  • Patent number: 10336662
    Abstract: 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.
