etüülspiirit

Etüülspiirit, also known as ethanol or ethyl alcohol, is a volatile, colorless liquid with a distinctive odor. It is the primary alcohol found in alcoholic beverages and is produced through the fermentation of sugars by yeast. Industrially, it is often synthesized from ethylene through a hydration process.

Ethanol is a versatile chemical compound with numerous applications. It serves as a solvent in various industries, including pharmaceuticals, cosmetics, and cleaning products. Its ability to dissolve both polar and nonpolar substances makes it highly effective. In the medical field, ethanol is used as a disinfectant and antiseptic due to its antimicrobial properties.

As a fuel, ethanol is blended with gasoline to create biofuels, reducing reliance on fossil fuels and lowering emissions. Its combustion produces water and carbon dioxide. Ethanol's high octane rating also contributes to engine performance.

While widely consumed in beverages, excessive intake of ethanol can lead to intoxication, addiction, and various health problems. In industrial and fuel applications, it is denatured, meaning substances are added to make it unfit for human consumption and often to alter its tax status. The production and use of etüülspiirit are subject to regulations in many countries.
