Ethyl tetrahydrofurfuryl ether

Details:

Ethyltetrahydrofurfurylether (ETE) Technical Data Sheet (TDS) Appearance: A colorless clear liquid. Other name: 2-(ethoxymethyl)tetrahydrofuran Characteristic: Ethyltetrahydrofurfurylether (ETE) is a strong aprotic solvent. It has a limited solubility in water. ETE can affect organolithium structures and reactivities through its bidentate structure. ETE is a flammable liquid. It should be protected from oxygen such as peroxides. Applications: Ethyltetrahydrofurfurylether (ETE) is used in coatings, paint strippers, and cleaning formulations. ETE is used as a modifier for the organolithium catalyst in anionic polymerization of dienes (butadienes, isoprene), styrene-diene copolmers, hydrogenated stryrene-butadiene block copolymers, and liquid polybutadienes, to increase the level of vinyl structure in the polyene.
