Abstract: The gaseous mixture resulting from the catalytic reaction of 3-methylpyridine with ammonia and oxygen is treated with water to recover 3-cyanopyridine. The treatment takes place in two steps. In the first step there is used a temperature of about 30 DEG to 60 DEG C. and in the second step at a temperature about 10 DEG to 30 DEG C. lower than in the first step.

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.
