Andrussow process

File:1931.01.31 23 Andrussow Pilot Plant Herne Germany.jpg

Late 1930: Semitechnical plant for experiments on the production of hydrogen cyanide with the Andrussow process in Herne, Germany, operated by Leonid Andrussow.

The Andrussow process is an industrial process for the production of hydrogen cyanide from methane and ammonia in the presence of oxygen and a platinum catalyst.^[1]^[2]

CH₄ + NH₃ + 1.5 O₂ → HCN + 3 H₂O

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.
