Abstract

Urotropinium nitrate, N-methylurotropinium azide, dinitramide and azotetrazolate salts have been prepared and fully characterized by analytical and spectoscopic ( 1 H, 13 C, 14 N NMR, IR, Raman) methods. The structures of all four compounds have been determined using X-ray diffraction techniques and represent Synthese, Charakterisierung und Kristallstrukturen von verschiedenen energiereichen Urotropinsalzen mit Azid-, Nitrat-, Dinitramid-und Azotetrazolat-GegenionenInhaltsübersicht. Urotropinnitrat, N-methylurotropinazid, -Dinitramid-und -Azotetrazolat-Salze wurden dargestellt und analytisch und spektroskopisch ( 1 H-, 13 C-, 14 N-NMR, IR, Raman) charakte-

Determination of the Acid-Base Dissociation Constant of Acid-Degradable Hexamethylenetetramine by Capillary Zone Electrophoresis

“…10 An aliquot of 1.00 g hexamine and an equivalent amount of ethyl iodide (0.570 mL) were dissolved in an aliquot of 50 mL of ethanol. The reaction solution was allowed to stand for 24 h at 40 C. After the reaction, the precipitated needle-crystal was filtered and washed with ethanol.…”

“…The slope, 1.03, indicates that the deprotonation reaction is one step (n = 1 in Eqs. (10) and (11)). This result also assures the monoprotic equilibrium of hexamine in this pH range.…”

Comparison of GIAO and CSGT for calculating 13C and 15N nuclear magnetic resonance chemical shifts of substituent neutral 5‐aminotetrazole and 5‐nitrotetrazole compounds

“…These elements combine with practically all other elements of the periodic table. Nitrogen‐rich materials, especially tetrazoles, have great potential for energetic applications …”

Amantadinium azide

“…For general background, see: Anga et al (2002). For related structures, see: Bé langer-Garié py et al (1987); Singh et al (2006); Yang et al (2006).…”

“…Energetic salts often possess many advantages over conventional non-ionic energetic molecular compounds since the salts tend to exhibit lower vapor pressures than their non-ionic analogs. For related structure, urotropine, a model for energetic, nitrogen rich cage compounds, with the azide, has been reported (Anga et al, 2002). There are two distinct hydrogen-bonded rings as a result of that the zide act as a bridge which are quite different from the other amantadinium (Bélanger-Gariépy et al, 1987;Yang et al, 2006).…”
