Hyponitrites were first prepared in 1871 by Edward Divers by reducing an alkaline nitrate in water solution by means of sodium amalgam. About seven years later A. E. Menke, of Kings College, London, obtained a compound by heating cast iron filings with sodium nitrate which Professor Bloxam suggested to be the compound discovered by Dr. Divers. An analysis of the sodium determined as sodium sulphate and an analysis of the nitrogen determined as ammonia yielded the theoretical amounts of these elements, all within the limits of experimental error. On drying at 100° C. it lost in weight corresponding to three molecules of water of crystallization. He also prepared the silver salt and analyzed it, and the results corresponded to theory.
