Abstract
The liquid–vapor separation factors in dilute solutions of methane, ethane, propane, n-butane, and isobutane in germanium tetrafluoride have been determined experimentally at 295 K by statically balancing phases. The measured temperature-dependent saturated vapor pressure over liquid germanium tetrafluoride in the range 260–300 K can be represented by the Antoine equation: log P (atm) = 5.2–1200/T. We have calculated the enthalpies of vaporization and fusion of germanium tetrafluoride:ΔH v 0= 22.9 kJ/mol and ΔH m 0(GeF4) = 8.0 kJ/mol.
