...By improving and devising catalysts and reaction procedures, the selectivity of acrylonitrile production has gradually improved, and currently, only 0.025 kg of acetonitrile and 0.05 kg of hydrogen cyanide are produced as by-products per 1 kg of acrylonitrile. The synthesis of hydrogen cyanide by ammoxidation of methane is also called the Andrussow process. Platinum or a platinum-rhodium alloy is used as a catalyst, and the reaction is carried out at high temperatures of 800 to 1000 °C. ... *Some of the terminology that refers to the "Andrussow process" is listed below.
