摘要：
Deuterated nitroguanidine (NQ-d4) and deuterated 1,1-diamino-2,2-dinitroethylene (FOX-7-d4) were synthesized via H/D exchange starting from nitroguanidine (NQ) and 1,1-diamino-2,2-dinitroethylene (FOX-7). The target products were characterized by IR, NMR (1H and 13C), HPLC, TG-DTG, DSC and neutron diffraction. DSC/TG data show that the decomposition temperatures of NQ-d4 and FOX-7-d4 were 2.5 ℃ and 2.6 ℃ higher than those of NQ and FOX-7, respectively. The deuteration rates of NQ-d4 and FOX-7-d4 are respectively 95.27% and 98.87% as measured by neutron diffraction. The purities of NQ-d4 and FOX-7-d4 are respectively 99.51% and 99.28% obtained by HPLC via area normalization method. © 2020, Editorial Board of Chinese Journal of Energetic Materials.
