ABSTRACT:
Process for the production of 2,4,6-trimethyl pyridine wherein a carbonyl compound such as acetone is reacted with ammonia in the presence of a condensation catalyst at a temperature in the range from 100.degree. to 200.degree. C. to produce a mixture of products containing 2,2,4,6-tetramethyl-1,2-dihydropyridine which is then purified. The substantially pure dihydropyridine is then contacted with a cracking catalyst at a temperature in the range from 250.degree. to 450.degree. C. to produce 2,4,6-trimethyl pyridine in high yield.
