The Cyclohexanol could be obtained by the method of phenol hydrogenation and cyclohexane oxidation: It could be made by the reactant of 1-cyclohexyloxy-1H-pyridine-2-thione. This reaction needs the reagents of tributylstannane, AIBN, and the solvent of benzene. The yield is 73 %. In addition, this reaction should be taken for 20 minutes at the temperature of 80 °C.
Uses of the Cyclohexanol: It's mainly used for the production of adipic acid, hexamethylene diamine, cyclohexanone, caprolactam and as a soap stabilizing agent, disinfection medicated soap and detergent emulsion. It's also used as solvents such as rubber, resins, nitrocellulose, metallic soaps, oils, esters, ethers. Paint blending agent, leather degreasing agent, release agent, dry cleaners, polishes are also made from the material of this chemical.
When you are using this chemical, please be cautious about it as the following: This chemical is harmful by inhalation and if swallowed. It's irritating to respiratory system and skin. Please avoid contact with skin and eyes.
