Summary

In situFTIR spectroscopy was used to study the interaction of<span style='font-family:Symbol;mso-bidi-font-family:Symbol'>b-picoline with the surface of a V-Ti-O catalyst in the temperature range of 120-300°C.b-picoline was found to react with the Lewis acid sites of the catalyst to form a nitrogen-coordinated complex. This complex turns into an aldehyde-like complex at</o:p>150-250°C and then into a nicotinate, which is a direct precursor of nicotinic acid.</o:p>
