1. Introduction
Ethanol, also known as ethyl alcohol, ethyl alcohol, grain alcohol or alcohol, is an organic compound in the homologous series of alcohols, flammable, colorless, one of the common alcohols found in portion of alcoholic beverages.
Chemical formula: C2H5OH or C2H6O
CAS Code: 64-17-5.
Origin: Vietnam.
Packing: 210 Lit/drum.
2. Properties
Ethanol is a colorless, volatile liquid with a characteristic odor. When burned with a smokeless blue flame, it forms carbon dioxide and water.
Ethanol solvent has a lighter density than water (Density to water: 0.7936 g/ml at 15oC).
Concentration: 96%
Ethanol is a mobile solvent, soluble in water with other organic compounds: acetic acid, acetone, benzene, carbon tetrachloride, chloroform, diethyl ether, ethylene glycol, glycerin, nitromethane, pyridine and toluene. Mixtures can be made with aliphatic hydrocarbons such as pentane and hexane and with aliphatic chlorides such as trichloroethane and tetraloethylene.
3. Production
Ethanol is produced by fermenting naturally occurring carbohydrate sources such as wheat, barley, sugar, corn, cassava, humus, wood, etc.
Another way, in the petrochemical synthesis technology, Ethanol is prepared by the technology line of hydration of ethylene gas with an acid catalyst.
In addition, it is also prepared through the purification pathway between ethanol and water.
4. Application
As fuel or petroleum additive:
Ethanol can be used as an alcohol fuel (usually mixed with gasoline) and in a variety of other industrial processes.
– A mixture of gasoline (90%) and ethanol (10%) is usually prepared by fermenting agricultural products or gasoline (97%) with methanol (or alcohol).
Ethanol is used in antifreeze products because of its low freezing point
Material
– In industry, Ethanol is used as a raw material to produce other organic compounds such as diethyl ether, acetic acid, etc.
Acoholic drink
– Ethanol is alcohol, so it is the main ingredient for making alcoholic beverages. At that time, Ethanol will be metabolized as an energy to provide nutrients. Especially good for the digestive system if taken in moderate amounts.
Making solvents
– Most of the ethanol is used as a solvent in the pharmaceutical, perfumery, printing, paint, electronics, textile, and pharmaceutical industries.
Disinfectant cleaning
– Ethanol alcohol is widely used in medicine with anti-bacterial and anti-microbial effects.
– In particular, people also use Ethanol (70 – 90%) to sterilize equipment, tools, wounds, … Because it has high antiseptic properties.
In the pharmaceutical industry
– Ethanol is also used to produce sleeping pills because it can cause anesthesia, causing drowsiness for users. If the blood alcohol concentration exceeds 5%, it can be life-threatening.
