The glow-discharge electrolysis of electrolyte solutions in liquid ammonia has been investigated over a wide range of conditions. The main product in solution is hydrazine in amount dependent upon the quantity of electricity passed. The yield initially when the glow-discharge electrode is an anode is 2-5 moles/faraday, but it decreases somewhat as hydrazine accumulates in the solution and a stationary concentration of about 2~ is ultimately reached; the hydrazine yield is substantially independent of most other experimental variables. I t is considered that the reactions are initiated by positively charged gaseous ions which are accelerated in the cathode fall near the liquid surface. On entering the liquid phase these are involved in both charge-and energy-transfer reactions producing NH, radicals. The proportions of the products formed are then considered to depend upon the competition of the various possible reactions of these radicals, and on this basis a quantitative interpretation of the results is possible.The latter is a parameter of importance since the concentration of any reactive species formed
