Anhydrous Ethanol (Ethanol absolute) refers to a higher purity of ethanol aqueous solution. Under normal circumstances, the concentration of 99.5% ethanol solution is generally called anhydrous ethanol, anhydrous ethanol is a mixture of ethanol and water.


Function and use

Ethanol is an important organic solvent, widely used in medicine, coatings, sanitary products, cosmetics, oils and other aspects, accounting for about 50% of the total consumption of ethanol. Ethanol is an important basic chemical raw material, used in the manufacture of acetaldehyde, ethylene, ethylamine, ethyl acetate, acetic acid, chloroethane, etc., and derived from medicine, dyes, coatings, spices, synthetic rubber, detergents, pesticides and other products of many intermediates, its products as many as 300 kinds, the use of ethanol as an intermediate of chemical products is gradually declining. Many products, such as acetaldehyde and acetic acid, no longer use ethanol as raw materials but other raw materials. 75% ethanol aqueous solution has a strong capacity and is commonly used as a disinfectant. Specially refined ethanol can also be used to make beverages. Like methanol, ethanol can be used as an energy source. Some countries have begun to use ethanol alone as vehicle fuel or mixed into gasoline (more than 10%) to save gasoline.
