Notes:
   ¹  This solubility is between a gas (ethene) phase, stated to be greater than 99% ethene and two separate, immiscible liquid phases with the compositions expressed as mole percent.
   ²  Calculated by compiler

Method/Apparatus/Procedure:
   The apparatus was described earlier¹. The equilibrium cell was a Jerguson gauge of stainless steel with glass windows having an internal volume of 90 ml. Equilibrium was achieved by means of a gas recirculation pump. Samples of each phase were analyzed by means of a Shimadzu GC equipped with a peak integrator and a Porapack Q column. The concentrations of water vapor in the ethene were so low that they could not be detected.

At low temperatures (less than 11 °C) and high pressures (greater than 11.6 atm) ethylene hydrates were observed to form.

Source and Purity of Materials:
   1. Ethene. Specified purity 99.95%.
   2. 2-Butanone. Specified purity 99.6%.
   3. Water. Distilled.
