ABSTRACT:
Pyridine is prepared by ammoxidation (=reaction with oxygen or an oxygen-containing gas and ammonia, if appropriate in the presence of steam) of cyclopentadiene in the presence of a tellurium-free silica gel catalyst, .gamma.-Al.sub.2 O.sub.3 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 m.sup.2 /g and the pore volume between about 0.2 and 2 cm.sup.3 /g, and the reaction temperature should be between about 200.degree. and 400.degree. C.
The pyridine formed in the process is free from picolines and higher homologs.
