   (1) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail
   (2) 1-Pentanol; C5H12O; [71-41-0]  NIST Chemistry WebBook for detail

Original Measurements:
   Boyer, F. L.; Bircher, L. J., J. Phys. Chem. 1960, 64, 1330 - 1331.

   Temperature = 298.15 K, 308.15 K
   Pressure = 298.15 K, 308.15 K

Prepared By:
   M.E.Derrick, H.L. Clever

Experimental Remarks:

   The Bunsen coefficient was calculated by the compiler.
The mole fraction solubility was taken from Boyer's thesis1.
See the methanol data sheet for the equations relating the mole fraction solubility and the number of normal alcohol carbon numbers.

   A commercial Van Slyke blood gas apparatus (E. H. Sargent Co.) was modified by the authors.

The total pressure of the gas and the solvent vapor in the solution chamber was adjusted to a pressure of one atm. The pressure was maintained at one atm during the solution process. The saturated solution was transferred to a bulb below the lower stopcock of the extraction vessel and sealed off. The gas and solvent vapor were then brought to volume over mercury. See (2) for details of the extraction procedure.

Source and Purity of Materials:
   (1) Ethene. Matheson Co. Stated to be 99.5 mol per cent.
   (2) 1-Pentanol. Source not given. Treated by standard methods to remove aldehydes and ketones, then dried and distilled.

Estimated Errors:
   Solubility: δL/cm3 = ± 0.03 (at 298.15 K); ± 0.01 (at 308.15 K)
   Temperature: δT/K = ± 0.01
