Explanation

The scientific name is 2,4,6-trinitro-N-nitro-N-methylaniline or 2,4,6-=nitrobenzenenitramine. The pure product is a colorless crystal that quickly turns yellow under light. Industrial products all appear light yellow. Moisture absorption 0.04% (30t:. relative humidity 90%), non volatile at room temperature. Almost insoluble in water, insoluble in carbon tetrachloride and carbon disulfide, slightly soluble in ether, ethanol, and chloroform, soluble in benzene, toluene, xylene, and dichloroethane, easily soluble in acetone and ethyl acetate. density 1.71g/cm3, melting point 129.5 ° C (accompanied by decomposition). The explosion heat at the density of 1.69g/cm3 is 4.87MJ/kg (liquid water); When the density is 1.71g/cm3, the detonation velocity is 7.85km/s, and the detonation pressure is 21.3GPa; The explosion temperature at the density of 1.631g/cm3 is about 3100K; The full explosion capacity at the density of 1.55g/cm3 is 740L/kg. The impact sensitivity is 48% (10kg, 25cm), the friction sensitivity is 12% (swing angle 90 °), the work capacity is 410mL (lead wall reaming value) or 130% (TNT equivalent), and the ferocity is 19? 20mm (compression value of lead column) or 120% (weight loss of the first 4.8h at TNT equivalent 100aC is 0.1%. Let; V, N-dimethylaniline first salt with sulfuric acid and then nitrate. It can be used for booster explosive columns, detonating cords and detonators. Due to its high toxicity and can be replaced by other explosive, it is gradually eliminated. Now it is mainly used as the standard propellant for mechanical sensitivity test.
