   (1) 1, 1'-[Methylenebis(oxy)]bis-ethane (formaldehyde diethyl acetal); C5H12O2; [462-95-3]  NIST Chemistry WebBook for detail
   (2) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail

Original Measurements:
   Lizano, L. P.; Lopez, M. C.; Royo, F. M.; Urieta, J. S., J. Soln. Chem. 1990, 19, 721-728.

   Temperature = 273.15 K to 303.15 K
   Pressure = 273.15 K to 303.15 K

Prepared By:
   C.L. Young

Experimental Remarks:

   The compiler calculated the Bunsen and Ostwald coefficients. Density data were calculated from the equation given in the source and ideal gas behavior was assumed.

The authors fitted the solubility data to the equation:
– ln x1 = –9.2184 + 1585.23/(T/K)

The enthalpy and entropy of solution at 298.15 K and a partial pressure of 101.32 kPa were:
ΔH = –13.18 kJ mol–1 and ΔS = –0.077 J K–1 mol–1.

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 solubility apparatus, based on the design of Ben-Naim and Baer, was described earlier (Ref. 1). The essential parts were a gas buret, mercury manometer, and solution vessel. The solvent was degassed in the solution vessel. The saturation and volumetric measurements were carried out using solvent saturated gas.

Source and Purity of Materials:
   (1) Sociedad Español del Oxigeno sample; purity 99.90 mole per cent.
   (2) Aldrich sample; purity better than 99 mole per cent.

Estimated Errors:
   Solubility: δ x/x = ± 0.002
   Temperature: δT/K = ± 0.05
