ABSTRACT:
A process for the production of hydrogen cyanide which comprises combining methanol ammoxidation with formamide decomposition in the same reactor, using a metal oxide catalyst. This process generally involves forming a gaseous reaction mixture comprising methanol, formamide, ammonia, oxygen and optionally formaldehyde. This reaction mixture is then passed over the metal oxide catalyst at a temperature in the range 200.degree. to 600.degree. and a pressure in the range 5 to 20 psig.
