   ²  Stated by authors to be lim _x₁-->o(p₁/x₁ for p₁ = partial pressure of gas.

Method/Apparatus/Procedure:
   The solubilities were measured using a stirred reactor with a magnetic drive having a volume of 250 cm³ and equipped with a pressure gauge and a surrounding jacket for temperature control. Gas and sample handling systems were attached. A volume of 100-200 cm³ of deaerated solvent was charged to the reactor and equilibrated. A small liquid sample chamber was used to confine a known volume of saturated solution. The sample was then completely evaporated into a much larger vessel. Helium carrier gas was used to increase the pressure of the vapor gas mixture to about 0.12 MPs. The sample was then analyzed by gas chromatography. Details are in Ref. 1.

Source and Purity of Materials:
   No information about gas or solvent source or purity was supplied.

Estimated Errors:
   Solubility: δC₁ = ± 3% (Complier)
