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.

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.

This work reports two new silver metalorganic precursors for the chemical vapor deposition of Ag metallic coatings. Both precursors are based on β-diketonate adducts, namely, Ag(hfac)(L) (H-hfac = 1,1,1,5,5,5-hexafluoro-2,4-pentanedione), where L is 1,10-phenanthroline (phen) or 2,5,8,11-tetraoxadodecane (triglyme).

Triethylene glycol dimethyl ether (triEGdiME) is structurally related to several compounds which produce reproductive and developmental toxicity, including teratogenicity in laboratory animals. In the present study, triEGdiME (0, 250, 500, or 1000 mg/kg/day) was administered by gavage to timed-pregnant CD-1
