t/°CHenry's law constant [(dimensionless)]102 * Mass Fraction w1 (compiler) 105 * Mole Fraction x1 (compiler)
103.69 x 10-12.030 x 10-22.206
205.816 x 10-12.203 x 10-22.394
309.544 x 10-12.201 x 10-22.392
 Method/Apparatus/Procedure:
   The multiple equilibrium technique with direct aqueous injection into a gas chromatograph was used to determine the dimensionless Henry's law constant. A known volume of liquid and gas was introduced into a syringe and allowed to equilibrate.  The ratio of gas to liquid volume was maintained constant. While vapor samples were injected directly into a gas chromatograph, the liquid samples were preconcentrated by liquid-liquid extraction before analysis. The experiments were carried out in duplicates.
