Abstract

The invention relates to a method for catalytic oxidation of cycloalkane by bimetallic porphyrin MOFs PCN224 (Co@Zn), which comprises the following steps: dispersing bimetallic porphyrin MOFs PCN224 (Co@Zn) in cycloalkane, wherein the mass of the bimetallic porphyrin MOFs PCN224 (Co@Zn) in cycloalkane is 1-10% of the molar mass of the cycloalkane, g / mol; and sealing the reaction system, heating to90-150 DEG C while stirring, introducing an oxidant, keeping the set temperature and pressure, stirring to react for 2.0-24.0 hours, and carrying out after-treatment on the reaction solution to obtain the products naphthenic alcohol and naphthenic ketone. The method disclosed by the invention has the advantages of high naphthenic alcohol and naphthenic ketone selectivity, low reaction temperature, few byproducts, small environmental influence and the like. In addition, the content of cycloalkyl hydroperoxide is low, and the safety coefficient is high. The invention provides an efficient, feasible and safe method for synthesizing naphthenic alcohol and naphthenic ketone through selective catalytic oxidation of cycloalkane.

Description

technical field

[0001] The invention relates to a method for synthesizing cycloalkanol and cycloalkanone by catalytically oxidizing cycloalkane with double metal porphyrin MOFs PCN-224 (Co&Zn), which belongs to the field of industrial catalysis and fine organic synthesis. Background technique

[0002] Catalytic oxidation of naphthenes is a very important conversion process in the chemical industry. The oxidation products cycloalkanol and cycloalkanone are not only important organic solvents, but also important fine chemical intermediates, widely used in pesticides, medicines, dyes, surface Synthesis of fine chemical products such as active agents and resins, especially the production of polyamide fibers nylon-6 and nylon-66. At present, the industrial catalytic oxidation of naphthenes is mainly based on homogeneous Co 2+ or Mn 2+ As a catalyst, oxygen (O 2 ) is an oxidizing agent, which is carried out at 150°C to 170°C. The main problems are that the reaction temperature ...
