Two new polyacylhexaazaisowurtzitanes were synthesized. Pentaacetyl- or pentaacetylformylhexaazaisowurtzitane can be a precursor in the preparation of HNIW, recently developed highly energetic material.
Synthesis and scale-up of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane from 2,6,8,12-tetraacetyl-4,10-dibenzyl-2,4,6,8,10,12-hexaazaisowurtzitane (HNIW, CL-20)

The invention discloses a method for preparing CL-20 through a two-step method, and belongs to the technical field of energetic materials. The method includes the steps of firstly, adding a sulfamatewater solution and a 40% glyoxal water solution into a container, conducting the condensation reaction at a certain temperature, and then conducting filtering and drying to obtain white powder HSIW; secondly, conducting nitration reaction on the HSIW obtained in the first step through a nitrating agent, pouring nitration liquid into icy water, and conducting filtering, washing and drying to obtaina product containing CL-20, wherein the yield of the CL-20 can reach 1.78% at most. By means of the method, sulfamate replaces benzylamine, and the raw material cost is reduced; no catalytic hydrogenolysis is needed, and cost is reduced; the preparing process of the CL-20 is simplified, and the synthesis cycle of the CL-20 is shortened.
