Cyclohexanone, also known as cyclohexanone and cyclohexanone in carbon disulfide, has a chemical formula of C₆H₁₀O, a CAS number of 108-94-1, and a molecular weight of 98.14 , appears as a colorless or light yellow transparent liquid with a strong irritating odor. The melting point is -45°C and the boiling point is 155.6°C. It is slightly soluble in water and miscible in most organic solvents such as alcohol, ether, benzene, and acetone. . In addition, cyclohexanone is flammable, has anesthetic and irritating effects, and is a hazardous chemical.

Cyclohexanone is a widely used organic compound that can undergo various reactions such as oxidation and polymerization under the action of a catalyst, and is used as an intermediate for a variety of chemical products. For example, in the field of chemical fiber, cyclohexanone is an important raw material for the synthesis of nylon, caprolactam, and adipic acid; in the field of coatings, cyclohexanone can be used to produce polyurethane paint, epoxy resin paint, and various vinyl resin paints; in the pharmaceutical field , Cyclohexanone can be used in the production of drug gabapentin intermediates, progesterone, anti-epileptic drugs, etc. In addition, cyclohexanone is also an important organic solvent. Cyclohexanone has good solubility and low volatility and can be used as an ideal solvent for a variety of dyes, pesticides, paints, rubber, cosmetics, polymers, etc.

The production process of cyclohexanone is divided into two types. The traditional cyclohexanone production process includes phenol hydrogenation method, benzene hydrooxidation method, cyclohexane liquid phase oxidation method, etc.; the new production process includes cyclohexene hydration method, molecular sieve method, etc. Catalytic oxidation method, metal catalytic oxidation method, bionic catalytic oxidation method, etc. Among them, the phenol hydrogenation method is the earliest process to realize the industrial production of cyclohexanone. The cyclohexanone it produces is of good quality and highly safe, but it requires the use of a relatively expensive raw material – phenol. The production cost is high, and its application is limited. Limitations; The cyclohexane oxidation method for preparing cyclohexanone has low equipment requirements and high raw material utilization efficiency. Therefore, it is currently the most widely used industrial production process, accounting for more than 90%.

At present, there are about 30 cyclohexanone manufacturers, including Dafeng Haili, Shandong Haili, Luxi Chemical, Fujian Shenyuan, Hengyi Petrochemical, etc. Most cyclohexanone companies mainly provide raw materials for their internal production of caprolactam or adipic acid and other products. According to the “2020-2024 Environmental Protection Agency” released by the Industrial Research Center Risk investment situation and investment and financing strategy guidance report on hexanone industry

It shows that in 2021, my country’s cyclohexanone production was 4.013 million tons, and the consumption of cyclohexanone consumed in caprolactam production accounted for 60.1%.
Industrial analysts said that the price of raw materials such as pure benzene has been declining recently, which may lead to a reduction in cyclohexanone production costs and product prices. keep falling. As the new production capacity of domestic cyclohexanone companies is completed and put into operation, domestic cyclohexanone production capacity will also increase. However, its main downstream application areas, caprolactam and adipic acid production companies, have no plans to expand production and put into production in the short term, and the solvent field The demand for cyclohexanone is low. Therefore, the market supply and demand of cyclohexanone industry may be unbalanced in the future, which is not conducive to the growth of corporate operating profits.
