Ethylene Glycol Ethyl Ether CAS#110-80-5
2-Ethoxyethanol is a stable, colorless, flammable liquid that is synthetically produced worldwide. It belongs to the glycol ether family of solvents and is commercially known as Ethyl Cellosolve or Cellosolve, a trademark registered by Union Carbide in 1924.
2-Ethoxyethanol was originally developed to combine the chemical properties of both alcohols and ethers, providing hydrophilic and lipophilic characteristics while exhibiting lower volatility. This combination of properties helps improve production and processing characteristics.
Glycol ethers are produced by reacting anhydrous alcohols with ethylene oxide.
