  • Thermally stable booster explosive and process for manufacture
    Patent number: 7192497
    Abstract: A thermally stable booster explosive and process for the manufacture of the explosive. The product explosive is 2,4,7,9-tetranitro-10H-benzo[4,5]furo[3,2-b]indole (TNBFI). A reactant/solvent such as n-methylpyrrolidone (NMP) or dimethyl formamide (DMF) is made slightly basic. The solution is heated to reduce the water content. The solution is cooled and hexanitrostilbene is added. The solution is heated to a predetermined temperature for a specific time period, cooled, and the product is collected by filtration.
    Type: Grant
    Filed: December 16, 2005
    Date of Patent: March 20, 2007
    Assignee: BWXT Pantex LLC

  • Continuous aspiration process for manufacture of ultra-fine particle HNS
    Patent number: 6844473
    Abstract: A process for the manufacture of ultra-fine-particle hexanitrostilbene (HNS). Hexanitrostilbene is mixed in n-methylpyrrolidone (NMP) and the solution is steam heated for approximately one hour. The solution is rapidly mixed with cold water by means of drawing it through an aspirator through which water is flowing. The produced slurry is captured in a receiver and then filtered through a 0.45-micron filter. The recovered HNS product is then freeze dried.
