A New Synthetic Approach toward Hexogen
Abstract:
Acetonitrile-trioxymethylene was chosen to replace acetamide-paraformaldehyde for the synthesis of the intermediate hexahydro-1,3,5-triacetyl-s-triazine (TRAT),which was then nitrated by dinitrogen pentroxide to form hexogen(RDX). Under optimized synthetic conditions,a 95.2% yield of TRAT could be attained when the molar ratio of 1,3,5-trioxane to acetonitrile was 1:2,the molar ratio of H2SO4 to 1,3,5trioxane was 1:7.5,the reaction temperature was 75℃,the reaction time was 3 h, H2SO4 was chosen as catalyst and acetonitrile was used as both reactant and solvent.In the subsequent nitration process,carried at 45℃ for 1 h,a 87.2% yield of RDX could be achieved when the molar ratios of TRAT to N2O5 and N2O5 to HNO3 were 1:7 and 1:6,respectively. The overall yield of RDX was 83.0% for this new approach. This established method might be scaled up for industrial productions of RDX due to its simpleness in terms of post treatment and environmental benign.
