Catalytic Properties Of Promoted Vanadium Oxide In The Oxidation Of Ethane In Acetic Acid

Abstract ReO 3 -like oxides belonging to various systems such as : [V-O], [V-P-O] and [Mo-V-Nb], have been prepared, characterized and studied in the mild oxidation catalysis of ethane, Pure and Pd doped (VO) 2 P 2 O 7 are found to be very selective catalysts for the direct oxidation of ethane in acetic acid and anhydride as low as 250°C, whereas oxides having the composition [Mo 0.73 V 0.18 Nb 0.09 ] catalyze selectively either the oxidative dehydrogenation of ethane in ethylene near 350°C, or its oxidation to acetic acid at lower temperatures, according to the mode of preparation.
