Tungsten ionic liquids: Application of cyclohexanol oxidation

The ionic liquid [(CH3)N(n-C8H17)3]2W2O11 can be applied as a catalyst in cyclohexanol oxidation.Experiments show that it has good catalytic activity on cyclohexanol oxidation with H2O2 as the oxidant.It was conducted at 65 ℃ by adding substrate(5 mmol),catalyst(50 μmol) and H2O2(15 mmol) in a stirred mixture in a reactor.The yield is more than 99 %.The catalyst could be recycled after simple filtering.
