Methodology:
The authors describe several methods used; the one used in this case is the least accurate.
The apparatus is of glass and consists of a burette in which the gas is confined over mercury, two bulbs for the solvent, one above the other, a mercury manometer and a constant temperature bath. A measured volume of solvent is degassed in the top bulb at ambient temperature and charged to the absorption bulb in the bath. Gas is charged to the desired pressure. The quantity of gas added at constant pressure is measured. Agitation is manual.
Sample Information:
- Ethene. Air Liquide. For narcosis, 99.9%.
- 2-Propanone. Merck and Co. Vapor pressure, p /mm Hg = 11 at -30°C and 184 at 20°C as specified by authors.
Measurement Errors:
Mass concentration (m/v) (1): δx1/x1 = ±10 to 15% (authors)
System Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Acetone, $\ce{ C3H6O }$; [67-64-1] NIST WebBook
Experimental Data
The authors definitions are:
ΔH = 1,890 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 H1,2/atm = (ƒ1/atm)/x1 where ƒ1 is the fugacity.

(1) Mole fraction solubility calculated by compiler for a gas partial pressure of 101.3 kPa using the equation developed by the authors with ν = 1, for the applicable temperature range:
log ( Kπν ) = 3.28 - ( δH/cal mol-1 )/(2.3R(T/K))
