Method/Apparatus/Procedure:
   The equilibration occurred in a 2 liter flask rotating in a constant temperature water bath for 20 hours. The analysis of CCl₃F was carried out using a Hewlett-Packard ⁶³Ni electron capture detector mounted in a gas chromatograph. Peak areas were quantified by a HP 3388A integrator and compared to the detector response of a standard sample.

Source and Purity of Materials:
   (1) AIRCO, Inc., used as received.
   (2) Collected from Puget Sound, Washington with salinity of 35.0 x 10^-3.

Estimated Errors:
   Solubility: ± 2.0 %.
   Temperature: ± 0.5 K.
