| | Trifluoroacetic Acid Anhydride Usage And Synthesis |
| Chemical Properties | Clear, colorless liquid | | Uses | Trifluoroacetic anhydride is used for the introduction of trifluoroacetyl group in organic synthesis. It is involved in the preparation of N- and O-trifluoroacetyl derivatives of a wide range of biologically active compounds for gas chromatography analysis. It plays an important role as desiccant for trifluoroacetic acid. It is also used in the oxidation of aldehydes to acids, esters, amides as well as in the protection of alcohols and amines. In addition, it is used as analytical reagents, solvents and dehydration condensing agent. It serves as an intermediate of fluorine fine chemicals, pharmaceuticals and agrochemicals. | | Uses | Used as analytical reagents, solvents, catalysts, dehydration condensing agent, protection agent of trifluoroacetylation of carboxyl and amino; used as Intermediate of fluorine fine chemicals, pharmaceutical, agrochemical. | | Safety Profile | A severe skin and eye irritant.Explosive reaction with dimethyl sulfoxide; nitric acid +1,3,5-triazine (at 36°C); nitric acid + 1,3,5-triacetylhexahydro-1,3,5-triazine (at 30°C). Incompatiblewith lithium tetrahydroaluminate. When heated todecomposit | | Purification Methods | Purification by distilling over KMnO4, as for the acid above, is EXTREMELY DANGEROUS due to the possiblility of EXPLOSION. It is best purified by distilling from P2O5 slowly, and collecting the fraction boiling at 39.5o. Store it in a dry atmosphere. Highly TOXIC vapour and attacks skin, work in an efficient fume hood.
