Nitrosyl bromide is a chemical compound from the group of nitrosyl compounds .

Extraction and presentation

Nitrosyl bromide can be produced by the reaction of potassium bromide with nitrogen dioxide

${\displaystyle \mathrm {2\ NO_{2}+KBr\longrightarrow NOBr+KNO_{3}} }$

or by reacting nitrogen monoxide with bromine at temperatures below 0 ° C.

${\displaystyle \mathrm {2\ NO+Br_{2}\longrightarrow 2\ NOBr} }$

properties

Nitrosyl bromide is a dark brown liquid or red gas that has a strong oxidizing and corrosive effect. At room temperature it partially dissociates to form bromine and nitrogen monoxide.
