Nitrogen bromid

Under certain circumstances bromine reacts with ammonia and amino compounds to form bromamide [14519-10-9] NH2Br, bromimide [14519-05-0], NHBr2, or nitrogen bromide [15162-90-0], NBr. These compounds can decompose explosively so great care should be exercised any time bromine and ammonia or amino compounds might come in contact with each other. 

By evaporating a mixture of bromine and ammonia at low temperatures, nitrogen bromide [15162-90-0] NBr, is obtained as the ammoniate NBr hNH. This compound decomposes explosively when warmed to room temperature. NH2Br and bromimide [14519-05-0], NHBr2, are formed when bromine reacts with ammonia in ether solution at low temperatures. These products have not been isolated (1).

The reaction is 8NH3+3Br,=6NH4Br+Na. The liquid should remain strongly ammoniacal during the addition of the bromine, and it should be continually shaken. If the bromine is run in too rapidly, or if the liquid becomes acid, the explosive nitrogen bromide may be formed. Heat the liquid nntil all the free ammonia is driven off, and evaporate the soln. to enable the ammonium bromate to crystallize. Dry the aihmonium salt by warming the dish over a flame. The yield is 220 grms. of ammonium bromate. 

It is stable for days at —40°C and is not explosive.72 Nitrogen bromide is similar to NC13. 

Nitrogen bromide—NBr,—264 has been obtained as a reddU brown, syrupy liquid, very volatile, and resembling the chloride in iti propexties, by the action ofjpotassium bromide upon nitrogen chloride. 

Nitrogen bromide, sulfur, and many selenium halides and oxyhalides result in explosive reactions when mixed with white phosphoms (NFPA 1997).
