  CL-20 is the most energetic conventional explosive available for military use. The over all aim of the high energy material research community is to increase the yield and reduce the cost of CL-20 synthesis. All synthetic methods used to prepare the CL-20, depended on the condensation reaction of benzylamine with glyoxal for the preparation of HBIW intermediate . In the presence of HCOOH cata...
