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:

**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 (p_{2}/kPa) = –4591.3/ (*T*K) + 16.98.
