Reakcja fenolu z mieszaniną nitrującą prowadzi do powstania ciemnego wielkocząsteczkowego produktu utleniania, a nie kwasu pikrynowego. Typową metodą otrzymywania kwasu pikrynowego jest nitrowanie kwasu p-hydroksybenzenosulfonowego, otrzymywanego przez sulfonowanie fenolu.Inne sposoby to np. reakcja benzenu z 1,6% roztworem azotanu rtęci(II) w ~65% kwasie azotowym lub alkaliczna ...

picric acid, pale yellow, odourless crystalline solid that has been used as a military explosive, as a yellow dye, and as an antiseptic. Picric acid (from Greek pikros, “bitter”) was so named by the 19th-century French chemist Jean-Baptiste-André Dumas because of the extremely bitter taste of its yellow aqueous solution.
Picric acid is a chemical compound used as an explosive material and precursor for other explosives. Learn about its toxicokinetics, uses, and thermal decomposition mechanisms from various chapters and articles on ScienceDirect.
7 lis 2024 · Picric acid’s biggest failing was its instability; it posed a constant risk when handled. But its explosive power—10 times that of dynamite—overwhelmed such concerns. By the late 1800s it was the shell filling of choice for artilleries across the globe under different names and in slightly different formulations—Mélinite in France ...
Picric acid is a poisonous, trinitroaromatic compound that is a flammable solid when purchased wet. Picric acid is a high-powered explosive when allowed to dehydrate. As an explosive, picric acid is not shock sensitive, but when in contact with metals, it can form shock sensitive metal picrates.
