General description

三乙二醇二甲醚，又名三甘醇二甲醚，是一种乙二醇醚，常在电子、医药、涂料等领域中用作溶剂。三乙二醇二甲醚因缺乏活性官能团而具有化学惰性，十分适合化学合成使用。它具有强溶剂化能力，且呈现优异的热稳定性和化学稳定性，适于作为极其重要的溶剂、生产加工助剂和工业化学品配方。

Application

三乙二醇二甲醚用作：
  • 超临界抗溶剂-高压溶剂清洗 (Supercritical Anti-Solvent with High-Pressure Solvent Wash)改良系统中的萃取溶剂。
  • 钝化铁纳米粒子合成中的溶剂。

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). Using these ligands

Triethylene glycol and two of its derivatives were evaluated for reproductive toxicity in a continuous breeding protocol with Swiss CD-1 mice. Triethylene glycol (TEG: 0, 0.3, 1.5, and 3%), triethylene glycol diacetate (TGD: 0, 0.75, 1.5, and 3%), and triethylene

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
