Cyclohexanol Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Chemical Properties

Cyclohexanol is a sticky solid (above 25℃ /77℃ F) or colorless, viscous liquid. Faint camphor odor.

Physical properties

Clear, colorless to pale yellow, viscous, hygroscopic liquid with a camphor-like odor. A detection odor threshold concentration of 64 μg/m3 (155 ppbv) was reported by Punter (1983).

Uses

Solvent for alkyd resins, alcohol-sol phenolic resins, ethyl cellulose. manufacture of celluloid; finishing textiles; insecticides.

Uses

Cyclohexanol is used for the productionof adipic acid and caprolactam for makingnylon. Its phthalate derivatives are used forplasticizers. It is used as a stabilizer for soapsand detergents; as a solvent for lacquers,varnishes, and shellacs; and as a dye solventfor textiles.

Definition

ChEBI: An alcohol that consists of cyclohexane bearing a single hydroxy substituent. The parent of the class of cyclohexanols.

General Description

A colorless liquid with a camphor-like odor. Soluble in most organic liquids. Flash point 154°F. May be toxic by inhalation or skin exposure. Vapors are narcotic in high concentrations. Irritates skin, eyes and mucus membranes. Used in making soap, lacquers, and plastics.

Air & Water Reactions

Less dense than water and slightly soluble in water.

Reactivity Profile

Cyclohexanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Violent reaction with nitric acid. Incompatible with strong oxidizers (chromium trioxide, nitric acid, etc.).

Hazard

Toxic by ingestion.

Health Hazard

Narcosis-depression of the central nervous system tending to produce sleep or unconsciousness.

Health Hazard

Cyclohexanol is moderately toxic. Targetorgans are the eyes, skin, and respiratorysystem. At high concentrations cyclohexanolabsorbed through the skin may possiblyinjure the brain, kidney, and heart.
LD50 value, single oral dose (rats): 2060mg/kg
LD50 value, single intravenous dose (mice):270 mg/kg
Inhalation of vapors may cause irritationof the eyes, nose, and throat. However,because of its low vapor pressure (1.12 torrat 25°C), the health hazard due to inhalationis low. Ingestion can cause nausea,trembling, and gastrointestinal disturbances.Repeated skin contact may produce erythemaand edema.

Chemical Reactivity

Reactivity with Water: No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Potential Exposure

Cyclohexanol is used in making plac- ticizers, dry cleaning, dyebath; and textile finishing formu- lations; as a solvent for ethyl cellulose and other resins; it is used in soap manufacture; it is used as a raw material for adipic acid manufacture; as a nylon intermediate.

Environmental Fate

Biological. Reported biodegradation products include cyclohexanone (Dugan, 1972; Verschueren, 1983), 2-hydroxyhexanone, 1-oxa-2-oxocycloheptane, 6-hydroxyheptanoate, 6- oxohexanoate, and adipate (quoted, Verschueren, 1983). In activated sludge inoculum, following a 20-d adaptation period, 96.0% COD removal was achieved. The average rate of biodegradation was 28.0 mg COD/g?h (Pitter, 1976).
Photolytic. A photooxidation reaction rate constant of 1.74 x 10-13 cm3/molecule?sec was estimated for the reaction of cyclohexanol with OH radicals in the atmosphere (Atkinson, 1987).
Chemical/Physical. Cyclohexanol will not hydrolyze in water because it does not contain a hydrolyzable functional group (Kollig, 1993).
Complete combustion in air yields carbon dioxide and water vapor.

Shipping

UN1986 Alcohols, toxic, flammable, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poison Inhalation Hazard, Technical Name Required.

Purification Methods

Reflux it with freshly ignited CaO, or dry it with Na2CO3, then fractionally distil it. Redistil it from Na. It is further purified by fractional crystallisation from the melt in dry air. Peroxides and aldehydes can be removed by prior washing with ferrous sulfate and water, followed by distillation under nitrogen from 2,4-dinitrophenylhydrazine, using a short fractionating column: water distils as the azeotrope. Dry cyclohexanol is very hygroscopic. The 3,4-dinitrobenzoate has m 111-112o (EtOH or aqueous EtOH) It has TOXIC vapours. [Beilstein 6 III 10, 6 IV 20.]

Incompatibilities

Forms explosive mixture in air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoa- cids, epoxides. Attacks some plastics.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinera- tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
