Abstract

A process for the preparation of 2, 2',4,4',6,6'-hexanitrostilbene comprises the steps of:- a. reacting an alkali or alkaline earth metal hypochlorite with 2,4,6-trinitrotoluene in an aqueous organic solvent; b. allowing said reactant mixture to stand for a period of at least 30 minutes; c. after said standing period, adding a solution of a mineral acid, with stirring, to said reactant mixture to acidify said mixture to a final pH of less than 5, so as to cause agglomeration of the hexanitrostilbene; d. allowing the mixture obtained in step c. to settle and separate into two layers; e. passing at least the lower of said two layers through a filter to filter off the suspended product. Washing the product afforded hexanitrostilbene that has a surface area of between 3 and 6 metre<2>gm<-1> when measured by gas adsorption techniques.
