Zusammenfassung:Prodn. of niacin (I) from alkylpyridines (II) having beta-methyl or -ethyl substits. comprises vapour-phase oxidation with air and steam over a solid V2O5 catalyst contg. TiO2 as a promoter which has been sintered at 1250 degrees C. Pref. the V : Ti ratio is 100/25 in atom %, and the catalyst may additionally contain alkali oxides as additional promoters.
