Solubility System: Ethene with 1-Propanol

Components:
   (1) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail
   (2) 1-Propanol; C3H8O; [71-23-8]  NIST Chemistry WebBook for detail

Original Measurements:
   Yano, T.; Kidaka, T.; Miyamoto, H.; Murakami, T., Proc. Soc. Chem. Engrs, Japan (Osaka), Oct. 14, 1968, 89-90.

Variables:
   Temperature = 298.15 K
   Pressure = 298.15 K

Prepared By:
   W. Hayduk

Experimental Remarks:

   Although not specifically stated in paper it was assumed by the compiler that the reported solubility was for a total pressure of 101.325 kPa; therefore, the solubility for a partial pressure of 101.325 kPa was calculated assuming Henry's law and an ethene molar volume of 24320 cm³ / mole at 298.15 K and 101.325 kPa.

Notes:
   ¹  Calculated by compiler.

Method/Apparatus/Procedure:
   A glass apparatus was employed in which the uptake of gas by a known volume of solvent in a dissolution cell was volumetrically determined. The gas was displaced by mercury as the gas dissolved at constant pressure. A magnetically operated gas circulating pump and bubbling tip were provided for bubbling the gas through the solvent in the dissolution cell.
