Vanadium phosphorus oxide composite as an efficient catalyst for hydrocarbon oxidations using tert-Butyl hydroperoxide

Calcined vanadium phosphorus oxide (VPO) prepared by an organic method isfound to be an activeAnd effective catalyst for the oxidation of various alkanes such ascyclohexane, n-hexane and cycloheptane in acetonitrile solvent using the environmentallybenign oxidant, tert-Butyl hydroperoxide, where the oxidation mechanism is believed toinvolve a reversible V4+/V5+ redox cycle. This heterogeneous catalyst at the end of thereaction is easily separated by the least cost of the product. This reaction is investigated ina polar and nonpolar solvent with different dielectric constant. Cobalt metal is also usedas a catalyst enhancer and TBHP as an oxidizing agent. After catalytic tests anddetermining the best catalyst and ideal amount of cobalt percent improvement, detectionand analysis will be done by analyzing XRD, SEM, TGA, IR
