Explosion lower

The temperature of the flame is also of great Importance and most countries have established a certain max temperature. Mallard and LeChatelier chought that the max should be 2200°, but the French Investigating Committee (Commission des Substances Explosives) lowered this limit to 1500° for "couche expls (permissible in coal seams) and 1900° for "roche expls (used for blasting accompanying rock).

Fast Operation with Unstable Intermediates. Diazotization of aromatic amines poses hazards including light, heat, and shock sensitivity, which can all lead to xmcontrolled decomposition of the diazonium salt, creating an explosion. Lower alkyl nitrites have been known to blow up the container even when refrigerated. The explosion hazard is related to the pressure increase caused by nitrogen generation and to the highly exothermic nature of the reaction. De Mello et al. minimized the transportation time between two...
