사이클로헥산올 C화학적 특성, 용도, 생산

물성

화학식 C6H12O. 무색의 점성 액체로서 분자량 100.2, 녹는점 23℃, 끓는점 161℃이다. 장뇌(樟腦)와 같은 냄새가 난다. 가연성이 있으며 피부를 자극하고 산화제와 격렬히 반응하므로 취급할 때 주의를 요한다. 물에는 미량이 녹고, 보통의 유기용매에 녹는다. 크로뮴산에 의해 사이클로헥사논으로 산화될 수 있다. 페놀의 접촉수소첨가 또는 시클로헥사논을 환원시켜서 만든다. 나일론의 중간 원료, 에멀션화제, 용제로 쓰인다.

화학적 성질

colourless liquid

화학적 성질

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

물리적 성질

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).

용도

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

용도

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.

정의

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

일반 설명

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.

공기와 물의 반응

Less dense than water and slightly soluble in water.

반응 프로필

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.).

위험도

Toxic by ingestion.

건강위험

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

건강위험

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.

화학 반응

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.

잠재적 노출

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.

환경귀착

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.

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.]

비 호환성

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.

폐기물 처리

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.
