  • Patent number: 8658818
    Abstract: Methods of forming a nitrate ester include combining at least one nitrate salt and sulfuric acid to form a nitrating solution and adding an aliphatic polyol to the nitrating solution. Nitrate esters formed by this method may be, for example, triethylene glycol dinitrate (TEGDN), pentaerythritol tetranitrate (PETN), diglycerol tetranitrate (DGTN), 1,1,1-tris(methylol)ethane trinitrate (TMETN), 1,2,4-butanetriol trinitrate (BTTN), nitroglycerin (NG), diethylene glycol dinitrate (DEGDN), ethylene glycol dinitrate (EGDN), metriol trinitrate (MTN), nitrocellulose (NC), or 1,2-propanediol dinitrate (PDDN).

  • Patent number: 8471041
    Abstract: A method of synthesizing and isolating N-(bromoacetyl)-3,3-dinitroazetidine (ABDNAZ) by reacting DNAZ with bromoacetyl bromide and boron trifluoride etherate to produce a mixture comprising ABDNAZ and a salt of DNAZ. Water and a solvent are added to the mixture to form an organic phase comprising the ABDNAZ and an aqueous phase comprising the salt of DNAZ. The organic phase and the aqueous phase are separated to produce an ABDNAZ/solvent solution comprising the ABDNAZ and the aqueous phase comprising the salt of DNAZ. A nonsolvent is added to the ABDNAZ/solvent solution to produce an ABDNAZ/solvent/nonsolvent mixture. The ABDNAZ is subsequently recovered. A composition comprising ABDNAZ is also disclosed.

  • Patent number: 7910776
    Abstract: Methods of producing 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), from alkoxy derivatives of phloroglucinol, such as 5-methoxyresorcinol, 3,5-dimethoxyphenol, or 1,3,5-trimethoxybenzene, are disclosed. The alkoxy derivatives may be exposed to and directly nitrated with a reaction mixture comprising a sulfuric acid solution and at least one nitrate salt. The nitrated alkoxy derivative of phloroglucinol may be alkoxylated and, thereafter, aminated to produce the TATB.

  • Patent number: 7737308
    Abstract: Methods of nitrating compounds, such as phloroglucinol or a methoxy derivative thereof, are disclosed. For example, a reaction mixture may be formed by combining sulfuric acid and at least one nitrate salt. A nitratable aromatic compound, such as phloroglucinol or a methoxy derivative thereof, may then be exposed to the reaction mixture to nitrate the phloroglucinol or methoxy derivative thereof.
