Web1.1A. MSDS Information. Diazodinitrophenol Usage And Synthesis. General Description. A yellow crystalline solid that darkens on exposure to sunlight. Must be shipped wet with at least 40% water or water and denatured alcohol mixture. May explode due to shock, heat, flame, or friction if dry. May explode under prolonged exposure to heat or fire. WebThe velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density. See also [ edit] TNT equivalent RE factor
