Cyclohexanol Specification

This chemical has the IUPAC name Cyclohexanol,  and it's also named as 1-cyclohexanol. With the CAS registry number 108-93-0, its product categories are Essential Chemicals; Reagent Plus; Routine Reagents; Alcohols; C2 to C6; Oxygen Compounds and its classification codes are Human Data; Mutation data; Reproductive Effect; Skin / Eye Irritant; TSCA Flag T [Subject to the Section 4 test rule under TSCA]. However, this chemical is an alcohol and it should be stored in the cool and dry place. Keep it away from the oxides, heat, fire and acid.

Other characteristics of the Cyclohexanol can be summarised as followings: (1)ACD/LogP: 1.28; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.282; (4)ACD/LogD (pH 7.4): 1.282; (5)ACD/BCF (pH 5.5): 5.551; (6)ACD/BCF (pH 7.4): 5.551; (7)ACD/KOC (pH 5.5): 118.699; (8)ACD/KOC (pH 7.4): 118.699; (9)#H bond acceptors: 1; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 1; (12)Polar Surface Area: 20.23 Å2; (13)Index of Refraction: 1.478; (14)Molar Refractivity: 29.261 cm3; (15)Molar Volume: 103.441 cm3; (16)Polarizability: 11.6×10-24cm3; (17)Surface Tension: 32.496 dyne/cm; (18)Density: 0.968 g/cm3; (19)Flash Point: 67.778 °C; (20)Enthalpy of Vaporization: 46.14 kJ/mol; (21)Boiling Point: 159.552 °C at 760 mmHg; (22)Vapour Pressure: 0.876 mmHg at 25°C.

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.

Cyclohexanol could be made by the reactant of 1-cyclohexyloxy-1H-pyridine-2-thione

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.

You can still convert the following datas into molecular structure: 
1.SMILES: C1CCC(CC1)O
2.InChI: InChI=1/C6H12O/c7-6-4-2-1-3-5-6/h6-7H,1-5H2
