Abstract:

An improved process is provided for selectively synthesizing pyridine and 3-alkylpyridine in high yield by reacting ammonia and a carbonyl reactant selected from the group consisting of formaldehyde, an aldehyde containing from 2 to 4 carbon atoms, a ketone containing from 3 to 5 carbon atoms, and mixtures thereof under effective conditions in the presence of a catalyst comprising an active form of a synthetic porous crystalline MCM-49 or synthetic porous crystalline material characterized by an X-ray diffraction pattern including interplanar d-spacings at 12. 36. +-. 4, 11. 03. +-. 2, 8. 83. +-. 14, 6. 18. +-. 12, 6. 00. +-. 10, 4. 06. +-. 07, 3. 91. +-. 07, and 3. 42. +-. 06 Angstroms, e. g. , MCM-22, and recovering from the resulting reaction mixture a product enriched in pyridine and 3-alkylpyridine.
