Abstract
THE various hydrides and oxides of nitrogen comprise the subject matter of parts 2 and 3 of the volume on nitrogen, but aqueous solutions of ammonia and the oxy-acids are not included. Prominence is given to the preparation of the raw materials used in the industrial synthesis of ammonia. It is pointed out that nitrogen extracted from air is very much cheaper than hydrogen, which comes chiefly from water-gas (51.8 per cent), coke-oven gas (30 per cent) and electrolytic plants (16.67 per cent). The Linde, Claude and Messer processes for extracting hydrogen from coke-oven gas are given very fully, as well as the synthesis of ammonia by the Haber-Bosch, Claude, Fauser and Mont Cenis methods. There is also an account of heavy ammonia, ND3, which has been obtained pure by the action of deuterium oxide on magnesium nitride.
