A. THE INVENTION CONCERNS CATALYSTS INTENDED FOR THE TRANSFORMATION OF 2-METHYLPYRAZINE INTO 2-CYANOPYRAZINE BY REACTION WITH AMMONIA GAS AND OXYGEN. B. THESE CATALYSTS ARE CONSTITUTED BY COMBINATIONS OF ANTIMONY AND VANADIUM ELEMENTS WITH OXYGEN AND AT LEAST ONE OF THE ELEMENTS IRON, COPPER, TITANIUM, COBALT, MANGANESE AND NICKEL AND FURTHER OF SILICATES WITH STRATIFIED NETWORK OR DIOXIDE WITH SILICONE SCATTERED. C. THESE CATALYSTS ARE VERY SELECTIVE AND GIVE REACTIONAL RETURNS PER UNIT OF HIGH VOLUME AND TIME. |
