推进剂领域有较大的应用前景。
Abstract:
Using 1-hydrazinyl-2,2-dinitroethenamine and ethyl 3-ethoxy-3-iminopropanoate hydrochloride as primary materials, two kinds of insensitive energetic ionic salts, mono-hydrazinium 3,5-bis(dinitromethyl)-1,2,4-triazolate(HDNMT) and mono-ammonium 3,5-bis(dinitromethyl)-1,2,4-triazolate (ADNMT), were synthesized via the reactions of cyclization, nitration and alkali-hydrolysis. Their structures were characterized by FT-IR, 1H NMR, 13C NMR and elemental analysis. The thermal behaviors of HDNMT and ADNMT were studied by DSC and TG-DTG. The energy characteristics of modified double-base (CMDB) propellant containing HDNMT and ADNMT were calculated by NASA-CEA software under the standard condition(pc:po=70:1). The results show that the structures of the two synthesized ionic salts are consistent with the prospective structures and the yield of HDNMT and ADNMT are 41.3% and 47.6%, respectively. The peak temperatures of the exothermic decomposition reaction are 193.3 and 147.0℃, respectively. The theoretical specific impulse (Isp) of CMDB propellant containing the two ionic salts are 2 602.8 and 2 584.4 N·s/kg, and the characteristic velocity (C*) are 1 603 and 1 590 m/s, respectively, showing that the two ionic salts have great application prospects in the field of solid propellant.
