Explanation

The scientific name is 2,4,6-trinitrotoluene, and the common code is TNT. It is the most important military and civilian single explosive with the largest amount of use. The pure product is a colorless needle like crystal, while the industrial product is a light yellow flake like substance with low moisture absorption. It is not volatile at room temperature and is difficult to dissolve in water. It is slightly soluble in ethanol, carbon tetrachloride, and carbon disulfide, and is easily soluble in pyridine, acetone, toluene, benzene, and chloroform. The density of crystal is L654g/cm3, the condensation point is 80.9 ° C (80.2X for military products: or 80.1T, and the explosion point is 475X: (5s) or 295C (5min). The detonation velocity at density L60g/cm3 is 4.54MJ/kg (liquid water); the detonation velocity at density 1.64g/cm3 is 6.92km/s, and the detonation pressure is 16.9GPa (density 1.60g/cm3, grain diameter 20mm); the detonation temperature at density 1.61g/cm3 is about 2600K; The full explosion capacity is 750L/kg when the density is 1.50g/cm3, and the work capacity is 285mL (lead wall reaming value). The brisance is 16_ (Lead column compression value), impact sensitivity 4% -8% (10kg, 25cm)? Friction sensitivity (swing angle 90 °) 4% -6%, 150X: no decomposition at lower temperature, 0.8% decomposition at 200t requires 385miiu, which is obtained by multi-stage continuous nitration of toluene through nitrate sulfur mixed acid, gradually introducing three nitros into toluene molecule, and refining with sodium sulfite. The manufacturing process is mature, the source of raw materials is sufficient, the explosion performance and chemical stability are good, the mechanical sensitivity is low, and the charging process is satisfactory. It can be pressed, cast, or used alone, In particular, it can form a large number of composite explosive with a variety of heavy explosives and other substances. Widely used for loading various shells, aviation bombs, rockets, missiles, landmines, mines, torpedoes, grenades, and explosive equipment.
