Claims
- 1. A process for preparing cyclohexanol and cyclohexanone by oxidizing cyclohexane with an Fe/Pd catalyst in a flow of hydrogen and oxygen gases, and in the presence of a mixture of acetone and acetic acid wherein the ratio of acetone to acetic acid ranges from 1:0.05 to 1:1.5 by weight.
- 2. The process of claim 1, wherein the mixture of acetone and acetic acid is in an amount of 4 to 50 times by weight of the Fe/Pd catalyst.
- 3. The process of claim 1, wherein cyclohexane is in an amount of 1 to 20 times by weight of the Fe/Pd catalyst.
- 4. The process of claim 1, wherein the Fe/Pd catalyst is a mixture of a palladium compound supported by a carrier and an iron based compound.
- 5. The process of claim 4, wherein the iron based compound is selected from the group consisting of FeCl.sub.2, FeCl.sub.3, FeO, Fe.sub.2 O.sub.3, FeSO.sub.4, Fe.sub.2 (SO.sub.4).sub.3, and Fe(OAc).sub.2.
- 6. The process of claim 4, wherein the carrier is selected from the group consisting of alumina, silica, silica-alumina, and carbon.
- 7. The process of claim 1, wherein the Fe/Pd catalyst is prepared by impregnating a palladium compound onto an iron oxide, followed by drying the impregnated iron oxide, and then calcining the dried oxide under air or hydrogen.
- 8. The process of claim 7, wherein the iron oxide is FeO, Fe.sub.3 O.sub.4, or Fe.sub.2 O.sub.3.
- 9. The process of claim 7, wherein the palladium compound is PdCl.sub.2 or [Pd(NO.sub.3).sub.2 ].
- 10. The process of claim 7, wherein the catalyst is activated.
