Abstract
For the catalytic reaction of 2-methylpyrazine with ammonia and oxygen to form 2-cyanopyrazine there are used compounds of the elements antimony, vanadium, and oxygen and at least one of the elements iron, copper, titanium, cobalt, manganese, and nickel, whereby the atomic ratio of antimony to vanadium is greater than 1 and which contain besides these compounds a lattice layer silicate and a highly dispersed silica. These catalysts are very selective and result in high yields and high space-time-yields.
