Cyclohexanol CAS#108-93-0
High Flash Point and Boiling Range：Cyclohexanol has a relatively high flash point and boiling point, ensuring safer handling and thermal stability.
Effective Solvent：It can dissolve cellulose ethers, ester gum, shellac, low-viscosity silicones, and polyvinyl chloride, making it versatile in formulations.
Miscible with Oils and Hydrocarbon Solvents：Its miscibility with oils and hydrocarbon solvents allows compatibility with a wide range of industrial applications.
Distinctive Camphor-Like Odor：The characteristic odor makes it easily identifiable, which can be useful in quality control and handling.
Cyclohexanol CAS#108-93-0
Cyclohexanol is a clear, colorless to light yellow, viscous, and hygroscopic liquid with a camphor-like odor. Its odor detection threshold is reported to be 64 µg/m³ (155 ppbv). It features a relatively high flash point and boiling range, making it thermally stable. Cyclohexanol is an effective solvent for cellulose ethers, ester gum, shellac, low-viscosity silicones, and polyvinyl chloride. It has limited use in screen inks and is fully miscible with oils and hydrocarbon solvents.

Product Usage of Cyclohexanol CAS#108-93-0
Chemical Raw Materials
Nylon Production: Cyclohexanol is a key raw material for producing adipic acid and hexamethylenediamine. These intermediates are used to synthesize Nylon 66 via polycondensation. Nylon 66 exhibits excellent properties such as high strength, wear resistance, and chemical corrosion resistance, making it widely used in textiles, automobiles, electronics, machinery, and other industries.
Cyclohexanone Production: Cyclohexanol can be converted into cyclohexanone through catalytic dehydrogenation. Cyclohexanone is an important organic solvent and chemical intermediate, commonly used to produce caprolactam, adipic acid, rubber antioxidants, plasticizers, coatings, inks, and other products.
Medical Field
Cyclohexanol can serve as a solvent and intermediate in pharmaceutical synthesis. It is used as a reaction solvent in the synthesis of certain drugs and participates in the production of biologically active compounds, such as the synthesis of ceftriaxone capsules.
Surfactant Production
It can be used to synthesize surfactants, such as alkyl cyclohexanol polyoxyethylene ethers, which offer excellent emulsifying, dispersing, and wetting properties. These surfactants are widely applied in detergents, cosmetics, pesticides, and other industries.
Analysis and Detection
In analytical chemistry, cyclohexanol serves as a solvent for the colorimetric determination of molybdenum and rhenium, for the determination of aluminum with phenylhydrazine, and for the determination of bismuth using 8-carbonylquinoline or iodide.
