Method/Apparatus/Procedure:
   Experiments are described in Ref. 1. A steel vessel was used along with a heating block, thermostat and pressure gauge for measuring the P - T - x data. Approximate Henry's constants and ethene solubilities, corresponding to a gas partial pressure of 101.3 kPa were calculated by the compiler for pressures to 2.9 MPa at 50 °C, and 5.0 MPa at 100 °C and 150 °C.

Source and Purity of Materials:
   1. Ethene. Source and purity not specified.
   2. Bromochloromethane. Source and purity not specified. Densities and vapor pressures given in paper. Approximate equation for vapor pressures (compiler) based on data given:

log (P/atm) = 4.4726 – 1521.3/(T/K)

Estimated Errors:
   Solubility: δ x₁/x₁ = ± 2% (Compiler)
   Temperature: δT/K = ± 0.1 (authors)
