摘要：
Catalytic properties of V2O5-WO3 preparations obtained from an oxalic acid solution og ammonium metavanadate and ammonium polytungstate were studied in an integral flow reactor. Activity of the catalysts expressed as a velocity constant per m(2) extrapolated to 623 K decrease with the increasing tungsta content. Selectivity at 50% conversion of benzene was of the order of 25% for V-O and V-W-O catalysts and decrease to 7% for W-O catalyst.
