Nitrogen tribromide is a chemical compound that belongs to the group of nitrogen halides . Due to its sensitivity and high explosiveness, there is no practical application for the connection.

Occurrence

If bromine is used instead of chlorine to disinfect swimming pools , the reaction with urea can produce nitrogen tribromide as a by-product from human excretions.

Extraction and presentation

Nitrogen tribromide can be obtained by bromination of nitrogen trichloride

or by reacting ammonium bromide , sodium chlorite and iron (III) bromide

or by reaction of bis (trimethylsilyl) bromoamine with bromine chloride at -85 ° C in n-pentane as solvent

Nitrogen tribromide can also be produced by electrolysis of an ammonium iodide and potassium bromide solution (NH 4 I + KBr).

In the explosion, nitrogen tribromide breaks down into the elements:
