Application:Trifluoroacetic acid is mainly used in the production of new pesticides, medicines and dyes, and also has great application and development potential in materials, solvents and other fields.Trifluoroacetic acid is mainly used to synthesize a variety of herbicides containing trifluoromethyl and heterocyclic rings. Currently, it can synthesize a variety of new herbicides with pyridyl and quinolyl groups; as an extremely strong protonic acid, it is widely used in Catalyst for alkylation, acylation, olefin polymerization and other reactions of aromatic compounds; as a solvent, trifluoroacetic acid is an excellent solvent for fluorination, nitration and halogenation reactions, especially the effect of its derivative trifluoroacetyl on hydroxyl and amino groups Chemicalbook has excellent protective effects and has a very important application in the synthesis of amino acids and peptide compounds. It is used to remove the tert-butoxycarbonyl (t-boc) protecting group of amino acids in peptide synthesis; trifluoroacetic acid is used as a raw material and modification for the preparation of ion membranes. agent, which can greatly improve the current efficiency of caustic soda industry and extend the service life of membranes; trifluoroacetic acid can also synthesize trifluoroethanol, trifluoroacetaldehyde and trifluoroacetic anhydride.Mercury trifluoroacetate causes fluorobenzene to undergo a mercury reaction (electrophilic substitution) at room temperature, and can also convert hydrazones into diazo compounds.The lead salt of this acid converts aromatics into phenols.
