Alcohols, in various forms, are used within medicine as antiseptics, disinfectants, and as an antidote. Taken by mouth or injected into a vein it is used to treat methanol or ethylene glycol toxicity when fomepizole is not available. Types of alcohol used include ethanol, denatured ethanol, 1-propanol, and isopropyl alcohol. It is effective against a range of microorganisms though does not inactivate spores. Concentrations of 60 to 90% work best. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is about 1.80 to 9.50 USD per litre of 70% denatured ethanol. In the United Kingdom it costs the NHS about 3.90 pound per liter of 99% denatured alcohol.

Isopropyl alcohol (IUPAC name propan-2-ol), also called isopropanol or dimethyl carbinol, is a compound with the chemical formula C3H8O or C3H7OH or CH3CHOHCH3 (sometimes represented as i-PrOH). It is a colorless, flammable chemical compound with a strong odor. As a propyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms, sometimes shown as (CH3)2CHOH. It is a structural isomer of 1-propanol. It has a wide variety of industrial and household uses.

Methanol, also known as methyl alcohol and wood alcohol, is the simplest of the alcohols. The name is derived from the Greek words "methy" (wine) and "hule" (wood). Methanol is is found in wood smoke, and contributes to the odor of wine. It is metabolized in the body to produce formaldehyde and formic acid, and is toxic if more than 50 mL is consumed; smaller amounts can cause blindness.
Industrially, methanol is produced from synthesis gas, a mixture of carbon monoxide and hydrogen derived from coke (the coal, not the soda) or methane. Methanol is used as the fuel in some racing cars, and is being investigated as an renewable alternative to the use of petroleum-based fuels. The main use of methanol, however, is in the manufacture of other chemicals, such as formaldehyde, which is used in the manufacture of plastics, paints, plywood, etc.
Ethanol, also known as ethyl alcohol and grain alcohol, is the alcohol found in alcoholic beverages. The fermentation of the sugars found in honey, grain, or fruit juices by yeasts to yield beers and wines was probably the first chemical reaction to be discovered.
Ethanol can be purified and concentrated by fractional distillation, but ethanol and water form an constant-boiling azeotrope at a concentration of 95% ethanol and 5% water which cannot be separated by distillation; absolute ethanol, which contains no water, is produced by fractional distillation of 95% ethanol with small amounts of benzene. Ethanol that is intended for industrial use is "denatured" (rendered unfit for human consumption) by adding small amounts of methanol, denatonium benzoate, or other unpleasant or toxic substances, which exempts the alcohol from liquor taxes.
Ethanol is metabolized in the body, primarily by the enzyme alcohol dehydrogenase, to produce acetaldehyde; the buildup of acetaldehyde in the blood is one of the factors which contributes to the symptoms of a hangover. Physiologically, ethanol acts as a depressant, but since it frees parts of the cortex from inhibitory controls, to its consumer, it seems to be a stimulant.
Ethanol is a primary (1º) alcohol, and is easily oxidized by mild oxidizing agents, such as chromic acid (H2CrO4) or potassium dichromate (K2Cr2O7), in which the chromium is in the +6 oxidation state. These substances undergo a distinct color change on reaction with ethanol: in the +6 oxidation state chromium compounds are typically a dark reddish-orange color; after the alcohol is oxidized, the chromium is reduced to the +3 oxidation state, which is green. The color change from red-orange to green forms the basis of some of the simple breathalyzer tests that are used to test motorists who are suspected of driving while drunk.
Ethanol can also be oxidized in air, forming acetic acid, the active ingredient in vinegar. Alcoholic beverages that are not stored properly can end up tasting like vinegar because of the formation of acetic acid (see entry for acetic acid).
1-Propanol, or propyl alcohol, is a three-carbon alcohol with the OH group on an end carbon. Its structural isomer, 2-propanol, is described below.
2-Propanol, or isopropyl alcohol, is a three-carbon alcohol with the OH group on the middle carbon. Isopropyl alcohol is a secondary alcohol, Rubbing alcohol is a solution of 70% isopropyl alcohol and 30% water, which is commonly used in sterilizing swabs and disinfectants.
Isopropyl alcohol is a secondary (2º) alcohol, and is easily oxidized by mild oxidizing agents.
1-Butanol, or butyl alcohol, is a four-carbon chain, with the OH group on an end carbon. It is used as a solvent and a paint thinner, and has some potential use as a biofuel.
