| Hazard Information | Back Directory | [Description]
Trifluoroacetic acid anhydride (TFAA), a perfluoroacylated acylation reagent, forms stable, volatile derivatives with alcohols, amines, and phenols. | [Chemical Properties]
Clear, colorless liquid | [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. | [Preparation]
Trifluoroacetic anhydride is prepared by reaction of trifluoroacetyl chloride with an alkali metal or alkaline-earth metal salt of trifluoroacetic acid at approximately 50° C. | [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.
