  • COLORIMETRIC DETECTION OF ENERGETIC MATERIALS
    Publication number: 20200158652
    Abstract: Exemplary systems for detecting energetic materials include: a sample wipe comprising a fibrous substrate configured to absorb and/or adhere to the energetic material; means for applying at least a first reagent configured to produce a visible color upon reaction with the energetic material to the sample wipe; means for applying at least a second reagent configured to produce a second visible color upon reaction with the energetic material to the sample wipe; and means for applying at least one solvent configured to solvate the energetic material to the sample wipe. Sample wipes may also be used independently to detect energetic materials, and include: a fibrous substrate configured to absorb/adhere to an energetic material; and a solvent configured to solvate the energetic material. Methods for detecting presence of energetic materials in a sample are also disclosed.

  • Synthesis of an azido energetic alcohol
    Patent number: 8841468
    Abstract: A method of forming an azido energetic alcohol includes converting an energetic diol to a cyclic sulfite, oxidizing the cyclic sulfite to a cyclic sulfate, and opening the cyclic sulfate. The cyclic sulfate is opened, followed by hydrolysis, to form an azido energetic alcohol.
