Phase equilibria and volumetric properties of mixtures of highly fluorinated alcohols and water
Year: 2024
Type: article
Abstract: New thermodynamic data are reported for aqueous solutions of highly fluorinated alcohols of different chain lengths. The liquid-liquid equilibrium (LLE) T-x diagram of the binary mixture (1H,1H-perfluoropropanol + water) was determined, as well as the LLE phase diagram of the ternary mixture (1H,1H-perfluoropropanol + 1-propanol + water) at 298.15 K and atmospheric pressure. The mutual solubilities of water with several linear perfluorinated alcohols (CF 3 (CF 2 ) n CH 2 OH, n = 1–5) and the tertiary alcohol perfluoro- t -butanol ((CF 3 ) 3 COH) were also measured at 298.15 K. Finally, volumetric properties such as the excess molar volumes and partial molal volumes at infinite dilution of the different fluorinated alcohols in water were also determined and discussed comparing with equivalent data from the literature for the corresponding hydrogenated alcohols.
