| Abstract: | The reaction of n-butanol, formaldehyde and ammonia has been carried out over modified ZSM-S catalysts, to get 3,S diethylpyridine selectively. Among all the catalysts ZrZSM-5 has shown high activity with 73.4 wt% of 3,5-diethylpyridine at 97.0 wt% conversion of n- butanol. The effects of temperature, WHSV and molar ratio have been studied in the synthesis of 3,S-diethylpyridine over ZrZSM-S. The other major products are lutidines and collidines. Our studies have shown that modified ZSM-S catalysts can be used for the synthesis of pyridine and substituted pyridines from various alcohols or aldehydes via dehydrocyclization and dehydrogenation. |
