The invention is an article of manufacture, a composition of matter and an in-situ process for making non-hygroscopic ammonium nitrate prills. The non-hygroscopic prills are formed from dried prills of ammonium nitrate, in reaction vessel having an inert gas atmosphere and a nonpolar reaction diluent. A shell is formed in situ by reacting a first reactant with a second reactant in the presence of the AN prills en masse. The prills, en masse, are individually sealed in the shell made of a highly crosslinked polymeric material. The material is a reaction product of a diglycidyl hydantoin and a polyoxypropylene-triamine.

Ammonium nitrate prill having a non-hygroscopic shell

The present disclosure relates generally to a critical intermediate in a synthesis of a postulated energetic material, and more specifically relates to a critical intermediate, 3,5-diamino-2,6-di-(tert-butyl-NNO-azoxy)pyrazine, having the structure: The postulated energetic material has calculated performance properties that greatly exceed those of HMX and CL-20. The specific critical intermediate (Compound 1) shown above has a molecular weight of 310.359 g/mol, a density at &#x2212;123&#xb0; C. of 1.293 g/mL, and a density at 20&#xb0; C. of 1.259 g/mL.
