The gas used in alcohol, specifically alcoholic beverages and also gasoline mixtures like gasohol, is ethanol (C2H5OH).
Ethanol, also commonly called ethyl alcohol or grain alcohol, is a volatile, flammable, colorless liquid with a slight characteristic odor. It's well-known for being the intoxicating ingredient found in beer, wine, and spirits. However, ethanol's uses extend beyond beverages.
Properties and Uses of Ethanol
- Beverages: Ethanol is the primary alcohol in alcoholic drinks, produced by the fermentation of sugars by yeasts.
- Solvent: It serves as a solvent in the manufacturing of various products, including medications, perfumes, and flavorings.
- Fuel Additive: Ethanol is added to gasoline to create gasohol, improving combustion and reducing emissions.
- Chemical Synthesis: It's an important building block for synthesizing other organic chemicals.
- Antiseptic: Ethanol has antiseptic properties and is found in hand sanitizers and medical wipes.
While other gases like carbon dioxide (CO2) are byproducts of alcohol fermentation, ethanol is the primary gas that is used in alcoholic beverages and fuel blends. The term "gas" may be slightly misleading as ethanol is a liquid at room temperature, but it readily vaporizes, making it a gaseous component in fuel mixtures.
