Abstract
A method is provided for synthesizing pyridine or alkylpyridines by reacting ammonia and a carbonyl reactant which is an aldehyde containing 2 to 4 carbon atoms, a ketone containing 3 to 5 carbon atoms or mixtures of said aldehydes and/or ketones under effective conditions in the presence of a catalyst comprising a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least about 12 and a constraint index within the approximate range of 1 to 12 and recovering from the resulting reaction mixture, a product containing at least one compound of pyridine or an alkylpyridine. Addition of methanol and/or formaldehyde to the feed improves selectivity to unsubstituted pyridine.
