CATALYST AND METHOD OF PRODUCING NICOTINIC ACID Russian patent published in 2009 - IPC B01J23/22 C07D213/80 B01J21/06 B01J23/16 

FIELD: chemistry.

SUBSTANCE: invention relates to vanadium-titanium oxide catalysts, used for producing nicotinic acid through gas phase oxidation of β-picoline with oxygen and methods of producing nicotinic acid using said catalysts. The catalyst contains vanadium oxide, titanium oxide and modifying additives - cerium oxide or one or more metal oxides, chosen from groups IV and V of the periodic table of elements with total content of oxides of modifying elements in the range 1.0 to10.0 wt %, vanadium oxide in amount of 5.0 to 75.0 wt %, and titanium oxide - the rest. A method is described for producing nicotinic acid through oxidation of β-picoline with oxygen in one or more successive layers of catalyst with different grain-size in a tube reactor in the presence of the catalyst described above.

EFFECT: increased activity of catalyst and selectivity on nicotinic acid.
