Abstract:

The intermediate products of N,N'-(1,3,4,5,7,8-hexanitrooctahydro-diimidazo[4,5-b∶4',5'-e]pyrazine-2,6(1H,3H)-diylidene)dinitramide(ONIP) were studied via quantum chemistry method. When the ONIP is not nitrified completely, several intermediate products under different degree of nitrification are obtained. And what’s more, each intermediate has several isomers. We used the Gaussian 03 software to research these isomers. The thermodynamic selective products could be identified. Then the structures, density and some other important properties were calculated under B3PW91 level and 6-31G++(d,p)basis set with density functional theory. The results showed that the intermediate with six nitro groups owns very good detonation performance. It may be easier to be synthetized than ONIP, and more inactive than ONIP.

Key words: N, N'-(1, 3, 4, 5, 7, 8-hexanitrooctahydro-diimidazo[4, 5-b∶4', 5'-e]pyrazine-2, 6(1H, 3H)-diylidene)dinitramide, Intermediate with nitro group, Density functional theory, Detonation property
