 Experimental Data:   (Notes on the Nomenclature)
  
t/°CHenry's law constant [(dimensionless)]102 * Mass Fraction w1 (compiler) 105 * Mole Fraction x1 (compiler)
206.73 x 10-11.91 x 10-22.072
 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.
