99 4,6-Dinitrobenzofuroxan
colorless crystals
empirical formula: C4H2N8O10
molecular weight: 322.1
oxygen balance: +5.0%
nitrogen content: 34.79%
density: 2.01 g/cm3 detonation velocity, confined:
9150 m/s = 30000 ft/s at r = 1.95 g/cm3 deflagration point: 237 °C = 459°F
impact sensitivity: 0.15–0.2 kp m = 1.5–2 N m
The product is interesting because of its high density and also high
detonation velocity.
Sorguyl is not hygroscopic, but it decomposes easily by hydrolysis. It is
insoluble in hydrocarbons and chlorinated hydrocarbons, but soluble in
numerous solvents.
It decomposes when mixed with molten W TNT.

4,6-Dinitrobenzofuroxan
4,6-Dinitrobenzfuroxan; 4,6-dinitrobenzofurazan-1 -oxide; dinitro-dinitrosobenzene
yellow-gold needles
empirical formula: C6H2N4O6
molecular weight: 226.1
oxygen balance: – 49,5%
nitrogen content: 24.78%
melting point: 172 °C
Dinitrobenzofuroxan is practically insoluble in water, alcohol and benzine.
It is readily soluble in aromatic hydrocarbons and boiling acetic
acid.
The compound is obtained by means of direct nitrating of benzofurazan-1-oxide
with concentrated nitric and sulfuric acid, or by heating
W Trinitrochlorbenzene (Picrylchloride) with sodium azide in acetic
acid in a water bath.
