Abstract
以3,4-双（3＇-氨基呋咱-4＇-基）呋咱（BATF）为原料,经Caro’s acid氧化制备了3,4-双（3＇-硝基呋咱-4＇-基）呋咱（BNTF）,收率为93%;基于BNTF分子中的NO2反应性,与水合肼、氨水等发生亲核取代、环化反应,合成了含能化合物7H-三呋咱并[3,4-b：3＇,4＇-f：3＂,4＂-d]氮杂环庚三烯（HTFAZ）和7-氨基-三呋咱并[3,4-b：3＇,4＇-f：3＂,4＂-d]氮杂环庚三烯（ATFAZ）.在硝酸-醋酐体系中氧化HTFAZ得到新化合物7,7＇-二（呋咱[3,4-b：3,4＇-d：3＂,4＂-f]氮杂环庚三烯）（BTFZ）,采用红外光谱、核磁共振、元素分析和质谱等进行了结构表征.培养了HTFAZ单晶,X射线单晶衍射分析表明：HTFAZ晶体结构属单斜晶系,空间群为P2（1）/n,a=0.7252（15）nm,b=0.6458（14）nm,c=1.6814（4）nm,V=0.7781（3）nm3,Z=4,Dc=1.871 g·cm^-3,F（000）=440,R1=0.0353,w R2=0.0895.开展了HTFAZ,ATFAZ和BTFZ的物化、爆轰性能和热性能研究,其中HTFAZ密度1.871 g·cm^―3、生成焓733.7kJ·mol^-1、熔点193.1℃、分解点345.1℃、爆速8416.5 m·s^-1、爆压为32.9GPa;ATFAZ密度1.788 g·cm^-3、生成焓831.2kJ·mol^-1、熔点204～207℃、分解点323.7℃、爆速8300 m·s^-1、爆压为30 GPa;BTFZ密度1.862 g·cm^-3、生成焓1752.4kJ·mol^-1、分解点280.2℃、爆速7924.5 m·s^-1、爆压为28.42 GPa.
