The invention relates to Co (II) and Ni (II) doped montmorillonite, a preparation method thereof and application thereof in synthesizing cycloalkanol and cycloalkanone by catalytic oxidation of cycloalkane, belonging to the field of industrial catalysis and fine organic synthesis. The method comprises the following steps: dispersing montmorillonite in mixed aqueous solution of Co (II) salt and Ni (II) salt (total amount is 30.0mmol), stirring and loading metal ions, collecting solid, performing high temperature treatment, and performing post-treatment to obtain Co (II) and Ni (II) doped montmorillonite. The obtained Co (II) and Ni (II) doped montmorillonite is applied to catalyzing cyclane to obtain products of cycloalkyl alcohol and cycloalkyl ketone. The catalytic reaction has the advantages of high selectivity of the naphthenic base alcohol and the naphthenic base ketone, low reaction temperature, few byproducts, small environmental influence and the like. In addition, the content of the naphthenic hydroperoxide is low, and the safety coefficient is high. The invention provides a high-efficiency, feasible and safe method for synthesizing naphthenic alcohol and naphthenic ketone by selective catalytic oxidation of naphthenic hydrocarbon. |
