用途トリフルオロアセチル基を導入する合成試薬として用いられる。特に対応する酸塩化物である塩化トリフルオロアセチルが気体であり取り扱いが困難であるため、本試薬の使用頻度は高い。 スワーン酸化において、ジメチルスルホキシドの活性化剤として用いられる。 また、トリフルオロ酢酸の乾燥剤として用いることができる。
使用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.
製造方法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.
純化方法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.
