Tetraacetyldibenzylhexaazaisowutzitane (TADBIW) was the debenzylation compound of hydrogenolysis of hexabenzylhexaazaisowurtzitane (HBIW). Triacetyltribenzylhexaazaisowurtzitane (TATBIW) was the partial debenzylation compound of hydrogenolysis of HBIW. The influence of TATBIW on the hydrogenolysis of TADBIW were studied. Results show that TATBIW is less stable than TADBIW and easily decomposes in formic acid, and its by-products inhibit the hydrogenolysis of TATBIW. The amount of catalyst is increased to 1%, the final product triacetyltriformylhexaazaisowurtzitane (TATFIW) is obtained.
