Solubility System: Ethene with 2-Methylcyclohexanone

Components:
   (1) 2-Methylcyclohexanone; C7H12O; [583-60-8]  NIST Chemistry WebBook for detail
   (2) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail

Original Measurements:
   Gallardo, M. A.; Carmen Lopez, M.; Urieta, J. S.; Gutierrez Losa, C., Can. J. Chem. 1989, 67, 809-811.

Variables:
   Temperature = 273.15 K to 303.15 K
   Pressure = 273.15 K to 303.15 K

Prepared By:
   W. Hayduk

Experimental Remarks:

   The authors fitted their data to the equation :
–ln x₁ = 8.3232 – 1190.24 (T/K)^–1
They also obtained ΔH/kJ mol^–1 = –9.9 and ΔS/JK^–1 mol^–1 = –69 for the transfer of one mole of ethene from the gas phase at 101.32 kPa to the hypothetical unit mole fraction solution.

Notes:
¹ The Bunsen and Ostwald coefficients were calculated by the compiler.

Method/Apparatus/Procedure:
The experimental apparatus and method is described elsewhere (Ref. 1). It consists of a system of burette, a mercury manometer and a solution vessel. The mole fraction of the dissolved gas is estimated from the volume change at constant pressure of saturated gas in the burettes, and the mass of the solvent in the solution vessel determined by weighing.

The vapor pressure of the solvent was measured and fitted to the following equation:
– ln (P₂/kPa) = – 5552.37 (T/K)^–1 + 18.046

Source and Purity of Materials:
   1. Ethene. Sociedad Español del Oxigeno. Specified purity 99.9%.
   2 2-Methylcyclohexanone. Merck. Purity checked by GLC to be ≥ 98.1%.

Estimated Errors:
   Solubility: δ x₁/x₁ = ± 0.007 (authors)
   Temperature: δT/K = ± 0.2
