Tetrafluoroammonium

K [14881-07-3], Rb [72151 -96-3], and Cs [72138-72-8]), are prepared by reaction of elemental fluorine, chlorine trifluoride, or xenon difluoride and a mixture of nickel fluoride and alkaH metal fluorides or other metal haHdes (16,17). If the fluorination is carried out using mixed fluorides, a lower temperature can be used, yields are quantitative, and the final products are of high purity. Bis(tetrafluoroammonium) hexafluoronickelate [6310540-8], (NE 2N iF6> prepared from Cs2NiF3 and NE SbE by a metathesis in anhydrous HE, is also known (18). [Pg.214]

The pure liquid explodes on freezing at — 167°C, and the gas is readily initiated by sparks, flame or contact with grease, dust or rubber tubing. Contact of the gas with aqueous potassium iodide also caused an explosion [1], The pure material is now readily accessible via the relatively stable intermediate, tetrafluoroammonium perchlorate [2],...

Tetrafluoroammonium salts hydrolyze in water, regenerating NF3. Nitrogen trifluoride reacts with several metals at high temperatures. When heated with copper, it yields copper(ll) fluoride and dinitrogen tetrafluoride ... [Pg.656]

The tetrafluoroammonium cation (NF/) has high electronegativity (the oxidation number of nitrogen is + 5) and high kinetic stability (NF4+ is isoelectronic with CF4).15 -17 It has been shown that in anhydrous hydrogen fluoride, benzene and its derivatives are fluorinated by tetrafluoroammonium tetrafluoroborate with substitution of hydrogen by fluorine.15-17...
