Application background and overview of nitrate tetrafluoroborate
Nitrafluoroborate can be used to prepare ionic liquids. If tetrafluoroborate nitrate is inhaled, please move the patient to fresh air; if the skin comes into contact, take off contaminated clothing, rinse the skin thoroughly with soap and water, and seek medical treatment if you feel uncomfortable; if the eyes come into contact, separate Rinse the eyelids with running water or saline and seek medical attention immediately. If ingested, rinse mouth immediately. Do not induce vomiting and seek medical attention immediately.
Applications of nitrate tetrafluoroborate
Nitrafluoroborate can be used to prepare an ionic liquid that contains a reagent that increases the oxidizing ability of the liquid, such as oxidizing a non-oxidizing liquid. Thus, the liquid contains not only one anion and one cation, but also another component that enhances the liquid’s ability to react with oxidized substrates. In a preferred embodiment, the liquid contains a mildly oxidizing anion [NO3-] and an acid, which may be a Bronsted acid or a Franklin acid, such as HNO3, H2SO or [NO+], for example from nitrate tetrafluoroborate. Accordingly, the present invention includes ionic liquids capable of oxidizing UO2 to convert uranium to U(VI), especially ionic liquids containing nitrate anions and nitronium, which liquids have oxidizing reactions to various matrices such as UO2 and PuO2 sex.
The concentration of cations is sufficient for the liquid to react with UO2 and oxidize uranium to U(VI). The ionic liquid also contains tetrafluoroborate (I, rubidium carbonate, II) and organic cations. Preferred products are ionic liquids containing [NO+], usually to which [NO][BF4] has been added. The preparation of tetrafluoroborate [NO][BF4][Bu-py][NO3] is as follows: add heavy calcium carbonate to 1-butyl nitrate under stirring. Pyridinium (3.000g, 15.1mmol). The brown smoke evolves immediately and the solution quickly changes to a dark blue/green color. After stirring overnight, all the nitric tetrafluoroborate dissolves, resulting in a blue/green solution with a viscosity much lower than the raw material 1-butylpyridine nitrate.
