1: Methanol, also known as methyl alcohol or wood alcohol, is a chemical compound with chemical formula CH3OH. It is the simplest alcohol, and is a light, volatile, colourless, tasteless, flammable, poisonous liquid with a very faint odor. It is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol. 2: Ethanol, also known as ethyl alcohol or grain alcohol, is a flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. In common parlance, it is often referred to simply as alcohol. Its chemical formula is C2H5OH, also written as C2H6O. 3: 1-Propanol is a primary alcohol with the formula CH3CH2CH2OH. It is also known as 1-propanol, 1-propyl alcohol n-propyl alcohol, or simply propanol. It is used as a solvent in the pharmaceutical industry, and for resins and cellulose esters. It is formed naturally in small amounts during many fermentation processes. 4: Butanol is a higher alcohol with a 4 carbon atom structure and a general formula of C4H10O. There are 4 different isomeric structures for butanol. These butanol isomers, due to their different structures, have somewhat different melting and boiling points. All are moderately miscible in water, less so than ethanol, and more so than the higher (longer carbon chain) alcohols. Like most alcohols, butanol is poisonous. 5: 1-Pentanol, or n-pentanol, is a higher alcohol with a five carbon atoms and a general formula of C5H11OH. 6: 1-Hexanol is an alcohol with a six carbon chain and the structural formula of CH3(CH2)5OH. It is a clear colorless liquid that is slightly soluble in water, but miscible with ether and ethanol. There are two isomers of hexanol, 2-hexanol and 3-hexanol, which differ by the location of the alcohol functional group.1-Hexanol is the compound that gives freshly mowed grass its smell. 7: 1-Heptanol is an alcohol with a seven carbon chain and the structural formula of CH3(CH2)6OH. It is a clear colorless liquid that is very slightly soluble in water, but miscible with ether and ethanol. There are two other isomers of heptanol, 2-heptanol and 3-heptanol, which differ by the location of the alcohol functional group.1-Heptanol has a pleasant smell and is used in cosmetics for its fragrance. 8: Octanol is a straight chain fatty alcohol with eight carbon atoms and the molecular formula CH3(CH2)7OH. Although the term octanol usually refers exclusively to the primary alcohol 1-octanol, there are other less common isomers of octanol such as the secondary alcohol, 2-octanol.Octanol occurs naturally in the form of esters in some essential oils. The primary use of octanol is in the manufacture of various esters (both synthetic and naturally occurring), such as octyl acetate, which are used in perfumery and flavors. 9: 1-Nonanol is a straight chain fatty alcohol with nine carbon atoms and the molecular formula CH3(CH2)8OH. It is a colorless to slightly yellow liquid with a citrus odor similar to citronella oil. Nonanol occurs naturally in the oil of orange. The primary use of nonanol is in the manufacture of artificial lemon oil. Various esters of nonanol, such as nonyl acetate, are used in perfumery and flavors. 10: 1-Decanol is a straight chain fatty alcohol with ten carbon atoms and the molecular formula CH3(CH2)9OH. It is a colorless viscous liquid that is insoluble in water.Decanol is used in the manufacture of plasticizers, lubricants, surfactants and solvents.
