    摘要： An improved method of catalytic gaseous chemical synthesis of pyridine by reaction of ammonia and a carbonyl compound, preferably with added hydrogen, is described herein. The process employs as the catalyst a crystalline aluminosilicate zeolite which has been ion exchanged with a Group VIII metal of the Periodic Table. The preferred metal is palladium. Suitably, the Group VIII metal is present in an amount of about 0.01% to 5% by weight of the catalyst, preferably 0.1% to 2%. The crystalline aluminosilicate zeolite catalyst suitably has a silica to alumina mole rate of at least 15, preferably 30 to 200, and optimally, about 120 to 150. The process of the invention provides a high and selective yield of pyridine over a prolonged reaction period, and affords facile restorability of the catalyst.

    摘要： Formaldehyde, acetaldehyde and ammonia are reacted in the vapor phase over a catalyst in the substantial absence of molecular oxygen and in the presence of at least three moles of steam for each mole of total aldehyde reactants. The useful life of the catalyst in the production of pyridine and/or methyl pyridines by this reaction is thereby increased and the coking of the catalyst is reduced.
