202.3 x 10-51.0 x 10-34.15
 Method/Apparatus/Procedure:
   The colloid chemical method was used for observing the shift in the critical micelle concentration formation for a surfactant in aqueous solutions under the influence of halogenated hydrocarbons. The solubility was  calculated from the increment of standard chemical potential for the transfer of a fluoromethylene group from water into the fluorocarbon phase on the basis of experimental determination of the surface  activity of a perfluoroorganic surface active nonelectrolyte.
