Glass Ball as Bullet Solubility System: 1,1,1,2,2,3,3,4,5,5,5-Undecafluoro-4-(tri-fluoromethyl)-pentane with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) 1,1,1,2,2,3,3,4,5,5,5-Undecafluoro-4-(tri-fluoromethyl)-pentane; C6F14; [355-04-4]  NIST Chemistry WebBook for detail
Evaluator:

 Critical Evaluation:
         The solubility of 1,1,1,2,2,3,3,4,5,5,5-undecafluoro-4-(trifluoromethyl)-pentane (1) in water (2) has been studied by two work groups in the same laboratory; whereas, the solubility of water (2) in 1,1,1,2,2,3,3,4,5,5,5-undecafluoro-4-(trifluoromethyl)-pentane (1) has not been investigated yet.

      The two experimental determinations by Kabal'nov et al.1 and by Kabalnov et al.2 are in reasonable agreement, although further studies are required before any values can be recommended. Because it is not possible to say which of the two values is more accurate, it is suggested that the average of the two is probably the most reliable. The average value presented in Table 31 in weight percent and mole fraction is classified as tentative.
