  • Process for synthesis of dinitrotetraoxadiazaisowurzitane (DTIW)
    Publication number: 20050261494
    Abstract: A process for producing dinitrotetraoxadiazaisowurzitane (DTIW), including the steps of: (a) introducing a solid material including 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine (THDFP) and a nitrating acid to a reaction vessel, and (b) reacting the THDFP with the nitrating acid in a reaction stage so as to form a solid product containing DTIW, wherein the nitrating acid includes nitric acid and sulfuric acid, and wherein a weight fraction of the nitric acid in the nitrating acid is within a range of 0.40 to 0.55, a weight fraction of the sulfuric acid is within a range of 0.60 to 0.45, and a weight fraction of water in the nitrating acid, with respect to the nitric and sulfuric acids, is less than 0.015.
