METHOD FOR OBTAINING 4,10-DIFORMYL-2,6,8,12-TETRAACETYL-2,4,6,8,10,12-HEXAAZATETRACYCLO[5,5,0,0,0]DODECANE Russian patent published in 2022 - IPC C07D487/22

Abstract RU 2772755 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing 4,10-diformyl-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,0^3.11,0^5.9] dodecane (DF), which includes the hydrogenolysis of 4,10-dibenzyl-2,6,8,12-tetraacetyl-2,4,6,8,10,12-hexaazatetracyclo[5,5,0,0^3.11,0^5.9]dodecane (DB) in a formic acid medium with the addition of water, in a hydrogen atmosphere, in the presence of a palladium catalyst, under a pressure above atmospheric, at a temperature of 55-65°C for 2.5-3.5 hours.

EFFECT: developed a method for obtaining DF used for the synthesis of a highly effective explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20), which makes it possible to reduce the duration of the process while maintaining output of the target product.
