FIELD: chemical industry. SUBSTANCE: catalyst comprises vanadium, alkali metal or sulfur oxides applied onto silicic support. Support of commercial catalyst or carcass which is essentially commercial catalyst after removing acid-soluble active component therefrom contains pores with radii from . Amount of pores with radii from
is 5-70 % and with radius of more than
not higher than 50%. Volume of catalyst carcass from
is 0.30-0.98 cubic cm/cubic cm. Silicic support is natural or synthetic silica or combination thereof. EFFECT: more efficient convention catalyst. 4 cl, 7 ex, 1 tbl
