2-Methyl-1-propanol Usage And Synthesis
IsobutanolIsobutanol, also known as isopropyl alcohol, 2-methyl propanol is a colorless alcohol flammable liquid. Isobutanol is one of the main ingredients of fresh tea leaves, black tea and green tea to produce the wonderful aroma with the molecular weight of 74.12, boiling point of 107.66 ℃, relative density of 0.8016 (20/4 ℃), refractive index of 1.3959 and a flash point of 37 ℃. Isobutanol is fully dissolved in alcohol and ether, slightly soluble in water. Its vapor can form an explosive mixture with air; the explosion limit is 2.4% (volume). It can form addition compounds (CaCl2 • 3C4H10O) with calcium chloride. Isobutanol can be obtained by the distillation of the by-product of methanol and can also be derived from distillation of crude fusel oil. Using Industrial carbonyl cobalt as a catalyst, making propylene and carbon monoxide and hydrogen mixture react at 110~140 ° C, 2.0265 × 107~3.0397 × 107Pa to generate butyraldehyde and isobutyraldehyde, and then via catalytic hydrogenation, separation can obtain isobutanol. Isobutanol is used in the manufacture of petroleum additives, antioxidants, plasticizers, synthetic rubber, artificial musk, fruit oil and synthetic drugs and also used as solvents and chemical reagents.
Chemical propertiesIt is a kind of colorless transparent liquid with a special smell, soluble in water, and fully dissolved in ethanol and ether.
Uses(1)  For analysis reagents, chromatography reagents, solvents and extraction agent.
(2)  As raw materials for the organic synthesis, and also act as a superior solvent.
(3)  Isobutanol is raw materials for organic synthesis. It mainly used in the synthesis of isobutyronitrile, an intermediate for diazinon.
(4)  As raw materials of organic synthesis, isobutanol is used in the manufacture of petroleum additives, antioxidants, 2, 6-butylated hydroxytoluene, isobutyl acetate (paint solvents), plasticizers, synthetic rubber, artificial musk, fruit oil and synthetic drugs. It can also be used to purify strontium, barium and lithium salts and other chemical reagents and used as a superior solvent.
(5)  Extraction solvent. Food flavors listed in GB 2760-96.
Production method(1) In the presence of sodium amalgam or other catalysts, it is derived from the reduction of butyraldehyde;r it is derived from the distillation of the by-product obtained from the synthesis of methanol.
(2) 1. Carbonyl synthesis (by-product of butanol production from propylene) : using propylene and synthesis gas as raw material, going through  carbonyl synthesis in the system to get  n-butyl and isobutyl  aldehyde, after the catalyst, hydrogenating into alcohol, then undergoing dehydration and separation can obtain the product of   n-butyl and isobutyl  alcohol respectively.
2. Hydrogenation of isobutyraldehyde: isobutyraldehyde via the liquid hydrogenation reaction, obtained isobutanol in the catalytic nickel.
3. Recycle from isobutyl oil, a byproduct of synthetic methanol distillation: isobutanol is obtained by dehydration of methanol, salting out and then azeotropic distillation of isobutyl oil.
(3) The preparation method is using synthesis gas and propylene as raw materials, obtaining isobutyraldehyde during the carbonyl synthesis of 2-ethylhexyl alcohol, and then by hydrogenation to acquire isobutanol.

General DescriptionA clear colorless liquid with a sweet odor. Flash point 85 - 100°F. Less dense than water. Vapors heavier than air.
Air & Water ReactionsHighly flammable. Soluble in water.
Reactivity Profile2-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.
HazardFlammable, moderate fire risk. Strong irritant.
Health HazardContact with eyes is extremely irritating and may cause burns. Breathing vapors will be irritating to the nose and throat. In high concentrations, may cause nausea, dizziness, headache, and stupor.
Fire HazardHIGHLY 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.
Fire HazardFlash Point (°F): 82 ℃, 90 ℃; Flammable Limits in Air (%): 1.6-10.9; Fire Extinguishing Agents: Alcohol foam, dry chemical, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 800; Electrical Hazard: Not pertinent; Burning Rate: 3.5 mm/min.

Potential ExposureButyl 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 aidMove 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 MethodsIsobutanol 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.]
IncompatibilitiesButyl 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.
