Our lab bought HFIP (1,1,1,3,3,3, Hexafluro-2- propanol) for the objective of making PGA solutions, but it came in a powder presentation, so I was wondering if I can make a solution out of it to reach my objective.
Thanks.
hexafluoroisopropanol melts at -3 degrees Celsius, your substance is probably not hexafluoroisopropanol if it is solid at room temperature
Dear Carlos Miguel López Mendoza many thanks for sharing this very interesting technical question with the RG community. We frequently worked with hexafluoro-2-propanol (HFIP) in the past. At room temperature, it forms a mobile liquid with a pungent odor. When your sample is a solid at room temperature, it is clearly not HFIP. Technically, HFIP is manufactured by hydrogenation (addition of H2) of hexafluoroacetone. Hexafluoroacetone in its anhydrous form is a gas at room temperature. However, it forms different hydrates which are either liquid or solid at room temperature. Thus chances are that you might have a hexafluoroacetone hydrate at hand. What you can try is add some concentrated sulfuric acid to your sample and distil the mixture under normal pressure. If you are lucky, this could provide pure HFIP. Also please check your sample by NMR (1H, 13C, and 19F) and compare the spectra with the literature values.
Good luck with your work and best wishes, Frank Edelmann
