... derivative of benzene. It is a yellow crystalline powder that melts at 266 °F (130°C) and explodes when heated to 367 °F (1 86 C). It is more sensitive to shock than TNA and has a higher rate of detonation ... in bulk. The melting point varies from 2 165 to 2714°F (1185 to 1490°C), but the preferred range is 2282 to 2 462 °F (1250 to 1350°C). Mohs hardness is 6 to 6. 5, and the index of re...
