Definition of Trifluoroacetic Anhydride:
Trifluoroacetic anhydride (TFAA) is the acid anhydride of trifluoroacetic acid, an organic compound with the molecular formula C4F6O3.
The colorless volatile liquid in general state, hygroscopic, decomposed in water and ethanol, soluble in ether and acetic acid. It is a representative strong dehydrating agent with broad chemical reactivity.
It has a wide range of chemical reactivity. It is mainly used as an analytical reagent, solvent, catalyst, dehydration condensation agent, carboxyl, and amino trifluoroacetylation protective agent to synthesize various polymers and fine chemicals.
In addition, it is also widely used in dyes, photosensitive materials, liquid crystal display materials, aerospace technology, pesticides, medicine, polymer materials, etc.
