Hydrogen cyanide is an important building block chemical for the synthesis of a variety of industrial important chemicals, such as adiponitrile, nitrilotriacetic acid, lactic acid, methylmethacrylate, and 2-hydroxy-4-methylthiobutyric acid. The primary commercial routes to hydrogen cyanide are the reaction of methane and ammonia under aerobic (Andrussow Process) or anaerobic conditions (Degussa Process), or the separation of hydrogen cyanide as a by-product of the ammoxidation of propylene. The ammoxidation of methanol represents an attractive alternative route to HCN for a number of reasons. First, on a molar basis, the price of methanol has become close to that of methane as world methanol capacity has increased. Second, shipment of methanol and ammonia for on-site production of HCN in areas where cheap natural gas is not available could offer a cost and safety advantage. The ammoxidation of methanol as a route to HCN was originally suggested by Andrussow, and Distillers has early patents on the use of silica supported molybdenum oxides and antimony tin oxides. More recently, Japanese companies have reported improved multicomponent systems. The studies of binary oxide systems containing molybdenum or phosphorous have led to the development of an iron molybdenum oxide catalyst and a manganese phosphorous oxide catalyst capable of ammoxidizing methanol in nearly 90% yields.
