Method of regeneration of azide ion

In this article the results of research devoted to the development of methods of disposal and regeneration of azide ion contained in the liquid wastes are stated. As a rule, all existing methods of disposal of azide ion in the liquid wastes based on its destruction, which is not only economically impractical because it is irretrievably lost, but also dangerous, as this forms an extremely explosive and toxic hydrazoic acid, which significantly increases the risk of the process of disposal of liquid wastes. Researches carried out by the authors allowed for the first time to suggest an effective method of disposal of azide ion at producing organic azides that consists in deletion of azide ion from reaction mass in the form of azide of quaternary ammonium which is highly active azidating agent and can be effectively used in the processes of getting organic azides. In this case at getting organic azides before its finishing quaternary amonium chloride is added to the reaction mass.
