Method/Apparatus/Procedure:
The apparatus consisted of a high pressure piston pump, Bourdon pressure gauges, a stainless steel capillary tube equilibrium cell 4.7 mm in inside diameter, a tubular storage chamber for the gas, as well as an associated temperature sensing element, sampling probes and valves. The apparatus was mounted in a constant temperature chamber. The equilibrium cell was charged with a known quantity of solvent by rotating it to a horizontal position. The quantity of gas was determined by material balance and the PV relation in the gas supply tube.
Source and Purity of Materials:
- Ethene purity was specified to be 99.99%.
- Water was double distilled.
Estimated Errors:
Ambient temperature: δT/K = ±0.5
Mass concentration (m/v) (1): δx1/x1 = ±0.05 or ±5% (Compiler)
Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
