Solubility System: Ethene with 1, 2-Dichloroethane

Components:
   (1) 1, 2-Dichloroethane; C2H4Cl2; [107-06-2]  NIST Chemistry WebBook for detail
   (2) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail

Original Measurements:
   Hannaert, H.; Haccuria, M.; Mathieu, M.P., Ind. Chim. Belge 1967, 32, 156-164.

Variables:
   Temperature = 273.15 K to 313.15 K
   Pressure = 273.15 K to 313.15 K

Prepared By:
   W. Hayduk, H.L.Clever

Experimental Remarks:

   The authors definitions are:

ΔH = 1,520 cal mol^–1, Enthalpy of dissolution
K = y₁/x₁ = mole fraction gas in gas phase ÷ mole fraction gas in liquid phase

π / atm = total pressure

ν = coefficient of fugacity

The function Kπν /atm, is equivalent to a Henry's constant in the form H_1,2/atm = (ƒ₁/atm)/x₁ where ƒ₁ is the fugacity.

Notes:
   ¹  Mole fraction solubility calculated by compiler for a gas partial pressure of 101.3 kPa using the equation developed by the authors with v = 1, for the applicable temperature range: log ( Kπν) = 3.166 – ( ΔH/cal mol^–1 )/(2.3R(T/K))

Method/Apparatus/Procedure:
   The authors described several methods used; the one used in this case was considered the most accurate.
The apparatus was of glass and consisted of a burette in which the gas was confined over mercury, an absorption vessel agitated electromagnetically, a turbine for circulating the gas, a mercury manometer and a constant temperature bath. The exposed tubing was minimized. The quantity of gas introduced into the absorption vessel was measured volumetrically.

Source and Purity of Materials:
   1. Ethene. Air Liquide. Specified purity 99.9%.
   2. 1,2-Dichloroethane. Produced by synthesis. Distilled and fractionally crystallized. Density at 20 °C is 1.2627 g cm^–3. Purity > 99.9% by spectroscopy and gas chromatography.

Estimated Errors:
   Solubility: δ x₁/x₁ = ± 2 to 5%
   Temperature: δT/K = ± 0.2
   Pressure: p/mm Hg = ± 0.1 (author)
