A process and an apparatus for electrochemical decomposition of sodium azide in aqueous alkaline solutions form sodium hydroxide, ammonia, nitrogen, and oxygen. The apparatus contains five major parts, which are (1) an electrolyzer which contains one or more cell units, (2) a rectifier which supplies D.C. electrical current to the electrolyzer, (3) a tank which holds the electrolyte (containing sodium hydroxide and sodium azide) needed to be processed in the electrolyzer, (4) a vacuum which can remove off gases generated by electrolysis in the electrolyz...
[ What is claimed is:] [1.] A process for decomposing sodium azide comprisingelectrolyzing sodium azide present in an aqueous alkaline solution to decompose said sodium azide to form a resulting aqueous alkaline solution having a reduced amount of sodium azide,wherein said process results in an overall chemical reaction comprising NaN.sub.3 +2H.sub.2 O.fwdarw.NaOH+NH.sub.3 +N.sub.2 +1/2O.sub.2.
