Solubility of carbon dioxide in 2-methylbutyric, 2-methylvaleric and 2-methylhexanoic ester oils

Solubility measurements and correlation of carbon dioxide in pentaerythritol tetra-2-methylhexanoate. Comparison with other pentaerythritol esters

“…2, where the solubility data in terms of molar fraction are presented. The isotherm at 283.15 K was already measured and published [2]. The isotherms at 323.15 K and 343.15 K, i.e.…”

Solubility of Carbon Dioxide in Pentaerythritol Tetrabutyrate (PEC4) and Comparison with Other Linear Chained Pentaerythritol Tetraalkyl Esters

“…Unfortunately, in the literature there is a lack of such information, except for few systematic works, as [1][2][3][4][5][6][7]. For this reason, our group is involved in a research program to provide experimental measurements and the development of a general predictive model focused on the phase behavior of lubricant + refrigerant blends, with particular attention to systems of POE precursors and CO 2 [8][9][10][11][12][13][14].…”

Direct measurement of the heat of solution and solubility of carbon dioxide in 1-hexyl-3-methylimidazolium bis[trifluoromethylsulfonyl]amide and 1-octyl-3-methylimidazolium bis[trifluoromethylsulfonyl]amide

“…The gas solubility was also determined directly using a newly built experimental apparatus based on an isochoric saturation technique, similar to that used in our laboratory for high-precision, low-pressure gas solubility measurements (Jacquemin et al, 2006b) and to different high pressure cells described by other authors (Bobbo et al, 2007;Wahlström and Vamling, 1999;Fandiño et al, 2008). This experimental technique requires the precise knowledge of the vapor pressure of the liquid.…”
