합성가스와 프로필렌을 원료로 하여 순도 99.5% 이상의 옥탄올.개요
n-Butyl alcohol is a colourless flammable liquid with strong alcoholic odour. n-Butyl alcohol is a highly refractive liquid and burns with a strongly luminous flame. It is incompatible with strong acids, strong oxidising agents, aluminium, acid chlorides, acid anhydrides, copper, and copper alloys. n-Butyl alcohol has an extensive use in a large number of industries. For instance, it is used as solvent in industries associated with the manufacturing of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. n-Butyl alcohol finds its use in the manufacture of artificial leather, rubber, plastic cements, shellac, raincoats, perfumes, and photographic films.화학적 성질
1-Butanol is a colorless, volatile liquid with a rancid sweet odor. The air odor threshold of 1-butanol was reported to be 0.83 ppm ; others have identified the minimum concentration with identifiable odor as 11 and 15 ppm.물리적 성질
Clear, colorless liquid with a rancid sweet odor similar to fusel oil. Experimentally determined detection and recognition odor threshold concentrations were 900 μg/m3 (300 ppbv) and 3.0 mg/m3 (1.0 ppmv), respectively (Hellman and Small, 1974). Odor threshold concentration in water is 500 ppb (Buttery et al., 1988). The least detectable odor threshold in concentration water at 60 °C was 0.2 mg/L (Alexander et al., 1982). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentrations ranging from approximately 900 to 4,000 ppm.출처
1-Butanol is a natural product found in Vitis rotundifolia, Cichorium endivia, peppermint oil from Brazil, Achillea ageratum, tea, apple aroma, American cranberry, black currants, guava fruit, papaya, cooked asparagus, tomato, Swiss cheese, Parmesan cheese, heated butter, cognac, Armagnac, rum and cider.용도
1-Butanol is used in the production of butylacetate, butyl glycol ether, and plasticizerssuch as dibutyl phthalate; as a solvent in thecoating industry; as a solvent for extractionsof oils, drugs, and cosmetic nail products;and as an ingredient for perfumes and flavor.1-Butanol occurs in fusel oil and as aby-product of the fermentation of alcoholicbeverages such as beer or wine. It is presentin beef fat, chicken broth, and nonfilteredcigarette smoke (Sherman 1979).
생산 방법
The principal commercial source of 1-butanol is n-butyraldehyde obtained from the oxo reaction of propylene, followed by hydrogenation in the presence of a catalyst . 1-Butanol has also been produced from ethanol via successive dehydrogenation to acetaldehyde, followed by an aldol process. The earliest commercial route to 1-butanol, which is still used extensively in many Third World countries, employs fermentation of molasses or corn products with Clostridium acetobutylicum .정의
ChEBI: 1-Butanol is a primary alcohol that is butane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It it produced in small amounts in humans by the gut microbes. It has a role as a protic solvent, a human metabolite and a mouse metabolite. It is a primary alcohol, a short-chain primary fatty alcohol and an alkyl alcohol.일반 설명
Colorless liquid. Used in organic chemical synthesis, plasticizers, detergents, etc.공기와 물의 반응
Highly flammable. Soluble in water.반응 프로필
1-Butanol attacks plastics. [Handling Chemicals Safely 1980. p. 236]. Mixtures with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. May form explosive butyl hypochlorite by reacting with hypochlorous acid. May form butyl explosive butyl hypochlorite with chlorine.위험도
Toxic on prolonged inhalation, irritant to eyes. Toxic when absorbed by skin. Flammable, moderate fire risk. Eye and upper respiratory tract irritant.건강위험
The toxicity of 1-butanol is lower than thatof its carbon analog. Target organs are theskin, eyes, and respiratory system. Inhalationcauses irritation of the eyes, nose, and throat.It was found to cause severe injury to rabbits’eyes and to penetrate the cornea uponinstillation into the eyes. Chronic exposureof humans to high concentrations may causephotophobia, blurred vision, and lacrimation.A concentration of 8000 ppm was maternallytoxic to rats, causing reduced weightgain and feed intake. Teratogenicity wasobserved at this concentration with a slightincrease in skeletal malformations (Nelsonet al. 1989).
In a single acute oral dose, the LD50 value(rats) is 790 mg/kg; in a dermal dose theLD50 value (rabbits) is 4200 mg/kg.
n-Butanol is oxidized in vivo enzymaticallyas well as nonenzymatically and iseliminated rapidly from the body in the urineand in expired air. It inhibits the metabolismof ethanol caused by the enzyme alcoholdehydrogenase.
Based on the available data, the useof n-butanol as an ingredient is consideredsafe under the present practices andconcentrations in cosmetic nail products(Cosmetic, Toiletry and Fragrance Association1987a).
화재위험
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.Safety Profile

Experimental reproductive Though animal experiments have shown the butyl alcohols to possess toxic properties, they have produced few cases of poisoning in industry, probably because of their low reported to have resulted in irritation of the eyes, with corneal inflammation, slight headache and H2ziness, slight irritation of the nose and throat, and dermatitis about fingers. Keratitis has also been reported. Mutation data reported.잠재적 노출

UN1120 Butanols, Hazard Class: 3; Labels: 3— Flammable liquid. UN1212 Isobutanol or Isobutyl alcohol, Hazard Class: 3; Labels: 3—Flammable liquidPurification Methods
Dry it with MgSO4, CaO, K2CO3, or solid NaOH, followed by refluxing with, and distillation from, small amounts of calcium, magnesium activated with iodine, or aluminium amalgam. It can also be dried with molecular sieves, or by refluxing with n-butyl phthalate or succinate. (For method, see Ethanol.) n-Butanol can also be dried by efficient fractional distillation, water passing over in the first fraction as a binary azeotrope (contains about 37% water). An ultraviolet-transparent distillate has been obtained by drying with magnesium and distilling from sulfanilic acid. To remove bases, aldehydes and ketones, the alcohol is washed with dilute H2SO4, then NaHSO4 solution; esters are removed by boiling for 1.5hours with 10% NaOH. It has also been purified by adding 2g NaBH4 to 1.5L butanol, gently bubbling with argon and refluxing for 1 day at 50o. Then adding 2g of freshly cut sodium (washed with butanol) and refluxed for 1day. Distil and collect the middle fraction [Jou & Freeman J Phys Chem 81 909 1977]. [Beilstein 1 IV 1506.]비 호환성
