Cyclohexanol (C₆H₁₁OH, CAS 108-93-0) is a colorless, camphor-odored secondary alcohol that sits at the heart of the nylon supply chain: together with cyclohexanone it forms “KA oil”, the industrial feedstock for adipic acid (nylon-66) and caprolactam (nylon-6). Beyond nylon, its balanced solvent power and its clean esterification chemistry make it a versatile industrial workhorse — a solvent for coatings, varnishes, inks and paint strippers, the alcohol partner of dicyclohexyl phthalate (DCHP) plasticizers, a textile leveling agent, and a building block for fine-chemical synthesis.
One alcohol, four core value propositions:
Nylon-Industry Intermediate (Core Application):
● the alcohol component of KA oil — the route to adipic acid and caprolactam for nylon-66 and nylon-6;
Industrial Solvent:
● dissolves resins, waxes, varnishes and inks for coatings, paint strippers and printing applications;
Plasticizer Ester Chemistry:
● esterified with phthalic anhydride to dicyclohexyl phthalate (DCHP) plasticizer;
Textile & Fine-Chemical Auxiliary:
● leveling agent in dyeing, plus a building block for agrochemical and fragrance synthesis.

Cyclohexanol (MW 100.16) is the monohydroxy derivative of cyclohexane: a saturated six-membered ring bearing one secondary –OH group. It is a weak, neutral secondary alcohol with the typical reaction profile — esterification with acids/anhydrides (e.g. phthalic anhydride → DCHP), oxidation to cyclohexanone, and dehydration to cyclohexene. Its melting point of ≈ 23 °C lies very close to room temperature: the product is a low-viscosity liquid in warm weather but crystallizes readily in cool storage — a practical consideration for pumping, dosing and winter logistics. It is only slightly soluble in water (≈ 3.6 g/100 mL at 20 °C) but miscible with most organic solvents, which underlies its role as an industrial solvent and reaction medium.
● Nylon-chain feedstock: the alcohol half of KA oil — a direct route into adipic acid and caprolactam chemistry.
● Balanced solvent power: dissolves resins, waxes, varnishes and inks across coating and ink systems.
● Clean esterification: reliable partner for phthalate and other ester plasticizer synthesis (DCHP).
● Versatile secondary alcohol: oxidation, esterification and dehydration all proceed predictably.
● Textile auxiliary value: effective leveling and penetration behavior in dyeing processes.
● Broad downstream reach: nylon, coatings, plastics, textiles and fine chemicals from one molecule.
● Consistent quality: controlled assay, water content and purity with COA.
Cyclohexanol is the alcohol component of KA oil (cyclohexanone/cyclohexanol mixture), the industrial gateway to the nylon chain:
● Adipic acid route: KA oil oxidation (with nitric acid) produces adipic acid — the nylon-66 monomer;
● Caprolactam route: cyclohexanone (from cyclohexanol) is converted via cyclohexanone oxime to ε-caprolactam — the nylon-6 monomer;
● KA oil production: cyclohexanol is oxidized to cyclohexanone or co-produced in the KA-oil mixture;
● Engineering plastics and fibers: nylon-6 and nylon-66 for fibers, engineering plastics and films.
● Coatings and varnishes: dissolves alkyd, epoxy and nitrocellulose resin systems;
● Paint strippers: effective component in solvent-based stripping formulations;
● Printing inks and thinners: resin and dye solvency for inks and diluents;
● Wax and polish formulations: solvency for natural and synthetic waxes.
● Dicyclohexyl phthalate (DCHP): esterified with phthalic anhydride — a low-volatility plasticizer for PVC;
● Ester plasticizer range: cyclohexyl esters for flexible PVC and coatings;
● Polymer auxiliaries: solvent and intermediate roles in resin compounding;
● Adhesive and sealant formulations: solvency and plasticizing contribution.
● Leveling agent: evens dye uptake in batch dyeing processes;
● Dyeing auxiliaries: penetration and dispersion support in dye baths;
● Fiber processing: solvent and carrier roles in finishing auxiliaries;
● Consistent performance: controlled purity for reproducible textile results.
● Agrochemical intermediates: cyclohexyl derivatives for crop-protection chemistry;
● Fragrance chemistry: cyclohexyl esters and ethers used in aroma compositions;
● Laboratory reagent: high-purity grade for analytical and research use.

Cyclohexanol is the alcohol component of KA oil, the industrial feedstock for adipic acid (nylon-66) and caprolactam (nylon-6); it is also an industrial solvent for coatings, varnishes, inks and paint strippers, the alcohol partner of dicyclohexyl phthalate (DCHP) plasticizers, a textile leveling agent, and a building block for agrochemical and fragrance intermediates.
Cyclohexanol is oxidized to cyclohexanone (or co-produced with it as KA oil). KA oil is then oxidized with nitric acid to adipic acid — the nylon-66 monomer — while cyclohexanone is converted through cyclohexanone oxime to ε-caprolactam, the nylon-6 monomer. Because both major nylon families start from this one C₆ alcohol/ketone pool, cyclohexanol is one of the most important commodity intermediates in the fiber and engineering-plastic chain.
Cyclohexanol (C₆H₁₁OH) is the secondary alcohol; cyclohexanone (C₆H₁₀O) is its oxidation product, the ketone. They frequently appear together as KA oil (ketone-alcohol mixture). Cyclohexanol is the reduced form — a liquid above ≈ 23 °C with a camphor-like odor — while cyclohexanone is a higher-vapor-pressure ketone solvent and the direct precursor of caprolactam. Each has its own downstream value, and their ratio in KA oil is tuned by the oxidation process.
Cyclohexanol is harmful by inhalation and if swallowed (H302/H332) and irritating to the respiratory system and skin (H315/H335). It is a combustible liquid (flash point ≈ 68 °C): keep it away from ignition sources, strong oxidizers and acids, use adequate ventilation, and handle with gloves and eye protection. Note that it crystallizes below ≈ 23 °C — maintain temperature during cold-weather handling.
