Abstract

Procédé de préparation de l'hexanitro-2,2', 4,4', 6,6' stilbène. On fait réagir un hypochlorite de métal alcalin ou alcalino-terreux 3 avec du trinitro-2,4,6 toluène 2 dans un solvant organique ; on laisse le mélange réactionnel reposer pendant au moins 30 minutes puis on ajoute une solution d'acide minéral 7 en agitant pour acidifier le mélange à un pH final inférieur à 5; on laisse le mélange sédimenter et se séparer en deux couches et l'on fait passer la couche inférieure à travers le filtre 12. Application à l'obtention d'hexanitrostilbène ayant une surface spécifique comprise entre 3 et 6 m**2 . g**-1 (selon les techniques d'adsorption gazeuse).
