Method/Apparatus/Procedure:
The method is similar to that described by Sage and Lacey. Accurately known masses of solvent and gas were charged into an evacuated equilibrium vessel. The temperature was controlled to ± 0.05 K. The volume occupied by the system in the equilibrium vessel was varied by forcing a definite amount of mercury into it from a graduated mercury supply vessel equipped with a movable electric indicator. Equilibrium was attained using an electromagnetic stirrer. The pressure was measured using pressure gauges. A sample of the gas phase was passed to a trap cooled to 213 K with acetone and dry ice. From a reading of a gas burette connected to the trap, the volume of ethylene was determined. From the increase in weight of the trap (0.5-1.5g) the solvent content of the gas phase was obtained.
