Synthesis, characterization and thermal studies of 2-oxo-1,3,5-trinitro-1,3,5-triazacyclohexane (Keto-RDX or K-6)

Synthesis and characterization of spherical 2-diazo-4,6-dinitrophenol (DDNP)

“…The structural features of spherical DDNP were confirmed by 8400S (Japan) infra red spectrophotometer (IR), using KBr pellets. The purity of the DDNP was determined by LC3000 high performance liquid chromatography (HPLC) with C18 column, and mobile phase consists of methanol-water (50:50) at a flow rate of 1 L/min with UV detector at 254 nm [11]. Bulk density of the DDNP was measured by following standard procedure: measuring of volume of given mass sample.…”

Nanostructuring of Pure and Composite‐Based K6 Formulations with Low Sensitivities

“…This result, in accord with Sikder at al. [21], shows one more time the specific high interest to desensitize K6. Therefore aK 6a nd RDX mixed solution (processed via SFE) was investigated within the following section.…”

“…The decomposition peak of n-K6 showsamaximum at 175 8C, whereas smm-K6 provides am aximum at 187 8C. As observed before, whend ecreasing the particles size of energetic materials, the decomposition temperature decreases [ 28,29].T he latter can be easily explainedb y ah ighers urface to volumer atio of smaller particles and the linked chemical and physical activity of molecules/ atoms at the surfaceo ft he particles in contrast to decreasedactivityofatoms insidethe volume.Energy evolved ) [ 21].I nt his work Sikder et al prepared m-sized materialf rom ab atch process and claim K6 as the most powerful energetic material among nitrourea explosives that only can be used in phlegmatized version.…”

“…Structurally similar to the well-knownR DX, which is 1,3,5-trinitroperhydro-1,3,5-triazine (see Figure 1). K6 appears to be an interesting explosive considering its several physical properties and thermalc haracteristics, like 4% more enthalpy of reaction than HMX (at early times of reaction and at the same relatived ensity) [21,22].M oreover,i t can be preparedf rom cost-effective starting materials. However,its main drawback is ah igh sensitivity,p articularly in terms of impact sensitivity (< 1.56 J).…”

A Theoretical Investigation of Potential High Energy Density Compounds of Keto RDX Derivatives with -NO2 and -F Groups

“…There are wide variety species of HEDCs however, each has its own advantages and disadvantages. To brief, though TNGU, and keto RDX 8 possess superior detonation properties, has poor stability in moisture due to the carbonyl groups at the end of the molecules. On the other hand, N-containing cyclic and heterocyclic structures are the traditional sources of energetic materials.…”
