Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug, best known as the type of alcohol found in alcoholic beverages. While it was a common primary fuel in early liquid-fuel rocket motors, it is widely used as a fuel additive, and is extensively used as a solvent.
Ethanol is a straight-chain alcohol, and its chemical formula is C2H5OH (or CH3-CH2-OH). It has a molecular mass of 46.07 and a normal boiling point of 78.32 °C.
Health effects
Harmful
Heavy drinking can lead to alcohol withdrawal when drinking is stopped.
Beneficial
Moderate drinking is associated with reduced cardiac morbidity. Starting moderate drinking during middle age is also associated with cardiovascular benefits and reduced total mortality.[1].[2]
