 Notes:
   1  Calculated by compiler; x1 is for a partial pressure of 101.325 kPa.

 Method/Apparatus/Procedure:
   Glass equilibrium cell fitted with a magnetic stirrer. Pressure measured with a Bourdon gauge. Samples of liquid analyzed by stripping out ethene. The solubilities were measured at several pressures below atmospheric and Henry's constant was determined. Details in Ref. 1.
