Method for preparing cyclopentanol and cyclopentanone by using cyclopentane

The invention discloses a method for preparing cyclopentanol and cyclopentanone by using cyclopentane, and belongs to the technical field of preparation of fine chemicals. According to the method, cyclopentane is taken as a reactant, oxygen is taken as an oxidant, and a supported gold catalyst is used for catalytic oxidation of cyclopentane so as to synthesize cyclopentanol and cyclopentanone. A reaction is performed for 3 hours at a reaction temperature of 150 DEG C and at an oxygen pressure of 2.0MPa, the conversion rate of cyclopentane is as high as 10.2%, and cyclopentanol and cyclopentanone are respectively 32.6% and 45.4% in selectivity. According to the process for preparing cyclopentanol and cyclopentanone, the cyclopentane raw material is cheap and easy to obtain; the oxygen is taken as the oxidant; the reaction condition is mild; the used catalyst is easy to separate and recycle; no organic solvents or additives are needed, so the process is an environment-friendly technique.
