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° to 600°C and a pressure in the range 5 to 20 psig.

Procédé pour la production de cyanure d'hydrogène, consistant à combiner l'ammoxydation du méthanol avec la décomposition du formamide dans le même réacteur, en présence d'un catalyseur à base d'oxyde de métal. Ce procédé consiste généralement à former un mélange réactionnel gazeux, constitué de méthanol, de formamide, d'ammoniac, d'oxygène et, facultativement, de formaldéhyde. On fait ensuite passer le mélange réactionnel sur un catalyseur d'oxyde de métal à une température de 200-600 degrés C et à une pression de 5-10 lb par pouce carré.
