Explanation

1,3,5-trinitro-1,3,5-triaazacyclohexane, usually represented by the code RDX. RDX is a white rhombic crystal, non hygroscopic, and non volatile compound at room temperature. It is insoluble in water and chloroform, slightly soluble in ethanol, ether, benzene, toluene, chloroform, carbon disulfide, and ethyl acetate, but easily soluble in acetone, dimethylformamide, cyclohexanone, cyclopentanone, and concentrated nitric acid. Specific properties include: melting point is about 204 ° C (accompanied by decomposition), industrial products are usually 200 ° C, and density is about 1.8168 g/cm 3， The explosion tcmperature is about 230 ° C (5 seconds), and the explosion heat is 6.32 MJ/kg (in liquid water, the density is 1.70 g/cm 3）， The detonation velocity is 8.64 km/s (density 1.767 g/cm 3）， The explosion pressure is 33.8 GPa (density 1.767 g/cm 3）， explosion temperature is about 3700K (density 1.80 g/cm 3）， The total explosive capacity is 890 L/kg, and the friction sensitivity is 80% (10 kg, 25 cm). It is usually used to manufacture detonators, booster charge and detonating cord, especially passivation hexogen. In addition, RDX is used to load artillery shells, missile warheads, torpedoes, mines and other weapons, and is also a high-energy component of propellant. The preparation of RDX usually involves direct nitration or acetic anhydride method. Because of its reliable performance and stable manufacturing process, RDX has become an important high power explosive, which is widely used in military and civil fields.
