Experimental Data:   (Notes on the Nomenclature)
t/°CHenry's law constant [m**3 atm mol**-1]102 * Mass Fraction w1 (compiler) 104 * Mole Fraction x1 (compiler)
24.855.83 x 10-20.19692.586
   The original method and apparatus for the determination of Henry's law constants are described in Mackay et al. (ref. 1). The general procedure was to add an excess of the organic compound to distilled deionized water and stir the mixture overnight. A portion of this  solution was returned to a stripping vessel. The solute was stripped isothermally from the solution at a known gas flow rate. The Henry's law constant was calculated from a log of the concentration versus time plot. The experimental data points are average of two or  more replicates.

Source and Purity of Materials:
   (1) Purest quality available and used without further purification; stated purity >99 %.
   (2) Distilled deionized.

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