Nitryl fluoride is a chemical compound from the group of fluorides and Nitrylverbindungen. It was first synthesized in 1905 by Henri Moissan in 1929 and first studied by Ruff.

Production and representation

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

A direct reaction of dinitrogen pentoxide with sodium fluoride is possible.

Also possible is the preparation by reaction of nitrogen dioxide with fluorine.

Properties

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

Use

Nitryl fluoride is employed as fluorinating and oxidising agent.
