Mono amine and diamine derivatives of cl-20

Abstract

The invention describes the synthesis of novel mono-amine and di-amine derivatives of hexa-nitro-hexaazaisohexawurtzitane (CL-20). The synthesis is effected by the novel use of fluoroacylating compounds to protect the secondary amine groups of acylated precursors to CL-20 against nitrolysis. In so doing the mono-amine and di-amine derivatives of CL-20 are rendered and which in turn may be subsequently utilised as intermediates to generate further novel derivatives with differing physical and chemical properties to the parent compound. Formula (I), wherein:- X=H, and Y=H or NO2.

Description

technical field [0001] The present invention relates to the synthesis of CL-20 derivatives. Background technique [0002] The explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane, known as CL-20, is a explosives, but it is too sensitive for some applications. In its pure form it is very susceptible to damage and fragmentation, releasing CL-20 powder and dust which may cause an accidental explosion. [0003] To reduce the likelihood of such incidents, the crystals of the explosive are coated with a binder. The binder makes it possible to shape the explosive composition into the desired shape, thereby reducing sensitivity. However, in some cases, the interaction between the explosive and the binder was weak and the coating was easily detached from the CL-20 crystals. [0004] One solution is to mix CL-20 with a less sensitive but still explosive compound to reduce the sensitivity of the mixture. CL-20 has been mixed with dinitrotetraoxadiazacyclododecane (...
