NITRONIUM TETRANITRATE BORATE AND THE PROCESS OF ITS PREPARATION Russian patent published in 2018 - IPC C01B21/82 C01B35/08 C01B35/18

Abstract RU 2654982 C1

FIELD: chemistry.

SUBSTANCE: invention relates to inorganic chemistry and can be used in the development of composite solid rocket fuels (TRT), an oxidizer of liquid rocket fuels. Nitronium tetranitrate borate has the chemical formula NO₂[B(NO₃)₄]. To obtain nitronium tetranitrate borate, boric acid is reacted with N₂O₅ at a temperature of -10 to 5 °C. Process is carried out at a molar ratio of boric acid:N₂O₅ 1:(4–6) using nitric acid and/or an inert solvent, which is used as methylene chloride.

EFFECT: invention allows to obtain a new compound, nitronium tetranitrate borate, which significantly exceeds the oxygen balance of an oxidizing agent such as the ammonium salt of dinitrazoic acid (ADN), does not contain halogens, and has a high thermal stability.
