Cyclohexanone,CAS 108-94-1

Cyclohexanone, also known as C6H10O, is a colorless to pale yellow liquid with distinctive properties, characterized by a minty or acetone-like odor that becomes slightly rubbery in pure form. In chemical structure, cyclohexanone is a cyclic ketone compound formed by replacing one carbon atom in a cyclohexane molecule with an oxygen group. This molecular structure gives it unique physical and chemical properties. The physical properties of cyclohexanone make it excel in various applications. Its density is less than water, with a low flash point (111°F), meaning it can evaporate at relatively lower temperatures. Its vapor density is greater than air, making it an effective medium in certain chemical reactions. Additionally, cyclohexanone is a highly volatile liquid that can be mixed with most organic solvents but has low solubility in water, which makes it widely applicable in the solvent industry. In industrial production, cyclohexanone is produced in billions of kilograms per year, mainly used as a precursor for nylon production. Nylon is a widely used synthetic polymer found in clothing, carpets, and engineering plastics, among other products. Additionally, cyclohexanone is often used as a medium for chemical reactions, participating in various organic synthesis reactions to produce various chemicals. Meanwhile, due to its good solubility, it is also used as a solvent for paint, coatings, and cleaning agents. Cyclohexanone has many uses, but it should be noted that it has certain biological activity towards the body and may exist as an exogenous metabolite in the body. Therefore, appropriate protective measures should be followed when handling and using cyclohexanone, avoiding inhalation, contact with skin and eyes, and improper emissions to protect the environment and workers' health. Cyclohexanone is a versatile organic compound with wide applications in the chemical industry, from nylon production to solvent applications, and is present everywhere. However, it should be used with caution to ensure safety and environmental protection. The CAS number of cyclohexanone is 108-94-1, and it has many other names, such as anonon, hexanone, and cetone, reflecting its applications and recognition in different fields.
