t/°CHenry's law constant [m**3 atm mol**-1]102 * Mass Fraction w1 (compiler) 104 * Mole Fraction x1 (compiler)
24.851.50 x 10-20.50469.410
 Method/Apparatus/Procedure:
   The original method and apparatus for the determination of Henry's law constants are described elsewhere.1 The general procedure was to add an excess quantity of 1,1-dichloroethene to distilled deionized water, place the sample in a  thermostat bath, and provide overnight mixing. A portion of this solution was returned to the stripping vessel. The 1,1-dichloroethene was stripped isothermally from the solution at a know gas flow rate. The Henry's law constant was calculated from the log of the concentration versus time plot. The experimental data values are averages of two or more replicates.

 Source and Purity of Materials:

   (2) Distilled and deionized.

 Estimated Errors:
   Solubility: ± 6 % std. dev.
   Temperature: ± 0.05 K.
