Abstract
L'invention concerne un procédé de production de 4,6-dinitrorésorcinol, qui consiste à faire réagir un 1,3-dihalo-4,6-dinitrobenzène avec une base dans un milieu aqueux, en présence d'un catalyseur métallique, de sorte qu'il soit hydrolysé puis acidifié. Ledit procédé permet la production de 4,6-dinitrirésorcinol de grande pureté, avec un grand pourcentage en volume, de manière sûre, facilement et avec un grand rendement.
