Реферат:
Development of catalysts based on modified zeolites with a microporous or micro/mesoporous structure and on microporous metallosilicates is aimed at creating high-selectivity method of obtaining pyridine and alkylpyridines. In this study, pyridine and methylpyridines have been synthesized for the first time via the heterogeneous catalytic reaction of ethanol with formaldehyde and ammonia catalyzed by the microporous zeolites Y, Beta, ZSM-12, and ZSM-5 in the H-form and by a granular zeolite Y with a combined, micro-meso-macroporous structure (HY-MMM). The latter zeolite is particularly effective in the synthesis of picolines, affording a picoline selectivity of 46–63% at an ethanol conversion of 70–80%. Among the microporous catalysts, the most active ones are the highly decationized zeolites H-Y and H-Beta. The major products of the reaction occurring over H-Beta and H-ZSM-5 are pyridine (up to 50%) and picolines (up to 40%), and the main products of the same reaction carried out over H-Y and H-ZSM-12 are picolines (45–52%) and lutidines (19–25%). For zeolite H-Y-MMM, the ethanol conversion and the composition of pyridines depend on the reaction conditions.