Butyl alcohol is a primary (1º) alcohol, and is easily oxidized.
There are three other structural isomers of 1-butanol: 2-butanol (sec-butyl alcohol), 2-methyl-1-propanol (isobutyl alcohol), and 2-methyl-2-propanol (tert-butyl alcohol).
2-Butanol, or sec-butanol, or sec-butyl alcohol, or s-butyl alcohol, is a four-carbon chain, with the OH group on the second carbon. (Since the alcoholic carbon is connected to two other carbons, it is secondary, hence the prefix "sec".) It is used as a solvent and an intermediate in the manufacture of other compounds.
sec-Butyl alcohol is a secondary (2º) alcohol, and is easily oxidized.
2-Butanol is a chiral compound, and exists in two enantiomeric forms: (R)-2-butanol and (S)-2-butanol:
2-Methyl-1-propanol, or isobutanol, or isobutyl alcohol, is a three-carbon chain, with the OH group on and end carbon and a methyl group on the middle carbon. It is used as a solvent, in paints and inks, and in the manufacture of some coatings and varnishes.
Isobutyl alcohol is a primary (1º) alcohol, and is easily oxidized.
2-Methyl-2-propanol, or tert-butanol, or tert-butyl alcohol, or t-butyl alcohol, is a three-carbon chain, with the OH group and a methyl group on the middle carbon. (Since the alcoholic carbon is connected to three other carbons, it is tertiary, hence the prefix "tert".) It is used as a solvent, a denaturant for ethanol, as an octane booster in gasoline, and in some pain thinners.
tert-Butyl alcohol is a tertiary (3º) alcohol, and does not react with oxidizing agents. It is useful in organic synthesis, in the form of the t-butoxide anion, which is generated by the reaction of tert-butanol with sodium or a strong base such as sodium hydride, which removes the slightly acidic hydrogen from the OH group, leaving behind a negative charge on the oxygen. The t-butoxide anion is a strong base, but its steric bulk makes it slow to participate in nucleophilic substitution reactions, making it more likely to participate in elimination reactions.
Ethylene glycol is produced industrially from ethylene: the ethylene is oxidized to form ethylene oxide, which reacts with water to produce ethylene glycol. It is used in the manufacture of they polyester polyethylene terephthalane (PET), and also to remove water vapor from natural gas.
Ethylene glycol is used in antifreeze — pure ethylene glycol freezes at -12.9°C (8.8°F), but a 50:50 mixture of ethylene glycol and water freezes at around -40°C (-40°F). It is also used as an airplane de-icer, a humectant (an anti-drying agent that keeps other substances moist), used in ball point pen inks.
Ethylene glycol is toxic; in the body it is metabolized into glycolic acid (if one alcohol group is oxidized to a carboxylic acid) and oxalic acid (if both alcohol groups are oxidized), which can cause irregular heartbeat and respiration, and kidney failure. The antidote for ethylene glycol poisoning is ethanol: since ethanol competes for the same alcohol dehydrogenase enzyme that metabolizes ethylene glycol, flooding the body with alcohol can help to flush the ethylene glycol out of the system.
1,2-Propanediol, or propylene glycol, is a tasteless, odorless, clear liquid. Like ethylene glycol, it is miscible with water, because of hydrogen bonding. It is used in antifreeze, as a moisturizer in lotions, foods, and some medicines and cosmetics, and as a solvent for food dyes. It is also used to make artificial smoke.
1,2,3-Propanetriol, better known as glycerol or glycerin, is a viscous, colorless, odorless, sweet-tasting liquid. It is used as an emollient (softening agent) in cosmetics; as a humectant (anti-drying agent) in toothpaste, candies, medicines, tobacco (where it keeps leaves from drying and crumbling), and glues (prevent glue from drying in the bottle). It is also used in some plastics, especially cellophane, as a plasticizer to keep the plastic soft and pliable. Glycerol also contributes to the sweet, smooth taste of some wines. Because it can form three sets of hydrogen bonds, it is extremely soluble in water, and has a very high boiling point (290°C).
Glycerol combines with fatty acids (long-chain carboxylic acids) to make an series of biologically important molecules called the triglycerides (fats and oils).
Benzyl alcohol, or phenylmethanol, is used in perfumes, flavors, soaps, cosmetics, ointments, and ball point pen inks; it is also used in some anti-itching medications.
