s–1 and 33.64 GPa, respectively, which are far superior to the detonation performance of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), while its sensitivity is identical with that of TATB. In addition, four derivatives (1a, chloride; 1b, nitrate; 1c, perchlorate; and 1d, dinitramide) were prepared on the basis of the weak base site (N–O group) and show excellent energetic properties. By combining a series
实现开发不敏感的高能分子 ( IHEM ) 的目标是一项重大挑战。在这项研究中,3,5-diamino-6-hydroxy-2-oxide-4-nitropyrimidone ( IHEM-1 ) 是由 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide hydrate 一步合成的(ICM-102 水合物)。化合物IHEM-1的密度为 1.95 g cm –3,分解温度为 271 °C。其爆速和爆压分别为 8660 ms –1和 33.64 GPa,远优于 1,3,5-三氨基-2,4,6-三硝基苯(TATB)的爆轰性能,而其灵敏度与TATB 的那个。此外,还有四种衍生物(1a,氯化物;1b,硝酸盐;1c,高氯酸盐;和1d,二硝酰胺)是在弱碱位点(N-O 基团)的基础上制备的,并显示出优异的能量特性。IHEM-1综合了制备简单、收率高、密度大、在水溶液中
