   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 1,2-dichloropropane 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. 1,2-Dichloropropane 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:
   (1) Purest quality available, stated purity >99 %, used as received.
   (2) Distilled deionized.

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