Trifluoroethanol and hexafluoroisopropanol are used as solvents in research. [4] Fluorotelomer alcohols are precursors to perfluorocarboxylic acids. Pirkle's alcohol is used a chiral shift reagent in nuclear magnetic resonance spectroscopy.
Pentafluorophenol is the organofluorine compound (specifically a fluoroalcohol) with the formula C 6 F 5 OH. This is the perfluorinated analogue of phenol . It is a white solid that melts just above room temperature, and smells of phenol.
The synthesis of fluorotelomer alcohols requires a varying number of tetrafluoroethylene monomers that form an oligomer with a pentafluoroethyl iodide telogen. The fluorinated iodide then undergoes an addition with ethylene to form an organoiodine compound with increased synthesis possibilities. [ 1 ]
2-Fluoroethanol was originally synthesized by treating 2-chloroethanol with potassium fluoride, in a simple Finkelstein reaction. [5] The product has a lower boiling point that the starting material and may be conveniently isolated by distillation.
They are components of fire-fighting foam. [1] Fluorosurfactants (PFAS) reduce surface tension by concentrating at the liquid-air interface due to the lipophobicity of polyfluorocarbons. Chlorofluorocarbons are also perfluorinated compounds, many of which were formerly used as refrigerants until they were implicated in ozone degradation.
Nonafluoro-tert-butyl alcohol (IUPAC name: 1,1,1,3,3,3-hexafluoro-2-(trifluoromethyl)propan-2-ol) is a fluoroalcohol. It is the perfluorinated analog of tert -butyl alcohol . Notably, as a consequence of its electron withdrawing fluorine substituents, it is very acidic for an alcohol, with a p K a value of 5.4, similar to that of a carboxylic acid.
Trifluoroethanol is produced industrially by hydrogenation or the hydride reduction of derivatives of trifluoroacetic acid, such as the esters or acyl chloride. [1]TFE can also be prepared by hydrogenolysis of compounds of generic formula CF 3 −CHOH−OR (where R is hydrogen or an alkyl group containing from one to eight carbon atoms), in the presence of a palladium containing catalyst ...
[2] [3] It is highly electrophilic and fluoral forms a hydrate CF 3 CH(OH) 2 upon contact with water like other halogenated acetaldehydes. [4] It is commonly used in form of ethyl hemiacetal (1-ethoxy-2,2,2-trifluoroethanol, CF 3 CH(OCH 2 CH 3 )(OH) ) due to the aldehyde's high reactivity, including the tendency to polymerise.
