Notes:
   Table 1  ^*  The water-rich phase contained traces of tetrachloroethene.

Method/Apparatus/Procedure:
   The analytical method was used. Mixtures of (1), (2) and (3) were stirred at a given temperature for a time interval sufficient to achieve equilibrium between liquid phases. After this, the samples of the separate phases were selected for chromatographic analysis. Injections were made with a syringe kept at the corresponding temperature.
