   Critical Evaluation of Ethene Solubility in Propene and in Ten Alkanes from Propane (C3) to Hexatriacontane (C36), for pressures exceeding 0.2 MPa

There are surprisingly few data for solubility of ethene in alkane solvents at higher pressures and for some of these data it is not possible to accurately determine the gas partial pressures.

Ethene solubility in individual solvents are now discussed:

Propane; C₃H₈; [74-98-6]
Propene; C₃H₆; [115-07-1]

Elshayal and Lu¹ reported ethene solubility in propane for total pressures from 0.14 MPa to 3.92 MPa and for temperatures ranging from 199.8 K to 273.2 K. To check for consistency, the data were plotted as log x versus log p. Data for each isotherm were essentially linear over the whole range of partial pressures.

Although propene is not an alkane, the data for this solvent are included here because it is the only alkene for which data are available. The data of Rozhnov and Dorochinskaya² for 303.15 K and 323.15 K are reported only as Henry’s constants.

Both of the above data are classified as tentative.

2-Methylpropane (isobutane); C₄H₁₀ [75-28-5]

The most extensive solubility of ethene in 2-methyipropane solvent are those of Naumova and Tyvina³ which span a temperature range from 293.15 K to 393.15 K and a pressure range from 0.30 MPa to 6.08 MPa. For constant temperatures all the data are essentially linear on a log x versus log p graph. There is a minimum solubility at a temperature of approximately 360 K. This is consistent with data for other gases of low solubility. The results of Kozorozov and Lisin⁴ are consistent with those of Naumova and Tyvina at 333.15 K.

Both of the above data are classified as tentative.

The two solubility of Benedict et al.⁵ for 310.93 K and 455.26 K appear to be significantly lower than those from the other two sources for corresponding temperatures and pressures and are rejected.

Hexane; C₆H₁₄; [110-54-3]
Heptane; C₇H₁₆; [142-82-5]

Konobeev and Lyapin⁶ reported solubility for ethene in both hexane and n-heptane at temperatures from 293.15 K to 333.15 K and total pressures from 0.29 MPa to 3.2 MPa. However, the corresponding ethene partial pressures or gas phase compositions were not given. As expected, the solubility in hexane and heptane are very similar in magnitude for the same temperatures and pressures. These data are classified as tentative.

Paratella⁷ reported ethene solubility inn-heptane for high temperatures, from 373.15 K to 473 K, and high total pressures, from 4.05 MPa to 10.13 MPa. Whereas these data appear self-consistent, no other comparable results are available. The data of Paratella are classified as tentative.

Ethene solubility in n-heptane were reported by Shenderei and Ivanovskii⁸ for relatively low temperatures from 228.15 K to 248.15 K and for total pressures from 0.55 MPa to 1.66 MPa. Henry’s constants were also given which permitted extrapolation of these data to solubility corresponding to a pressure of 101.32 kPa. A comparison of the extrapolated Shenderei and Ivanovskii data with that obtained at low pressure (101.32 kPa) is very favorable, probably because both data were products of the same laboratory. These data are classified as tentative.

Octane; C₈H₁₈; [111-65-9I
Nonane; C₉H₂₀; [111-84-2]
Dodecane; C₁₂H₂₆; [112-40-3]

Data reported by Shenderei and Ivanovski⁸ for ethene solubility in n-octane are for the three temperatures 248.15 K, 238.15 K and 228.15 K and for pressures ranging from 0.25 MPa to 1.48 MPa. These low temperature data are entirely self-consistent.

Solubility for ethene in n-nonane as reported by Konobeev and Lyapin⁶ are for the temperatures 293.15 K, 313.15 K and 333.15 K and for total pressures ranging from 0.29 to 3.2 MPa. These data are entirely self-consistent.

The data for ethene solubility in n-dodecane reported by Ribeiro et al.¹⁰ are for relatively large temperature and pressure ranges, from 283.15 K to 348.15 K and from 0.51 MPa to 9.1 MPa. These data are also entirely self-consistent and are approximately consistent (within 8%) with the low pressure solubility in n-dodecane.

The above data for n-octane, n-nonane and n-dodecane are classified as tentative.

Eicosane; C₂₀H₄₂; [112-95-8]
Octacosane; C₂₈H₅₈; [630-02-4]
Hexatriacontane; C₃₆H₇₄; [630-06-8]

Only the work of Chou and Chao¹¹ is available for the three waxlike paraffinic solvents at the relatively high temperatures from 373 K to 573 K and total pressures from 0.51 MPa to 9.12 MPa. These data are consistent with those of lower molecular weight alkane solvents and are classified as tentative.
