Glass Ball as Bullet Solubility System: Dodecafluoropentane with Water
Components:
   (1) Dodecafluoropentane; C5F12; [678-26-2]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
Evaluator:
   A. L. Horvath, Imperial Chemical Industries Limited, Runcorn, U.K., July 1993.

 Critical Evaluation:
         The solubility of dodecafluoropentane (1) in water (2) has been studied by two work groups from the same laboratory; whereas, the solubility of water (2) in dodecafluoropentane (1) has not been investigated yet.

      The two sources of data, that of Kabal'nov et al.1 and that of Kabalnov et al.,2 are at the same temperature so a direct comparison of the measured values is possible. The two available data sets, measured at 298.15 K, are within 6 per cent of each other.

      Because it is not possible to say which of the two sets of measurements is more accurate, it is suggested that an average of the two is probably the most satisfactory. The average value provided in weight percent and mole fraction in Table 28 is considered tentative.

      It is apparent that the available measurements for this system can only be called sketchy, and that many more measurements are required to produce definitive solubility data.
