    摘要： The present invention relates to a single step new catalytic process for the production of pyridine and picolines from a mixture of carbonyl compound and ammonia in the presence of zeolite catalyst with MFI topology containing Si and Zr and/or Sn as zeolite constituents in gas phase. The catalyst is preferably loaded with other metal ions such as lead, nickel, thallium or their mixture for increased yield. Present invention provides the novel use of above mentioned zeolite catalysts for the production of picolines for the first time, with improved yield of desired products picolines.

    摘要： There is provided a high efficiency base synthesis process for shape selective production of pyridine and picoline products from ammonia and C.sub.1-5 carbonyl compounds. The process includes reacting ammonia and at least one C.sub.1-5 carbonyl reactant under suitable reaction conditions of temperature, pressure, and space velocity in the presence of a catalyst comprising a molecular sieve to produce a primary product comprising pyridine or picoline products and polyalkylpyridines or other higher molecular weight aromatic species, separating and collecting the pyridine or picoline products from the polyalkylpyridines or other higher molecular weight aromatic species, and circulating the polyalkylpyridines or other higher molecular weight aromatic species to the same or another catalyst under conversion conditions to yield additional pyridine or picoline products with substantially reduced amounts of polyalkylpyridines or other higher molecular weight aromatic species.
