Documented Uses

• Textiles (Fiber & Fabric Manufacturing) [Category: Industry]
• Painting (Solvents) [Category: Paint]
• Solvent for alkyd resins, alcohol-soluble phenolic resins, ethyl cellulose. Manufacture of celluloid; finishing textiles; in insecticides.
• Oxidation of cyclohexanol to adipic acid is the most important use... 90% of adipic acid produced in the United States is used in the manufacture of nylon-6,6... The next important usage of cyclohexanol, pure or admixed with cyclohexanone as KA-oil, is in the production of caprolactam, which is used in the manufacture of nylon-6 polymer.
• Chemical intermediate; a stabilizer and homogenizer for soaps and synthetic detergent emulsions; solvent for lacquers and varnishes.
