   The original method and apparatus for the determination of Henry's law constants, as described by Mackay, et al.,1 was used. The general procedure was to add an excess quantity of 1,1,1-trichloroethane to distilled deionized water,  place the sample in a thermostat bath, and mix overnight. A portion of this solution was returned to the stripping vessel. The 1,1,1-trichloroethane was stripped isothermally from the solution mixture at a known gas flow rate. The Henry's law constant wa 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:
   (1) Purest quality available, used without further purification, stated purity greater than 99 %.
   (2) Distilled and deionized.

Estimated Errors:
   Solubility: ± 6.0 % std. dev.
   Temperature: ±0.05 K.
