Uses of Ethanol - Solvent and Fuel
Ethanol is a versatile chemical that serves as a solvent for various substances and a clean, renewable fuel. Its dual uses are vital in chemistry and green energy.
Ethanol as a solvent
- Ethanol dissolves many substances, helping mix ingredients.
- It can dissolve oils, resins, and medicines.
- Chemists use ethanol as a solvent in laboratory experiments.
- Ethanol evaporates quickly, leaving no residue.
- People use ethanol-based hand sanitizers for cleaning.
Ethanol as a fuel
- Ethanol burns with a clean flame, making it a useful fuel.
- Since the 1900s, cars have used ethanol blends in petrol.
- Ethanol is renewable, made by fermenting sugars from plants.
- Using ethanol fuel reduces pollution compared to fossil fuels.
- Some countries use mostly ethanol fuel in vehicles to cut carbon.
Summary of ethanol uses
- Ethanol dissolves a range of substances as a solvent in labs and products.
- Ethanol burns cleanly and is a renewable fuel for vehicles.
- Ethanol's dual uses make it a vital chemical in organic chemistry applications.
