There is sizeable interest in the study of vanadium–titanium oxide catalysts for selective oxidation of organic compounds. This chapter discusses the vanadium–titania catalysts to be also effective for the oxidation of 13-picoline to nicotinic acid. The chapter describes the study on the influence of the chemical composition of the vanadium–titania system on the phase composition, the structural arrangement, and catalytic behavior in β-picoline oxidation. In this purpose, binary samples, containing 5 to 75 wt % of V2O5 and 95 to 25 wt % of TiO2, were prepared by mixing titania of the anatase modification produced according to the sulfate technology, with vanadyl oxalate solution, drying the mixture, and calcining it at 450°C. Individual oxides were prepared from the corresponding raw materials in the same manner. Thermal argon adsorption was used to determine the specific surface area of the samples. X-ray diffraction (XRD) analysis of the catalysts was carried out, using a URD-6 diffractometer with monochromatic CuKα radiation. IR spectra were recorded at 200 to 1300 cm−1, using a BOMEM Fourier-spectrometer. Weighed 2 mg catalyst to be studied were pelleted by pressing with CsJ. Transmission electron microscopy (TEM) studies were carried out, using a JEM-4000FX microscope with resolution of 1.1 Å, and accelerating potential of 400 kV. Catalytic activity of the 0.25–0.50 mm fraction of catalysts was measured, using a flow circuit setup, with a differential reactor at 250–300°C. The inlet reaction mixture was 1 vol % of 13-picoline, 20 vol % of oxygen, 30 vol % of water steam, and the balance nitrogen; contact time was 0.15–3.00 s. The reaction products were analyzed chromatographically. Chemical composition, specific surface area, and phase composition of the examined catalysts are discussed in the chapter. From the physicochemical data, it is found the catalysts differ in XRD phase composition, microstructure, and molecular structure depending on the concentration of vanadium oxide.
