초록

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...
