    摘要: Pyridine is prepared by reacting acetaldehyde, ammonia and oxygen at elevated temperatures and in the presence of a condensation catalyst, the oxygen (or air) oxidatively demethylating, in situ, the picolines and/or higher condensation products produced along with pyridine. A second embodiment includes incorporating methanol in the above reaction mixture. A third embodiment includes incorporating isobutyraldehyde in the above reaction mixture. These processes obviate the need for formaldehyde as a reactant.
