 Method/Apparatus/Procedure:
   The water-rich mixture was studied using gas-liquid chromatography in which a mixture of methane and 1,1-dichloroethane vapor passed through the sampling loop. The eluted 1,1-dichloroethane was determined with a flame ionization detector.  The organic-rich mixture was studied using an isopiestic method in which CaCl2 solution controlled the partial pressure of water. The water concentration of the sample was determined using a Karl Fischer titration apparatus.