Cinnamic alcohol, or cinnamyl alcohol, is found in cinnamon leaves (hence the name), usually in the form of an ester; it is also found in Tolu balsam, the resin of the Myroxylon toluifera tree. It has an odor similar to that of hyacinth, and is used in perfumes (particularly in lilac and other floral scents), deodorants, flavoring agent, soaps, and cosmetics.
In 1937, the S.E. Massengill Co. marketed sulfanilamide (a sulfa drug) dissolved in diethylene glycol as "Elixir Sulfanilamide"; over a hundred people died of poisoning by the DEG, and this incident catalyzed the passage of the 1938 Federal Food, Drug, and Cosmetic Act, which greatly expanded the power of the Food and Drug Administration (FDA) to regulate the safety of foods, medicines, and cosmetics. Several other cases of DEG poisoning have resulted from DEG either being added to wines in an attempt to sweeten them, or because of its presence in improperly purified medications and cosmetics. In May of 2007, several cheap brands of toothpaste originating in China were removed from the market in several countries because they were found to be contaminated with DEG (labeled on the containers as "glycerine").
Cyclohexanol is a cyclic, secondary alcohol. It is used in some organic synthesis reactions, in the manufacture of celluloid, textiles, and some insecticides.

Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammablechemical compound (chemical formula CH3CHOHCH3) with a strong odor. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether.
It is used in the manufacture of a wide variety of industrial and household chemicals and is a common ingredient in chemicals such as antiseptics, disinfectants, and detergents.
Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins. Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. The process is colloquially called salting out, and causes concentrated isopropyl alcohol to separate into a distinct layer.
Isopropyl alcohol forms an azeotrope with water, which gives a boiling point of 80.37 °C (176.67 °F) and a composition of 87.7% by mass (91% by volume) isopropyl alcohol. Water–isopropyl alcohol mixtures have depressed melting points. It has a slightly bitter taste, and is not safe to drink.
Isopropyl alcohol becomes increasingly viscous with decreasing temperature and freezes at −89 °C (−128 °F).
Isopropyl alcohol has a maximal absorbance at 205 nm in an ultraviolet–visible spectrum.
Isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. This can be achieved using oxidizing agents such as chromic acid, or by dehydrogenation of isopropyl alcohol over a heated copper catalyst:
- (CH3)2CHOH → (CH3)2CO + H2
Isopropyl alcohol is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions. Isopropyl alcohol may be converted to 2-bromopropane using phosphorus tribromide, or dehydrated to propene by heating with sulfuric acid.
Like most alcohols, isopropyl alcohol reacts with active metals such as potassium to form alkoxides that can be called isopropoxides. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.
In 1920, Standard Oil first produced isopropyl alcohol by hydrating propene. Isopropyl alcohol was oxidized to acetone for the preparation of cordite, a smokeless, low explosive propellant.
In 1994, 1.5 million tonnes of isopropyl alcohol were produced in the United States, Europe, and Japan. It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. There are two routes for the hydration process and both processes require that the isopropyl alcohol be separated from water and other by-products by distillation. Isopropyl alcohol and water form an azeotrope, and simple distillation gives a material that is 87.9% by mass isopropyl alcohol and 12.1% by mass water. Pure (anhydrous) isopropyl alcohol is made by azeotropic distillation of the wet isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.
Small amounts of isopropyl alcohol are produced in the body in diabetic ketoacidosis.
Indirect hydration reacts propene with sulfuric acid to form a mixture of sulfate esters. This process can use low-quality propene, and is predominant in the USA. These processes give primarily isopropyl alcohol rather than 1-propanol, because adding water or sulfuric acid to propene follows Markovnikov's rule. Subsequent hydrolysis of these esters by steam produces isopropyl alcohol, by distillation. Diisopropyl ether is a significant by-product of this process; it is recycled back to the process and hydrolyzed to give the desired product.
- CH3CH=CH2 + H2O H2SO4⟶ (CH3)2CHOH

Direct hydration reacts propene and water, either in gas or liquid phase, at high pressures in the presence of solid or supported acidic catalysts. This type of process usually requires higher-purity propylene (> 90%). Direct hydration is more commonly used in Europe.
