Selective oxidation of isobutane over Mo-V-Te mixed oxide catalysts with different tellurium contents
A series of MoV0.3Tex (x = 0-0.3) mixed oxides were prepared and investigated for the selective oxidation of isobutane. Among them, MoV0.3Te0.23 showed the best methacrolein and methacrylic acid selectivity (as high as 17% and 16%, respectively), and the yield to methacrolein and methacrylic acid reached 3.6% and 3.5%, respectively, at 21.3% isobutane conversion at 440 degrees C.
