Abstract
The present invention provides a novel Fe-Pd catalyst prepared by impregnating, either together or respectively, an iron source compound and a palladium source compound onto a carrier selected from the group consisting of silica, alumina and silica-alumina, and drying and calcining said Fe-Pd impregnated carrier in a flow of air or H.sub.2 /N.sub.2 ; and a method for preparing a mixture of cyclohexanol and cyclohexanone by selectively oxidizing cyclohexane in a reaction medium provided with hydrogen and oxygen gases in the presence of said Fe-Pd catalyst.
Claims10
A method for preparing a mixture of cyclohexanol and cyclohexanone by selectively oxidizing cyclohexane at a temperature ranging from 10.degree. to 50.degree. C. in a reaction medium bubbled with hydrogen and oxygen gases in the presence of an iron-palladium catalyst prepared by impregnating, either together or separately, an iron salt compound and a palladium salt compound onto a carrier, followed by drying said impregnated carrier and calcining said dried carrier in a flow of air or a mixture of hydrogen and nitrogen gases, wherein the weight ratio of said cyclohexane to said catalyst is in the range of 3 to 10 and the weight ratio of said reaction medium to said catalyst is in the range of 10 to 40.
