Abstract

The invention relates to a method for synergistic catalytic oxidation of cycloalkane by a metalloporphyrin MOFs PCN-222 (Co) / Cu (II) salt. The method comprises the following steps of: dispersing PCN-222 (Co) (1%-10%, g / mol) and a Cu (II) salt (0.01%-10%, mol / mol) into cycloalkane, sealing a reaction system, performing heating to 90-150DEG C while stirring, introducing an oxidant (0.10-2.0MPa), keeping the set temperature and pressure, carrying out stirring reaction for 2.0-24.0h to obtain a reaction solution, and conducting post-treatment to obtain the products cycloalkyl alcohol and cycloalkyl ketone. The method has the advantages of high cycloalkyl alcohol and cycloalkyl ketone selectivity, low reaction temperature, few byproducts, small environmental influence and the like. In addition,the cycloalkyl hydroperoxide content is low, and the safety coefficient is high. The invention provides an efficient, feasible and safe method for synthesizing cycloalkyl alcohol and cycloalkyl ketone through selective catalytic oxidation of cycloalkane.

Description

technical field

[0001] The invention relates to a method for synergistically catalyzing the oxidation of naphthenes to synthesize cycloalkanol and cycloalkanone by metalloporphyrin MOFs PCN-222(Co) / Cu(II) salt, 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, carried out at 150°C to 170°C, the main problems are high reaction temperat...
