Currently, 4-methylpyridine is produced by vapor-phase condensation of acetaldehyde and ammonia (3:1) with subsequent isolation of 4-methylpyridine from the reaction mixture. Reactants are exposed to dehydration-dehydrogenation catalysis such as lead oxide, copper oxide on alumina, thorium oxide, zinc oxide or cadmium oxide on silica-alumina, or cadmium fluoride on silica-magnesia at 400-500°C. This results in a 60% yield of 4-methylpyridine which is isolated by fractional distillation (USEPA 1982). Another production method involves the isolation from by-products of coking operations. The crude pyridine extracts come from noncondensable and condensable coke-oven gasses that have been dehydrated and separated by fractional distillation, but only 45% of 4-methylpyridine is obtained (USEPA 1982). 4-Methylpyridine also can be isolated from a dry distillation of bones or coal (Hawley 1977).
