- 1 - Abstract of the Disclosure Pyridine is prepared by ammoxidation (= reaction with oxygen or an oxygen-containing gas and ammonia, if appropriate in the presence of steam) of cyclopenta- diene in the presence of a tellurium-free silica gel ca- talyst, ?-A12O3 catalyst and/or aluminum silicate catalyst, which is preferably also doped with transition metal oxides and/or the oxides of gallium and/or indium and, if appropriate, also contains trivial quantities of further customary additives. The surface area of the catalyst should be between about 75 and 800 m2/g and the pore volume between about 0.2 and 2 cm3/g, and the reaction temperature should be between about 200 and 400°C. The pyridine formed in the process is free from picolines and higher homologs.
