Synthesis of Pyridines Over Zeolites in Gas Phase
View through CrossRef
Pyridine and its methyl derivatives were synthesized in vapor phase from ethanol, formaldehyde and ammonia over zeolites H-ZSM-5, Beta, mordenite and over SiO2. Both the Si/Al molar ratio and modification of zeolite with zinc strongly influenced the selectivity in pyridine and alkylpyridines formation. The highest yield of pyridine was obtained over ZSM-5 modified with zinc and the highest pyridine-to-alkylpyridines ratio was achieved over H-ZSM-5 with high Si content (Si/Al ratio 140). The conversion of ethanol and the selectivity in pyridine formation were correlated with the acidity of used catalyst.
