  • Patent number: 4997987
    Abstract: Preparation of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) from 3,5-dichloroanisole. Nitration of 3,5-dichloroanisole under relatively mild conditions gave 3,5-dichloro-2,4,6-trinitroanisole in high yield and purity. Ammonolysis of this latter compound gave the desired TATB. Another route to TATB was through the treatment of the 3,5-dichloro-2,4,6-trinitroanisole with thionyl chloride and dimethylformamide to yield 1,3,5-trichloro-2,4,6-trinitrobenzene. Ammonolysis of this product produced TATB.
    Type: Grant
    Filed: June 8, 1990
    Date of Patent: March 5, 1991
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Donald G. Ott, Theodore M. Benziger

  • Patent number: 4481371
    Abstract: A method of forming a fine-grained species of the insensitive high explosive sym-triaminotrinitrobenzene (TATB) without grinding. In accordance with the method, 1,3,5-trichloro-2,4,6-trinitrobenzene (TCTNB) is aminated by reaction with gaseous ammonia in an emulsion of toluene in water. The ratio of water to toluene in the emulsion is selected so that toluene is the dispersed phase in the emulsion. The size of the dispersed TCTNB-containing toluene droplets determines the particle size of the resulting TATB. The emulsion is preferably formed with an emulsifier such as ammonium oleate, which may be generated in situ from oleic acid, and stabilized with a protective colloid such as polyvinyl alcohol.

    Inventor: Theodore M. Benziger
  • Patent number: 4168191
    Abstract: By use of an appropriate thermoplastic rubber as the binder, the thermal stability and thermal stress characteristics of plastic-bonded explosives may be greatly improved. In particular, an HMX-based explosive composition using an oil-extended styrene-ethylenebutylene-styrene block copolymer as the binder exhibits high explosive energy and thermal stability and good handling safety and physical properties.

    Inventor: Theodore M. Benziger
  • Patent number: 4032377
    Abstract: Triaminotrinitrobenzene is readily formed by the nitration of 1,3,5-trichlorobenzene to 1,3,5-trichloro-2,4,6-trinitrobenzene followed by amination to triaminotrinitrobenzene. The purity of the triaminotrinitrobenzene is significantly improved if, during the amination step, sufficient water is present that the byproduct ammonium chloride formed during the amination is rendered at least semideliquescent.

    Inventor: Theodore M. Benziger
  • Patent number: 3985595
    Abstract: A highly insensitive and heat resistant plastic-bonded explosive containing 90 wt % triaminotrinitrobenzene and 10 wt % of a fully saturated copolymer of chlorotrifluoroethylene and vinylidene fluoride is readily manufactured by the slurry process.
