Method/Apparatus/Procedure:
Ethene is bubbled through a presaturator and then through the equilibrium cell, both being filled with the molten solvent. The cell is thermostated in a nitrogen bath. After saturation, a (molten) liquid sample is withdrawn into an evacuated trap connected to a gas handling system. The solvent solidifies, and the volume of the gas released is measured in a burette over water at a known temperature and pressure. The mass of the solid solvent is determined. Further details are in Ref. 1.
Source and Purity of Materials:
1. Ethene was from Matheson Gas Products at a specified purity of 99.5%.
2. Hexatriacontane was from the Aldrich Chemical Company at a specified purity of 99.0%.
