Quaternary ammonium tribromides and quaternary phosphonium tribromides are recovered from an organic solvent by washing with an aqueous hydrazine solution. The hydrazine reacts to form nitrogen, hydrobromic acid and a quaternary ammonium or quaternary phosphonium monobromide.

The hydrobromic acid can be neutralized with a quaternary ammonium or quaternary phosphonium hydroxide to produce a quaternary ammonium or quaternary phosphonium monobromide. The monobromides produced can be reacted with elemental bromine to regenerate a tribromide brominating agent.
