Explanation

The product obtained from recrystallization from dichloroethylene is a green or light yellow hexahedral crystal, soluble in benzene and dichloroethane. It is insoluble in chloroform and carbon tetrachloride and quickly hydrolyzes in humid air. density 2.01g/cm3, melting point 254-258 ℃. The explosion point is 282 ℃ (5s), the detonation velocity is 9.33km/s (when the density is 1.95.6g/cm3), the impact sensitivity is 56% (10kg. 25cm), and the weight loss is 1.8% at 120 ℃ for 12h. The detonation velocity is the highest among known aromatic nitrocompound explosive, but its stability is poor. It becomes yellow powder after absorbing water, and has no use value at present. The trinitrobenzene is partially reduced to dinitroaniline, the latter is first treated with nitric sulfur mixed acid to obtain pentanitroaniline, and then oxidized with persulfuric acid to obtain hexanitrobenzene.
