Experimental Data:   (Notes on the Nomenclature)
t/°CHenry's law constant [m**3 atm mol**-1]102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)
24.857.83 x 10-41.4231.538
   The original method and apparatus for the determination of Henry's law constants, described by Mackay et al. (ref. 1), were used. The general procedure was to add an excess quantity of dibromochloromethane to distilled deionized water and mix the system  overnight. A portion of the solution was returned to the stripping vessel. Dibromochloromethane was stripped isothermally from the solution at a known 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, > 99 % pure, used as received.
   (2) Distilled and deionized.

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