Types of Alcohol

1) Absolute alcohol: Absolute alcohol is a common name for the chemical compound ethanol. To qualify as “absolute,” the ethyl alcohol must contain no more than one percent water. In other words, absolute alcohol is liquid alcohol that is at least 99 percent pure alcohol by weight and it is preparedby two method: Azeotropic distillation:

a) Azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation . In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol.

2) Power alcohol (Gashol)

Gashol is a term used for the mixture of 10% ethyl alcohol (also called ethanol or grain alcohol) with gasoline . Ethanol raises the octane rating of lead-free automobile fuel and significantly decreases the carbon monoxide released from tailpipes.

3)Denatured alcohol:

The ethanol made unfit by adding poisonous substances like methyl alcohol along with coloring matter is known as denatured alcohol.

4. Rectified spirit:It is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. In some countries, denaturated alcohol or denatured rectified spirit may commonly be available as “rectified spirit“.

5.) Alcohol beverages: alcoholic beverage, any fermented liquor, such as wine beer or distilled sprit that contains ethyl alcohol or ethanol (CH3CH2OH), as an intoxicating agent.
