Sodium trifluoroacetate Usage And Synthesis
Chemical PropertiesWhite crystalline powder
UsesSodium trifluoroacetate is used in acid catalyzed reactions. It is also used as an intermediate for active pharmaceutical ingredients (API). Further, it acts as a precursor for the trifluoromethylation of aldehydes using copper(I) halide as a catalyst.
Purification MethodsA possible contaminant is NaCl. The solid is treated with CF3CO2H and evaporated twice. Its solubility in CF3CO2H is 13.1% at 29.8o. The residue is crystallised from dilute EtOH, and the solid is dried in vacuum at 100o. [Hara & Cady J Am Chem Soc 76 4285 1954.] It can be precipitated from EtOH by adding dioxane, then recrystallising several times from hot absolute EtOH. Dry it at 120-130o/1mm. [Beilstein 2 IV 461.]
