  • METHOD FOR DETERMINING THE SENSITIVE OR INSENSITIVE NATURE OF A HEXOGEN
    Publication number: 20100258223
    Abstract: The present invention relates to a process for determining the sensitive or insensitive nature of a crystalline hexogen. Said process comprises: the formulation of said crystalline hexogen in a matrix; the analysis of a sample of said matrix charged with said crystalline hexogen by differential scanning calorimetry; said matrix consisting essentially of at least one liquid polymer that is suitable for the formulation of binders for energetic materials charged with nitro organic explosives; and of at least one adsorbent for the volatile organic compounds, which is stable at the operating temperature of the analysis and which has low affinity for water. The present invention also relates to the crystalline hexogen in such a matrix.

  • Process for the synthesis of 2,4,6,8-tetranitro-2,4,6,8-tetraazabicyclo (3.3.0) octane
    Patent number: 5659032
    Abstract: The invention relates to a new process for the synthesis of 2,4,6,8-tetranitro-2,4,6,8-tetraazabicyclo-[3.3.0]octane (bicyclo-HMX) by reaction of nitronium tetrafluoroborate with 2,4,6,8-tetraacetyl-2,4,6,8-tetraazabicyclo[3.3.0]octane in the presence of fluoride ions.The process makes it possible to obtain pure bicyclo-HMX in an acceptable yield.Bicyclo-HMX is an explosive which can be employed as explosive or propellent charge in solid pyrotechnic compositions.
