With respect to high-energy dense materials with high oxygen-content, the tetrasodium salt of 1,1,2,2-tetranitraminoethane as monohydrate Na4TNAE·H2O (4) and the tetrapotassium salt as dihydrate K4TNAE·2H2O (5) were synthesized and reported for the first time together with their crystal structures at 173 K. Whilst 4 cannot be dehydrated the crystal water content of 5 can be removed irreversibly at 160 °C to obtain K4TNAE (6) as demonstrated by DTA and TGA measurements. K4TNAE (6) was demonstrated using the small scale reactivity test to be a inferior explosive to RDX and CL-20. However the anionic nitramine compound was measured to be less toxic against Vibrio fischeri than RDX (EC50: 240 mg·L–1) with respect to its EC50value above 15070 mg·L–1. This demonstrates that the introduction of anionic nitramine moieties is a promising concept for the stabilization of energetic materials with lower toxicity.

The invention relates to alkali metal salt of tetranitroguanamine ethane, a preparation method of the alkali metal salt and a high-energy material, and belongs to the field of a high-energy compound.The preparation method of the alkali metal salt of the tetranitroguanamine ethane comprises: synthesizing a hydrolysis material tetranitroglycoluril; by using a glycoluril as a raw material, using transition metal salt as a catalyst and using acetic anhydride as a water absorbent, performing a nitration reaction under the condition that a temperature is lower than 10 DEG C. The alkali metal salt is low in raw material cost, high in yield and convenient, efficienct and safe in synthesis process. The alkali metal salt of the tetranitroguanamine ethane is prepared according to the preparation method. The alkali metal salt of the tetranitroguanamine ethane is high in purity, high in thermal stability and high in detonation velocity and has no serious hardening phenomenon. The high-energy material comprises the alkali metal salt of the tetranitroguanamine ethane. The high-energy material is high in stability, high in detonation velocity and good in using effect.

Paragraph 0044, (2016/04/22)
A spherical morphology of the high explosive tetranitroglycoluril (TNGU) has been discovered. This new morphology exhibits approximately a twofold improvement in the response of the material to impact, more than a one and a half fold improvement in friction and the same high resistance to electrostatic discharge over non-spherical TNGU produced by other methods.

, p. 465 - 469 (2007/10/02)
A procedure for preparing nitro and nitroacetyl derivatives of glycoluril is described, starting from tetraacetylglycoluril (TAGU).The method proceeds by nitrodeacetylation and (or) hydrolysis.New compounds have been prepared : mononitrodiacetylglycoluril (MONDAGU), dinitrodiacetylglycoluril (DINDAGU) and mononitroglycoluril (MONGU).A general synthetic scheme is proposed and discussed.Some properties of the new derivatives are presented.
