Method/Apparatus/Procedure:
A static method with 500 cm stainless steel vessel equipped with a plunger, perforated-cup stirrer was used. The perforated cup was attached to a soft iron rod which was raised up by means of an electromagnet, and dropped downward under its own weight. Ethylene was displaced from a reservoir by mercury using a volumetric piston pump to the desired pressure. After equilibration, samples of gas and liquid were withdrawn for analysis. During the sampling process, an equivalent volume of mercury was allowed to flow from the sample bomb back to the equilibration vessel. The liquid portion of the samples was condensed at atmospheric pressure using dry-ice and acetone whereas the gas portion was aspirated volumetrically over water. Analysis was by gas chromatography.
