Uses of Alcohol
Alcoholic Drinks: The term "alcohol" in alcoholic beverages refers to ethanol (CH3CH2OH).
Industrial methylated spirits: Ethanol is usually sold as industrial methylated spirits, which is ethanol with a small quantity of methanol and possibly some colour added. Because methanol is poisonous, industrial methylated spirits are unfit to drink, allowing purchasers to avoid the high taxes levied on alcoholic drinks.
Use of ethanol as a fuel:  Ethanol burns to produce carbon dioxide and water, as shown in the equation below, and can be used as a fuel in its own right or in mixtures with petrol (gasoline).

"Gasohol" is a petrol/ethanol mixture containing approximately 10–20% ethanol. Because ethanol can be produced by fermentation, this is a useful 
method for countries without an oil industry to reduce the amount of petrol imports.
Ethanol as a solvent: Ethanol is widely used as a solvent. It is relatively safe and can be used to dissolve many organic compounds that are insoluble in water. It is used, for example, in many perfumes and cosmetics.
Methanol as a fuel: Methanol also burns to form carbon dioxide and water: 2CH3OH+3O2→2CO2+4H2O
It can be used a petrol additive to improve combustion, and its use as a fuel in its own right is under investigation.
Methanol as an industrial feedstock: Methanol is also used to make other compounds, for example, methanal (formaldehyde), ethanoic acid, and methyl esters of various acids. In most cases, these are then converted into further products.
Terms related to alcohol
• Wood spirit: Methyl alcohol is also called wood spirit because in early stage it was obtained by the destructive distillation of wood.
• Grain alcohol: Ethyl alcohol is also called grain alcohol because it is obtained by the starch enriched substances.
• Absolute alcohol: The alcohol which is 100% pure is called absolute alcohol and it is completely pure and anhydrate.
• Rectified spirit: This is also called commercial alcohol in which 95.6% ethyl alcohol and 4.4% water exist.
• Power alcohol: The mixture of purified spirit, benzene and petrol is called power alcohol and it is used in propelling engine. As it is directly related to the power to carry out the engine so it is called power alcohol.
• Denatured alcohol: Ethyl alcohol which cannot be used for the beverage purposes is called denatured alcohol. To obtain such type of alcohol usually in purified spirit, methyl alcohol, piridin, acetone etc. type of toxic substances are mixed.
