Method/Apparatus/Procedure:
Equilibrium was achieved by bubbling gas at constant temperature and pressure through benzene solvent stored in a stainless steel vessel. Gas and liquid phases were sampled and analyzed. The gas phase was condensed with liquid air then slowly warmed to room temperature. The residual liquid after evaporation of ethylene was considered to be benzene. The liquid phase was sampled at constant pressure by slowly displacing the mercury in a sample bomb and adding gas at a rate required to keep the pressure constant. The liquid sample was analyzed. Further details of analysis and calculations were not given in this paper, although some earlier work was mentioned but the reference to it was not given.
Source and Purity of Materials:
1. Ethene prepared by dehydration of ethanol and purified by distillation. Infra-red spectrum indicated no ether.
2. Benzene source and purity not specified.
