Ethanol, also known as ethyl alcohol, is a clear, colorless liquid with the chemical formula $$C_2H_5OH$$ and a CAS number of64-17-5. It is widely recognized for its use in alcoholic beverages, as well as in various industrial applications.
Chemical Properties
Molecular Formula: $$C_2H_5OH$$- Boiling Point:78.5 °C (173.3 °F)
Melting Point: -114.5 °C- Density: Approximately0.789 g/mL at20 °C- Solubility: Highly soluble in water and many organic solvents, but poorly soluble in fats and oils.
Ethanol is a volatile and flammable liquid, which can form explosive mixtures with air. It has a characteristic odor and a burning taste when concentrated, but it is somewhat sweet when diluted.
Production Methods
Ethanol can be produced through two primary methods:
Fermentation: This biological process involves the conversion of carbohydrates (such as sugars from crops like corn and sugarcane) into ethanol by yeast. This method is commonly used for producing alcoholic beverages.
Hydration of Ethylene: This chemical process involves reacting ethylene with steam in the presence of a catalyst to produce ethanol. This method is typically used for industrial ethanol production.
Uses
Ethanol has a wide range of applications, including:
Alcoholic Beverages: It is the intoxicating ingredient in drinks like beer, wine, and spirits.
Industrial Solvent: Used in the manufacturing of paints, cosmetics, and pharmaceuticals.
Fuel Additive: Ethanol is blended with gasoline to create fuels like E10, E15, and E85, which are used in flexible fuel vehicles.
Disinfectant: Due to its bactericidal properties, ethanol is often used in hand sanitizers and medical disinfectants.
Health and Safety
While ethanol is widely used, it is important to note that it can be harmful if ingested in large quantities. Acute intoxication can lead to symptoms such as impaired coordination, blurred vision, and even unconsciousness or death in severe cases. Long-term consumption is associated with various health risks, including liver disease and an increased risk of certain cancers.
In summary, ethanol (CAS64-17-5) is a versatile compound with significant industrial and recreational uses, but it must be handled with care due to its potential health risks.