Hydrogenation of acetone
Isopropyl alcohol may be prepared via the hydrogenation of acetone, however this approach involves an extra step compared to the above methods, as acetone is itself normally prepared from propene via the cumene process. It may remain economical depending on the value of the products. A known issue is the formation of MIBK and other self-condensation products. Raney nickel was one of the original industrial catalysts, modern catalysts are often supported bimetallic materials. This is an efficient process and easy
In 1990, 45,000 metric tonnes of isopropyl alcohol were used in the United States, mostly as a solvent for coatings or for industrial processes. In that year, 5400 metric tonnes were used for household purposes and in personal care products. Isopropyl alcohol is popular in particular for pharmaceutical applications, due to its low toxicity. Some isopropyl alcohol is used as a chemical intermediate. Isopropyl alcohol may be converted to acetone, but the cumene process is more significant. 
Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. Together with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents.
Isopropyl alcohol is commonly used for cleaning eyeglasses, electrical contacts, audio or video tape heads, DVD and other optical disc lenses, removing thermal paste from heatsinks on CPUs and other IC packages.
Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide and sodium hydroxide to give sodium isopropylxanthate, a herbicide and an ore flotation reagent. Isopropyl alcohol reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides, respectively, the former a catalyst, and the latter a chemical reagent. This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation.
Rubbing alcohol, hand sanitizer, and disinfecting pads typically contain a 60–70% solution of isopropyl alcohol or ethanol in water. Water is required to open up membrane pores of bacteria, which acts as a gateway for isopropyl alcohol. A 75% v/v solution in water may be used as a hand sanitizer. Isopropyl alcohol is used as a water-drying aid for the prevention of otitis externa, better known as swimmer's ear.
Early uses as an anesthetic
Although isopropyl alcohol can be used for anesthesia, its many negative attributes or drawbacks prohibit this use. Isopropyl alcohol can also be used similarly to either as a solvent or as an anesthetic by inhaling the fumes or orally. Early uses included using the solvent as general anesthetic for small mammals and rodents by scientists and some veterinarians. However, it was soon discontinued, as many complications arose, including respiratory irritation, internal bleeding, and visual and hearing problems. In rare cases, respiratory failure leading to death in animals was observed.
Isopropyl alcohol is a major ingredient in "gas dryer" fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from gasoline and can freeze in the supply lines at low temperatures. Alcohol does not remove water from gasoline, but the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water, as it no longer accumulates in the supply lines and freezes but is dissolved within the fuel itself. Isopropyl alcohol is often sold in aerosol cans as a windshield or door lock deicer. Isopropyl alcohol is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4, or mineral oil) does not contaminate the brake pads and cause poor braking. Mixtures of isopropyl alcohol and water are also commonly used in homemade windshield washer fluid.
As a biological specimen preservative, isopropyl alcohol provides a comparatively non-toxic alternative to formaldehyde and other synthetic preservatives. Isopropyl alcohol solutions of 70–99% are used to preserve specimens.
Isopropyl alcohol is often used in DNA extraction. A lab worker adds it to a DNA solution to precipitate the DNA, which then forms a pellet after centrifugation. This is possible because DNA is insoluble in isopropyl alcohol.
Isopropyl alcohol vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. It should be kept away from heat and open flame. Distillation of isopropyl alcohol over magnesium has been reported to form peroxides, which may explode upon concentration. Isopropyl alcohol causes eye irritation and is a potential allergen. Wearing protective gloves is recommended.
Isopropyl alcohol, via its metabolites, is somewhat more toxic than ethanol, but considerably less toxic than ethylene glycol or methanol. Death from ingestion or absorption of even relatively large quantities is rare. Both Isopropanol and its metabolite, acetone, act as central nervous system (CNS) depressants. Poisoning can occur from ingestion, inhalation, or skin absorption. Symptoms of isopropyl alcohol poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, hypothermia, low blood pressure, shock, respiratory depression, and coma. Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone. Isopropyl alcohol does not cause an anion gap acidosis, but it produces an osmolal gap between the calculated and measured osmolalities of serum, as do the other alcohols.
Isopropyl alcohol is oxidized to form acetone by alcohol dehydrogenase in the liver and has a biological half-life in humans between 2.5 and 8.0 hours. Unlike methanol or ethylene glycol poisoning, the metabolites of isopropyl alcohol are considerably less toxic, and treatment is largely supportive. Furthermore, there is no indication for the use of fomepizole, an alcohol dehydrogenase inhibitor, unless co-ingestion with methanol or ethylene glycol is suspected.
In forensic pathology, people who have died as a result of diabetic ketoacidosis usually have blood concentrations of isopropyl alcohol of tens of mg/dL, while those by fatal isopropyl alcohol ingestion usually have blood concentrations of hundreds of mg/dL.
