A PROCESS FOR THE PREPARATION OF 2, 2’4, 4’6, 6’-HEXANITROSTILBENE

摘要

The preparation of HNS is described in the U.S. Patent 3,505,413 According to that process, trinitrotoluene (henceforth referred to as TNT) is dissolved in a mixture of tetrahydrofuran—methanol and this solution is added to an excessive amount of a 5% aqueous solution of sodium hypochlorite. The precipitation of SIS crystals begins within a short period of time, and after the completion of the crystallization the product that has formed is filtered, washed, and dried. In this manner the crude.
