  • Methods of using ionic liquids having a fluoride anion as solvents
    Patent number: 8071813
    Abstract: A method in one embodiment includes contacting a strongly hydrogen bonded organic material with an ionic liquid having a fluoride anion for solubilizing the strongly hydrogen bonded organic material; and maintaining the ionic liquid at a temperature of about 90° C. or less during the contacting. A method in another embodiment includes contacting a strongly hydrogen bonded organic material with an ionic liquid having an acetate or formate anion for solubilizing the strongly hydrogen bonded organic material; and maintaining the ionic liquid at a temperature of less than about 90° C. during the contacting.

  • Spot test kit for explosives detection
    Publication number: 20060216833
    Abstract: An explosion tester system comprising a body, a lateral flow membrane swab unit adapted to be removeably connected to the body, a first explosives detecting reagent, a first reagent holder and dispenser operatively connected to the body, the first reagent holder and dispenser containing the first explosives detecting reagent and positioned to deliver the first explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body, a second explosives detecting reagent, and a second reagent holder and dispenser operatively connected to the body, the second reagent holder and dispenser containing the second explosives detecting reagent and positioned to deliver the second explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body.

  • Synthesis of trinitrophloroglucinol and triaminotrinitrobenzene (TATB)
    Publication number: 20050070743
    Abstract: A method to convert surplus nitroarene explosives into trinitrophloroglucinol and triaminotrinitrobenzene (TATB) is described. Picric acid is directly aminated to diaminopicric acid, which is converted to trinitrophloroglucinol and triaminotrinitrobenzene.

  • Synthesis and purification of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB)
    Publication number: 20050038297
    Abstract: A method to convert surplus nitroarene explosives (picric acid, ammonium picrate,) into TATB is described. The process comprises three major steps: conversion of picric acid/ammonium picrate into picramide; conversion of picramide to TATB through vicarious nucleophilic substitution (VNS) of hydrogen chemistry; and purification of TATB.
