The Andrussow process is the dominant industrial process for the production of hydrogen cyanide. [1] It involves the reaction of methane, ammonia, and oxygen. The process is catalyzed by a platinum- rhodium alloy. [2]
Hydrogen cyanide is highly valued for the production or acrylonitrile and adiponitrile, as well as alkali metal salts such as potassium cyanide. [1]
This reaction is very exothermic. The change of enthalpy of this reaction is equal to -481.06 kJ. [3] The heat provided by the main reaction serves as a catalyst for other side reactions.
These side reactions can be minimized by only short exposures to the catalyst of the order of 0.0003 s. [4]
The process is based on a reaction that was discovered by Leonid Andrussow in 1927. In the following years he developed the process that is named after him. HCN is also produced in the BMA process. [5] [6]
