Beschreibung

Allgemeine Beschreibung

2,2,2-Trifluoroethanol (TFE) is a fluorinated compound used as a solvent in organic synthesis. Peptides and proteins are experimentally studied using TEE as a cosolvent. In TFE, hydrogen peroxide is effective for oxidizing sulfur compounds.

Anwendung

2,2,2-Trifluoroethanol is used as a solvent:

• In the preparation of nylon/Ag composite nanofibers by electrospinning method.
• To study the combination of two polymers PANI (polyaniline) and PHB (polyhydroxy-butyrate).

Leistungsmerkmale und Vorteile

2,2,2-Trifluoroethanol is more acidic than ethanol due to the presence of electronegative trifluoromethyl group.
