nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °c. the reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). the difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. it was found that both the yield and purity of the product is better starting with potassium sulp...

High nitrogen energetic materials with astonishing thermal behaviors and performances were synthesized by different metathesis reactions. Particularly the new compound triaminoguanidinium 1-methyl-5-nitriminotetrazolate (TAG-1-Me-AtNO2, 4) shows great explosion performance and may be an alternative to commonly used and toxic RDX. An improved synthesis for the promising energetic compound 4 is a...

A T-jump/time-of-flight mass spectrometer (T-Jump/TOFMS) is used to probe the decomposition of several aminotetrazole containing energetic materials under very high heating rates of 10(5)-10(6) K/s. The materials investigated are 5-amino-1-methyl-1H-tetrazolium dinitramide (MeHAT_DN), 1,5-diamino-4-methyl-1H-tetrazolium dinitramide (MeDAT_DN), 1,5-diamino-1H-tetrazolium nitrate (DAT_N), 1,5-dia...

N-Guanylurea-dinitramide (FOX-12) is a very insensitive energetic material intended to be used in the composition of next-generation insensitive munitions. To help predict the environmental behavior and fate of FOX-12, we conducted a study to determine its photodegradability and biodegradability. When dissolved in water, FOX-12, a guanylurea-dinitramide salt, also named GUDN, dissociated instan...

The crystal structure of solvate-free silver dinitramide (Ag[N(NO(2))(2)]) was determined by X-ray diffraction for the first time and displays secondary contacts between silver and oxygen as well as between silver and nitrogen, furnishing different coordination modes of the dinitramide moiety.

New energetic polyazole polynitrobenzenes exhibit high heats of formation and thermal stabilities, and react as useful ligands with silver dinitramide to give an energetic coordination complex.

Recently there has been increased interest in high nitrogen content “green” energetic materials which are designed to produce relatively non-toxic decomposition products as part of a push to decrease the environmental impact of energetic materials through all phases of their existence. With the use of a T-Jump/Time-of-Flight Mass Spectrometer (T-Jump/TOFMS) capable of high heating rates (up to ...
