Investigate some factors affecting the synthesis yield of 2,6,8,12-tetraacetyl-4,10-dibenzyl -2,4,6,8,10,12-hexaazaisowurtzitane (TADBIW) used to make CL-20 explosive

Abstract

 TADBIW is the raw material used to synthesize CL-20 explosive (an important energy additive in the production of mixed solid missile fuel. This paper presents the synthesis of TADBIW in two steps: Step 1- Synthesis of hexabenzyl-hexaazaisowurtzitan (HBIW) from glyoxal and benzylamine; Step 2- Synthesize TADBIW from HBIW by acetylation reaction using catalyst Pd(OH)₂/C, H₂. The structure of TADBIW has been studied by spectroscopic techniques FT-IR, ¹HNMR, EDX. Several factors affecting the yield of the synthesis have been evaluated. Experimental results show that with catalyst used Pd(OH)₂/C (10% Pd), H₂ at atmospheric pressure, ethyl acetate as solvent, reaction time 20 hours, reaction efficiency reached 31.8%.
