   (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.

   Temperature = 285.15 K to 303.15 K
   Pressure = 285.15 K to 303.15 K

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.

Experimental Data:   (Subscripts 1,2,3, ..., in column headings refer to components 1,2,3, ...)
T/KOstwald coefficient L [cm3 cm–3]α [cm3 (STP) cm–3 atm–1]Mole Fraction (x1)

   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
