Isobutyl alcohol has a disagreeable odor. May be prepared from isobutylene; by reduction of isobutyraldehyde with sodium amalgam or in the presence of a catalyst; by fermentation of isobutyraldehyde; isolated during fermentation of carbohydrates.화학적 성질
Isobutyl alcohol has a penetrating, wine-like, disagreeable odor물리적 성질
Clear, colorless, oily liquid with a sweet, musty odor. Burning taste. The average least detectable odor threshold concentration in water at 60 °C was 0.36 mg/L (Alexander et al., 1982). Experimentally determined detection and recognition odor threshold concentrations were 2.0 mg/m3 (660 ppbv) and 5.4 mg/m3 (1.8 ppmv), respectively (Hellman and Small, 1974). An odor threshold concentration of 11 ppbv was reported by Nagata and Takeuchi (1990).출처

2-Methyl-1-propanol (Isobutyl alcohol) may be used to prepare the isobutyl alcohol-benzene solution for use in the quantification of inorganic phosphates. It may be used for the estimation of phosphate (inorganic phosphorous) by a colorimetric method.생산 방법
Isobutanol is commercially produced almost exclusively by the hydrogenation of isobutyraldehyde obtained from propylene using the oxo process.제조 방법
From isobutylene; by reduction of isobutyraldehyde with sodium amalgam or in the presence of a catalyst; by fermentation of isobutyraldehyde; isolated during fermentation of carbohydrates정의
ChEBI: Isobutanol is an alkyl alcohol that is propan-1-ol substituted by a methyl group at position 2. It has a role as a Saccharomyces cerevisiae metabolite. It is a primary alcohol and an alkyl alcohol. It derives from a hydride of an isobutane.일반 설명
A clear colorless liquid with a sweet odor. Flash point 85 - 100°F. Less dense than water. Vapors heavier than air.공기와 물의 반응
Highly flammable. Soluble in water.반응 프로필
2-Methyl-1-propanol 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. 2-Methyl-1-propanol is incompatible with strong oxidizers.위험도
Flammable, moderate fire risk. Strong irritant.건강위험
Inhalation causes eye and throat irritation andheadache. Ingestion may cause depression ofthe central nervous system. It is an irritantto the skin, causing cracking. Target organsare the eyes, skin, and respiratory system.LD50 value, oral (rabbits): 3750 mg/kg.
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.잠재적 노출
Butyl alcohols are used as solvents for paints, lacquers, varnishes, natural and synthetic resins, gums, vegetable oils, dyes, camphor, and alkaloids. They are also used as an intermediate in the manufacture of pharmaceuticals and chemicals; in the manufacture of artificial leather, safety glass; rubber and plastic cements, shellac, raincoats, photographic films, perfumes; and in plastic fabrication.Carcinogenicity
Nineteen Wistar rats were dosed with 0.2mL of isobutanol twice weekly by oral intubation. The average survival time was 495 days. It was reported that malignant tumors developed in three animals; one had a forestomach carcinoma and a liver cell carcinoma, another had a forestomach carcinoma and myelogenous leukemia, and the third, a myelogenous leukemia. In the same study, 24 rats were injected subcutaneously with 0.05 mL/kg twice weekly. The average survival time was 544 days. A total of eight malignant tumors developed: two forestomach carcinomas, two liver sarcomas, one spleen sarcoma, one mesothelioma, and two retroperitoneal sarcomas. Increased incidences of total tumors were observed by both routes of administration, but there was no significant increased incidence of any tumor type at any site. This study is considered inappropriate for cancer risk assessment.운송 방법
UN1120 Butanols, Hazard Class: 3; Labels: 3— Flammable liquid. UN1212 Isobutanol or Isobutyl alcohol, Hazard Class: 3; Labels: 3—Flammable liquidPurification Methods
Isobutanol is dried by refluxing with CaO and BaO for several hours, followed by treatment with calcium or aluminium amalgam, then fractional distilling it from sulfanilic or tartaric acids. More exhaustive purifications involve formation of phthalate or borate esters. Heating it with phthalic anhydride gives the acid phthalate which, after crystallisation to constant melting point (m 65o) from pet ether, is hydrolysed with aqueous 15% KOH. The alcohol is distilled off as the water azeotrope and dried (K2CO3, then anhydrous CuSO4), and finally magnesium turnings, followed by fractional distillation. [Hückel & Ackermann J Prakt Chem 136 15 1933.] The borate ester is formed by heating the dried alcohol for 6hours in an autoclave at 160-175o with a quarter of its weight of boric acid. After fractional distillation under vacuum, the ester is hydrolysed by heating for a short time with aqueous alkali and the alcohol is dried with CaO and distilled. [Michael et al. J Am Chem Soc 38 653 1916.] Alternatively dry the alcohol with K2CO3, CaSO4 or CaCl2, filter and fractionally distil it. For further drying, the redistilled alcohol can be refluxed with the appropriate alkyl phthalate or succinate as described under ethanol. [Beilstein 1 IV 1588.]비 호환성
Butyl alcohols may form explosive mixture with air. In all cases they are 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, oxoacids, epoxides. Attacks some plastics, rubber and coatings. n-Butanol is incompatible with strong acids; halogens, caustics, alkali metals; aliphatic amines; isocyanates. sec-Butanol forms an explosive peroxide in air. Ignites with chromium trioxide. Incompatible with strong oxidizers; strong acids; aliphatic amines; isocyanates, organic peroxides. tert-Butanol is incompatible with strong acids (including mineral acid), including mineral acids; strong oxidizers or caustics, aliphatic amines; isocyanates, alkali metals (i.e., lithium, sodium, potassium, rubidium, cesium, francium). isoButanol is incompatible with strong acids; strong oxidizers; caustics, aliphatic amines; isocyanates, alkali metals and alkali earth. May react with aluminum at high temperatur폐기물 처리
