摘要:
以二氨基乙二肟与乙酰氧基乙酰氯为原料,经环化、水解、硝化合成了新型熔铸炸药液相载体3,3’-联(1,2,4-噁二唑)-5,5’-二甲硝酸酯(BODN),总收率为54%,并采用红外光谱、核磁共振、元素分析等进行了结构表征;优化了水解与硝化反应条件;基于分离、鉴定反应副产物的实验结果,探讨了BODN环化反应机理;利用DSC法研究了BODN与RDX、HMX、CL-20的相容性;采用EXPLO5软件预估了RDX、HMX、CL-20为固相的BODN基熔铸炸药的爆轰参数。结果表明,水解反应较优条件为:以碳酸钾为水解试剂在甲醇中回流,其中,3,3’-联(1,2,4-噁二唑)-5,5’-二甲醇乙酸酯和碳酸钾的摩尔比为10:1,反应2 h;硝化反应较优体系为98%发烟硝酸/醋酐体系,其中,98%发烟硝酸、醋酐体系及3,3’-联(1,2,4-噁二唑)-5,5’-二甲醇的摩尔比为10:5:1,反应10 h;BODN分解峰温203.2℃,与RDX、HMX和CL-20均可良好相容;BODN/CL-20(质量比7:3)理论爆速达8 595 m/s,较TNT/CL-20爆速提高约900 m/s。
Abstract:
Using diaminoglyoxime and 2-chloro-2-oxoethyl acetate as raw materials, a melt-casting explosive, 3,3’-bi(1,2,4-oxadiazole)-5,5’-diylbis(methylene)dinitrate (BODN), was synthesized via coupling-dehydration cyclization, hydrolysis and nitration with an overall yield of 54%, and its structure was characterized by IR, 1H NMR, 13C NMR and elemental analysis. The reaction conditions of hydrolysis and nitrition were optimized. Based on the separation and identification of reaction by-product, the mechanism of BODN coupling-dehydration cyclization reaction was discussed. The compatibilities of BODN with RDX, HMX and CL-20 were investigated by DSC method. The detonation parameters of BODN-based melt-casting explosives with RDX, HMX and CL-20 as solid phase were predicted by EXPLO5 software. The results show that the preferred hydrolysis conditions are as follows:n([3,3’-bi(1,2,4-oxadiazole)]-5,5’-diylbis(methylene)diacetate):n(K2CO3) is 10:1 and the reacting time is 2 h with reflux in CH3OH and K2CO3 as hydrolysis solvent. The preferred reaction conditions for nitrition are:under 98% fuming nitric acid/acetic anhydride system, the molar ratio of the 98% fuming nitric acid/acetic anhydride/[3,3’-bi(1,2,4-oxadiazole)]-5,5’-diylbis(methylene) is 10:5:1,reaction time of 10 h. The decomposition peak temperature of BODN is 203.2℃ and it has good compatibility with RDX, HMX and CL-20. The theoretical detonation velocity of BODN/CL-20 with a mass ratio of 7:3 reaches to 8 595 m/s, 900 m/s higher than that of TNT/CL-20.
