  • Patent number: 7763753
    Abstract: Methods of producing 1,3,5-triamino-2,4,6-trinitrobenzene are disclosed. One method comprises dissolving a 1,3,5-trialkoxy-2,4,6-trinitrobenzene compound in an organic solvent to form a 1,3,5-trialkoxy-2,4,6-trinitrobenzene compound solution. The 1,3,5-trialkoxy-2,4,6-trinitrobenzene compound solution is heated to a temperature of from approximately 30° C. to approximately 110° C. The 1,3,5-trialkoxy-2,4,6-trinitrobenzene compound is reacted with an aminating agent at a pressure of from approximately 30 pounds per square inch to approximately 120 pounds per square inch to produce a 1,3,5-triamino-2,4,6-trinitrobenzene solution.

  • Patent number: 7714078
    Abstract: A method is provided in which PGN is end-modified in a process using a single solvent. The resulting end-modified PGN may be stably crosslinked using aliphatic polyisocyanates. Further provided are methods of producing energetic compositions comprising PGN which has been end-modified in a process using a single solvent. Such energetic compositions may be stably crosslinked using aliphatic polyisocyanates.
