BORON-FLUORIDE-CONTAINING ENERGY-INTENSIVE COMPOSITION FOR ENERGY CONDENSED SYSTEMS AND METHOD OF ITS PRODUCTION Russian patent published in 2017 - IPC C06B27/00 C06D5/00 

FIELD: chemistry.

SUBSTANCE: invention relates to boron-fluoride-containing compositions that can be used as high-calorie components of energy condensed systems (ECS), for example, powders, pyrotechnic and explosive compositions, mixed solid rocket fuels, and the like. The boron-fluoride-containing energy-intensive composition for energy condensed systems contains dodecahydro-closo-dodecaborate of chitosan (C₆O₄H₉NH₃)₂B₁₂H₁₂and as an oxygen oxidant, chitosan C₆O₄H₉NH₃ClO₄ and further comprises ultrafine polytetrafluoroethylene (UPTFE) in an amount providing the completeness and rate of boron transfer of the borohydride compound to boron oxofluoride (BOF)₃. The composition is prepared by mixing freshly precipitated, moist dodecahydro-closo-dodecaborate of chitosan, an aqueous gel of chitosan and UPTHE in the form of ethanol dispersion in an appropriate amount to a homogeneous gel, thus the optimal molar ratio of dodecahydro-closo-dodecaborate of chitosan: chitosan perchlorate: UPTFE is 1:1:3.

EFFECT: invention provides for obtaining homogeneous boron-fluoride-containing energy-intensive compositions that are distinguished by the completeness of combustion and are promising for their use as high-calorie components of energy compensated systems.
