Andrussow process
open-in-new
<p>The Andrussow process is the dominant industrial process for the production of <a href="/facts/Hydrogen_cyanide/vNtA0Mxe">hydrogen cyanide</a>. It involves the reaction of <a href="/facts/Methane/kBHneYnh">methane</a>, <a href="/facts/Ammonia/MtLtJFtz">ammonia</a>, and <a href="/facts/Oxygen/acyn6o8r">oxygen</a>. The process is <a href="/facts/Catalyst/LPBS7TQC">catalyzed</a> by a <a href="/facts/Platinum/qJC6lQf7">platinum</a>-<a href="/facts/Rhodium/xmBd9aFG">rhodium</a> alloy. </p> 2 CH4 + 2 NH3 + 3 O2 → 2 HCN + 6 H2O <p>Hydrogen cyanide is highly valued for the production or <a href="/facts/Acrylonitrile/zvhfg050">acrylonitrile</a> and <a href="/facts/Adiponitrile/h3RFognU">adiponitrile</a>, as well as alkali metal salts such as <a href="/facts/Potassium_cyanide/xcoXn4I8">potassium cyanide</a>. </p>
