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.degree. to 60.degree. C. and in the second step at a temperature about 10.degree. to 30.degree. C. lower than in the first step.
