Application: Triethylene glycol dimethyl ether can be used as a:
• Extracting solvent in a modified SA-HPSW (Supercritical Anti-Solvent with High-Pressure Solvent Wash) system.
• Solvent in the synthesis of passivated iron nanoparticles.
General description: Triethyleneglycol dimethyl ether, also known as triglyme, is a member of the glycol ether family and is commonly used as a solvent in industries like electronics, pharmaceuticals, coatings, and more. Triglymes are chemically inert because they lack reactive functional groups, making them well-suited for chemical synthesis. They have strong solvating abilities and demonstrate excellent thermal and chemical stability, which makes them highly valuable as solvents and processing aids in the manufacturing and formulation of industrial chemicals.
