Abstract
The reaction of propionaldehyde, formaldehyde and ammonia was carried out over modified H-ZSM-5 catalysts. Typically over H-ZSM-5 (Si/Al=150), at 400°C, the yield of 3,5-lutidine was 63.1 wt.-% at 66.2% conversion of propionaldehyde. The cation effect was observed in the increase of collidines in the product. Our studies have established that useful substituted pyridines can be synthesized from C1-C4 aldehydes and alcohols in the presence of ammonia via dehydrocyclization and dehydrogenation.
