化学的特性

Butyl alcohol, also known as butanol, exists in three isomeric alcohols that are toxic and soluble in most organic liquids. n-butyl alcohol, CH3(CH2)2CH20H, also known as l-butanol, propyl carbinol, and prim-butyl alcohol, is a colorless liquid. It is used in manufacturing perfumes and lacquers. sec-butyl alcohol, CH3CH2CHOHCH3, also known as 2-butanol, ethyl-methyl carbinol, butylene hydrate, and 2-hydroxy butane, is a colorless liquid. It is used in the preparation of fruit essence. tert-butyl alcohol, (CH3)3COH, also known as 2-methyl 2-propanol and trimethyl carbinol, is a colorless liquid.

物理的性質

Colorless liquid or crystals with a camphor-like odor. A detection odor threshold concentration of 2,900 mg/m3 (957 ppmv) was experimentally determined by Dravnieks (1974). In a later study, Nagata and Takeuchi (1990) reported an odor threshold concentration 220 ppbv.

使用

tert-Butyl alcohol is used in the productionof tert-butyl chloride, tert-butyl phenol, andisobutylene; in the preparation of artificialmusk; and in denatured alcohols.

使用

Denaturant for ethanol, manufacturing flotation agents, flavors, perfumes; as solvent; in paint removers. Octane booster in gasoline.

定義

butanol: Either of two aliphaticalcohols with the formula C4H9OH.Butan-1-ol, CH3(CH2)3OH, is aprimary alcohol; r.d. 0.81; m.p.–89.5°C; b.p. 117.3°C. Butan-2-ol,CH3CH(OH)C2H5, is a secondary alcohol;r.d. 0.81; m.p. –114.7°C; b.p.100°C. Both are colourless volatileliquids obtained from butane and areused as solvents.

一般的な説明

Colorless oily liquid with a sharp alcohol odor. Floats and mixes with water. Produces irritating vapor. Freezing point is 78°F.

空気と水の反応

Highly flammable. Water soluble.

反応プロフィール

Attacks plastics. [Handling Chemicals Safely 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenylm-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73 1967; J, Org. Chem. 28:1893 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

危険性

Irritant to eyes and skin. Flammable, dan- gerous fire risk. Central nervous system impair- ment. Questionable carcinogen.

健康ハザード

tert-Butyl alcohol is more toxic than secbutylalcohol but less toxic than the primaryalcohol. However, its narcotic actionis stronger than that of n-butanol. Inhalationmay cause drowsiness and mild irritationof the skin and eyes. Ingestion may produceheadache, dizziness, and dry skin.
Acute oral LD50 value (rats): 3500 mg/kg.

健康ハザード

Vapor is narcotic in action and irritating to respiratory passages. Liquid is irritating to skin and eyes.

化学反応性

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

安全性プロファイル

Moderately toxic by ingestion, intravenous, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. Dangerous fire hazard when exposed to heat or flame. Moderately explosive in the form of vapor when exposed to flame. Ignites on contact with potassium-sodum alloys. To fight fire, use alcohol foam, CO2, dry chemical. Incompatible with oxidizing materials, H202. See also n-BUTYL ALCOHOL and ALCOHOLS.

職業ばく露

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.

Source

Detected in a distilled water-soluble fraction of 94 octane unleaded gasoline at a concentration of 3.72 mg/L (Potter, 1996)

環境運命予測

Biological. Bridié et al. (1979) reported BOD and COD values of 0.02 and 2.49 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d. The ThOD for tert-butyl alcohol is 2.59 g/g. In activated sludge inoculum, 98.5% COD removal was achieved. The average rate of biodegradation was 30.0 mg COD/g?h (Pitter, 1976).
Bradley et al. (1999) studied the degradation of tert-butyl alcohol by indigenous microorganisms in stream-bed sediments from underground gasoline spill sites in Laurens, SC (Laurens) and Charleston, SC (Oasis). Under aerobic conditions, the amount of tert-butyl alcohol mineralizing to carbon dioxide after 27 d was 70% in both Laurens and Oasis sediments. After 80 d, the amount of mineralization reached an asymptiotic level of approximately 84%. No mineralization of tert-butyl alcohol was observed under strictly anaerobic conditions.
Photolytic. Wallington (1988c) reported a rate constant of 1.07 x 10-12 cm3/molecule?sec at 298 K. Based on an atmospheric OH concentration of 1.0 x 106 molecule/cm3, the reported half-life of tert-butyl alcohol is 8.6 d (Grosjean, 1997).
Chemical/Physical. May react with strong mineral acids (e.g., hydrochloric) or oxidizers releasing isobutylene (NIOSH, 1997).
tert-Butyl alcohol will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1993).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in effluent concentration of 705 mg/L. The adsorbability of the carbon used was 59 mg/g carbon (Guisti et al., 1974).

純化方法

It is synthesised commercially by the hydration of 2-methylpropene in dilute H2SO4. Dry it with CaO, K2CO3, CaSO4 or MgSO4, filter and fractionally distil it. Dry further by refluxing with, and distilling from, either magnesium activated with iodine, or small amounts of calcium, sodium or potassium, under nitrogen. Passage through a column of type 4A molecular sieve is another effective method of drying; as well as refluxing with tert-butyl phthalate or succinate. (For method see Ethanol.) Other methods include refluxing with excess aluminium tert-butylate, or standing with CaH2, and distilling as needed. Further purification is achieved by fractional crystallisation by partial freezing, taking care to exclude moisture. tert-Butyl alcohol samples containing much water can be dried by adding *benzene, so that the water distils off as a tertiary azeotrope, b 67.3o. Traces of isobutylene have been removed from dry tert-butyl alcohol by bubbling dry pre-purified nitrogen through for several hours at 40-50o before using. It forms azeotropic mixtures with a large number of compounds. It has also been purified by distillation from CaH2 into Linde 4A molecular sieves which had been activated at 350o for 24hours [Jaeger et al. J Am Chem Soc 101 717 1979]. [Beilstein 1 IV 1609.] Rapid purification: Dry tert-butanol over CaH2 (5% w/v), distil and store it over 3A molecular sieves.

不和合性

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 temperatur
