Open the CIPO recordAbstract From the Canadian patent
Catalysts useful for the oxidation and ammoxidation of alcohols containing the elements iron and molybdenum in a catalytically active oxidized state exhibit improved selectivity and yield upon being activated by contacting calcined catalyst particles sequentially with a molecular oxygen-free reducing gas and an oxygen-containing gas at catalyst activating conditions. These activated catalysts are especially useful for the production of hydrogen cyanide from methanol ammonia, and an oxygen-containing gas.
