Such pyridine bases as pyridine, picoline, lutidine, collidine, etc. can be produced in the present invention. For example, when formaldehyde and acetaldehyde are used together with ammonia, pyridine and 3-picoline are obtained. When formaldehyde and propionaldehyde are used together with ammonia, 3,5-lutidine and a small amount of 3-picoline are obtained. When formaldehyde, acetaldehyde and propionaldehyde are used together with ammonia, pyridine, 3-picoline and 3,5-lutidine are obtained. Further, when formaldehyde and acetone are used together with ammonia, 2,6-lutidine is principally obtained. When diethylketone or methylethylketone is used together with ammonia, 2,6-diethyl-3-methylpyridine or 2,3,6-trimethylpyridine is obtained.
