Trifluoroacetic acid - Wikipedia
Trifluoroacetic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Trifluoroacetic acid (TFA) is a synthetic organofluorine compound with the chemical formula CF 3 CO 2 H. It is a haloacetic acid, with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms.

Trifluoroacetic acid: Uses and recent applications in organic synthesis
2013年12月1日 · Introduction. Trifluoroacetic acid 1(TFA, d1.480) is the simplest perfluoroorganic acid available, characterized by its strong acidity (pKa0.23 at 25 °C in H2O), high dielectric constant (ɛ = 42.1 at 25 °C), miscibility with water and most organic solvents and relativity low boiling point (71.8 °C) [1(a–c)].

2017年12月1日 · Trifluoroacetate (TFA) describes the salt of trifluoroacetic acid. It is the perfluorinated analogue of acetate and thus the perfluorinated carboxylate with the shortest possible chain length. Compared to acetic acid, the acidity of the molecule is considerably increased by the substitution of the C -bound hydrogen atoms by fluorine ( Chambers ...
