Nitryl fluoride is a chemical compound from the group of nitryl compounds and fluorides . It was first synthesized in 1905 by Henri Moissan and examined for the first time in 1929 by Otto Ruff .

Extraction and presentation

Nitryl fluoride can be obtained through a two-step reaction. First, a solution of nitrous pentoxide in nitromethane is reacted with boron trifluoride and hydrogen fluoride to form nitryl fluoroborate . This reacts at 240 ° C with sodium fluoride to form nitryl fluoride.

${\displaystyle \mathrm {N_{2}O_{5}+BF_{3}+HF\longrightarrow NO_{2}[BF_{4}]+HNO_{3}} }$

${\displaystyle \mathrm {NO_{2}[BF_{4}]+NaF\longrightarrow NO_{2}F+NaBF_{4}} }$

A direct reaction of nitrous oxide with sodium fluoride is also possible.

${\displaystyle \mathrm {N_{2}O_{5}+NaF\longrightarrow NO_{2}F+NaNO_{3}} }$

It is also possible to display it by reacting nitrogen dioxide with fluorine .

${\displaystyle \mathrm {2\ NO_{2}+F_{2}\longrightarrow 2\ NO_{2}F} }$

properties

Bond lengths and angles of nitrile fluoride

Nitryl fluoride is a gas and liquid, colorless, in the solid state white, pungent odor, which is hydrolyzed by water. It reacts with most metals and non-metals, as well as violently with ethanol , ether, benzene and chloroform .

use

Nitryl fluoride is used as a fluorinating and oxidizing agent.
