Ostwald process - Ostwald method
|
This is an industrial method for producing nitric acid by oxidation of ammonia. It was invented by FW Ostwald. A mixture of ammonia and air is reacted at high temperatures over a platinum or platinum-rhodium catalyst to produce nitrogen oxide NO, which is then oxidized at low temperatures to nitrogen dioxide NO2 , which is then absorbed in water to produce nitric acid. Currently, most nitric acid is produced using this method. → Related article Ostwald Source : Heibonsha Encyclopedia About MyPedia Information |
