The invention relates to a process for the production of trifluoroacetic acid. According to the invention, it comprises the hydrolysis step of 1,1,1-trichloro-2,2,2 -TRIFLUOROETHANE BY ITS REACTION WITH WATER IN THE PRESENCE OF A CATALYST WHICH COMPRISES A COMPOUND OF AN INORGANIC METAL. ...
with non-oxidizing nature makes it a widely used reagent in organic synthesis. Trifluoroacetic acid can use as an ion pairing agent in liquid chromatography, as a solvent in NMR spectroscopy and as a calibrant in mass spectrometry. It is used as a catalyst in esterification reaction and ...
Trifluoroacetic acid is transformed into N-alkyl- or N-aryltrifluoroacetimidoyl chlorides or bromides in good yields by reaction with alkyl- or arylamines in the presence of triphenylphosphine, triethylamine and carbon tetrachloride or carbon tetrabromide, respectively. No reaction takes place with Cl...

reaction. Accordingly, we envisioned that TiO2-based NPs could catalyse the photo-driven decarboxylative C–H trifluoromethylation reaction with trifluoroacetic acid as a trifluoromethyl source (Fig. 1c). More importantly, the similarity to the photocatalytic water splitting process also implies the ...
