An Evaluation of the Solubility of Ethene in Aqueous Organic Nonelectrolyte Solutions

Seven papers report ethene solubility data in eleven aqueous organic nonelectrolyte solutions. Most of the data were collected at 298 K and 1 atm (101.3 kPa) partial pressure of ethene. Only one system has been studied by more than one laboratory. There is no reliable way to evaluate these data. They are classed as tentative until confirmed by further experimental work.

Ethene + Methanol [57-56-1] + Water
Ethene + Ethanol [64-17-1] + Water
Ethene + 1-Propanol [71-23-8] + Water

Yano, Kidaka, Miyamoto and Murakami³ measured the solubility of ethene in water, the pure alcohol and four mixtures of 0.2, 0.4, 0.6 and 0.8 mole fraction alcohol at 298.15 K by a volumetric method for each of the three systems. The solubility values in water and in the pure alcohols agree well with other data. The data sets are classed tentative.

Ethene + 2-Butanone [74-18-5] + Water

Yorizane, Masuoka, Ida and Ideda¹ measured the solubility of ethene in both phases of the two phase liquid formed by mixing 2-butanone, CH₃COCH₂CH₃ (methyl ethylketone), and water. The gas phase was stated to be greater than 99 percent ethene. Measurements are reported at five temperatures between 281 K and 298 K and at ethene pressures between 1.013 and 5.238 MPa (10 - 51.7 atm). Ethene hydrates were observed to form at temperatures < 284 K and pressures > 1.175 MPa. The data are classed as tentative.

Ethene + 2-Amino-ethanol [141-43-5] + Water

Sada and Kito⁴ report the solubility of ethene in 0 to 3.83 mol L^-1 H₂NCH₂CH₂OH at 288.15 K and 0 to 5.70 mol L^-1 organic component at 298.15 K. The 2-amino-ethanol has little effect on the solubility of ethene in water. The Bunsen coefficient increases about 10% as the organic component increases from 0 to 5.70 mol L^-1 at 298.15 K. The data are classed as tentative.

Ethene + 2,2'-Iminobis-ethanol [111-42-2] + Water

Sada, Kumazawa and Butt⁵ measured the solubility of ethene in 0 to 3.123 mol L^-1 (HOCH₂CH₂)₂NH at 298.15 K. The solubility (Bunsen coefficient) appears to go through a small maximum at 2.038 mol L^-1 amine, but the change is only a percent or two more than experimental error. The data are classed tentative.

Ethene + 2,2',2''~Nitrilotris-ethano1 [102-71-6] + Water

Sada et al.⁵ Measured the solubility of ethene in 0 to 2.624 mol L^-1 (HOCH₂CH₂)₃N at 298.15 K. There appears to be a small increase in solubility (Bunsen coefficient) as the amine concentration increases, but the increase is only about twice the estimated error of the measurement. The data are classed as tentative.

Ethene + 1-Amino-2-propanol [78-96-6] + Water

Sada et al.⁶ measured the solubility of ethene in 0 to 3.240 mol L^-1 CH₃CHOHCH₂NH₂ at 298.15 K. The solubility (Bunsen coefficient) may go through a small maximum as the amine concentration increases, but the change is only about twice the magnitude of the estimated error of the measurement. The data are classed as tentative.

Ethene + 1,2-Ethanediamine [107-15-3] + Water

Sada et al.⁵ measured the solubility of ethene in 0 to 3.683 mol L^-1 H₂NCH₂CH₂NH₂ at 298.15 K. The solubility (Bunsen coefficient) appears to go through a small but definite maximum as the amine concentration increases. The data are classed as tentative.

Ethene + 1,1'Iminobis-2-propanol [110-97-4] + Water

Sada et al.⁶ measured the solubility of ethene in 0 to 2.982 mol L^-1 (CH₂CHOHCH₂)₂NH at 298.15 K. The solubility (Bunsen coefficient) appears to go through a small maximum as the amine concentration increases. The data are classed as tentative.

Ethene + 1-Methyl-2-pyrrolidione [872-50-4] + Water

Shenderei and Ivanovskii² report ethene solubility at 273, 278, 288 and 293 K and 13.3 -101.3 kPa in mixed solvents of 0 to 0.557 mole fraction water. Wu, Zeck, Langhorst and Knapp⁷ report ethene solubility at 298.15 k and 1 bar in mixed solvent of 0.083 to 0.960 mole fraction water. Limited comparison can be made between the Henry's constants calculated by the compiler in atm/mol fraction for the two studies. The results are of similar magnitude, but the Wu et al.. Henry constants appears to be larger at 0.544-0.557 mole fraction water and smaller at 0.083-0.104 mole fraction water than expected from the trends shown by the Shenderei and Ivanovskii values. There is no way to say which data set is the more reliable, both data sets are classed as tentative.
