Process for preparing hexanitrobibenzyl

摘要

2,2', 4,4', 6,6'-hexanitrobibenzyl, an intermediate compound used for making hexanitrostilbene, is prepared by dissolving trinitrotoluene in a solvent system comprising a water-immiscible solvent and an aliphatic alcohol and then adding a metal hypochlorite solution containing a metal hydroxide to the trinitrotoluene solution to form the hexanitrobibenzyl. The compound is then separated from the reaction mixture.
