Raschig process
Quick Summary
The Raschig process is a chemical method used for the production of hydrazine (N₂H₄). This process involves the oxidation of ammonia using sodium hypochlorite, typically with gelatin or glue as a catalyst to prevent unwanted side reactions. Variations of the process may use urea instead of ammonia. Hydrazine is a powerful reducing agent with various applications, including in the synthesis of pesticides, as a base for blowing agents in foam rubber production, and as a corrosion inhibitor in boilers. It is also used in the manufacture of explosives and agricultural fungicides, and its derivatives serve as rocket fuel.12

ammoniaHydrazine…is best prepared by the Raschig process, which involves the reaction of an aqueous alkaline ammonia solution with sodium hypochlorite (NaOCl). 2NH3 + NaOCl → N2H4 + NaCl + H2O This reaction is known to occur in two main steps. Ammonia reacts rapidly and quantitatively with the hypochlorite ion, OCl−,…
