tert-Butanol Chemical Properties,Uses,Production

Chemical Properties

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.

Uses

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

Uses

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

Definition

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.

General Description

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

Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

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].

Hazard

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

Health Hazard

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.

Health Hazard

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

Fire Hazard

Flash Point (°F): 52 ℃, 61 ℃; Flammable Limits in Air (%): 2.35-8.00; Fire Extinguishing Agents: Dry chemical, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 896; Electrical Hazard: Class I, Group D; Burning Rate: 3.4 mm/min.

Chemical Reactivity

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.

Safety Profile

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.

Potential Exposure

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.

First aid

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy

Purification Methods

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.

Incompatibilities

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
