Glass Ball as Bullet Solubility System: Ethene with 1, 4-Dioxane
Components:
   (1) 1, 4-Dioxane; C4H8O2; [123-91-1]  NIST Chemistry WebBook for detail
   (2) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail
Original Measurements:
   Gallardo, M. A.; Urieta, J. S.; Gutierrez Losa, C., J. Chim Phys. Phys.-Chim. Biol. 1983, 80, 621-25.

 Variables:
   Temperature = 285.15 K to 303.15 K
   Pressure = 285.15 K to 303.15 K

 Prepared By:
   H.L. Clever

 Experimental Remarks:
   The compiler calculated Bunsen and Ostwald coefficients from the author's mole fraction values assuming ideal gas behavior. The values are rounded to the nearest 0.005.
The authors fitted their data to the equation:
– ln x1 = 3.648 ln (T/K) – 16.123 from which they obtained
ΔH°1/kJ mol–1 = –9.04, and ΔS°1/J K–1 mol–1 = –69 for the transfer of one mole of ethene form the gas phase at 101 kPa to the hypothetical unit mole fraction solution.

 Notes:

Method/Apparatus/Procedure:
   The apparatus is similar to that of by Ben-Naim and Baer (Ref. 1). It was described in detail in an earlier paper (Ref. 2).

The apparatus consists of a gas buret, mercury manometer, and solution vessel. The solvent is degassed in the solution vessel. Measurements were carried out on the solvent vapor saturated gas.

Literature 1,4-dioxane vapor pressure data were fitted to the equation

ln (p2/kPa) = –4591.3/ (TK) + 16.98.

Source and Purity of Materials:
   (1) Ethene. Sociedad Espanol del Oxigeno. Stated to be 99.90%.
   (2) 1, 4-Dioxane. Merck and Co. Purity checked by GLC to be ≥ 99 %.

 Estimated Errors:
   Solubility: δ x1/x1 = ± 0.01
   Temperature: δT/K = ± 0.1
   Pressure: δp1/kPa = ± 1
