Olin Raschig process
From Wikipedia, the free encyclopedia
The Olin Raschig process is an industrial process used to produce hydrazine and developed by the Olin Corporation. Sodium hypochlorite solution is mixed with ammonia at 5 °C to form chloramine and sodium hydroxide, which is then rapidly added to anhydrous ammonia under pressure and heated to 130 °C to generate hydrazine, water and sodium chloride (waste product). Ammonia is used in a 33 fold excess.
