Eng. With the presence of ethanol, the solubility parameter, the dielectric constant and polarizability of CO 2 solvent (CO 2 /ethanol mixture) can be significantly improved. You can google Henry's law and CO2 solubitility for a more detailed approach using the chemical potentials for a binary water/ethanol mixture and carbon dixoide. Eng.

Tax calculation will be finalised during checkout. Postigo, M.A., Katz, M. Solubility and thermodynamics of carbon dioxide in aqueous ethanol solutions. Unlike in the case of ethanol, where enhancements in solubility where relatively independent on system conditions, solubility enhancements using triolein as co-solvent increased markedly with system pressure, being larger than using (1.2 to 1.6) % mol ethanol at about (24 to 28) MPa, depending on system temperature. The solubility of β-carotene in CO 2 modified with (1.2 to 1.6) % mol ethanol increased by a factor of 1.7 to 3.0 as compared to its solubility in pure CO 2 under equivalent conditions. Eng. Eng. 3, 347 (1964). 67, 1840 (1963) and69, 281 (1965). R. E. Gibbs and H. C. Van Ness,Ind.

In this work, the challenge of limited solubility of surfactant sodium bis (2-ethylhexyl) sulfosuccinate (AOT) in CO 2 is overcome by using ethanol as a co-solvent. A. Muccitelli and W. Yang Wen,J. In the latter reference, however, additional extreme (maximum) solubility values are reported at a very dilute alcohol mixtures (ethanol mole fraction around 0.05). 2 replies to this topic Share this topic: | More #1 boss429jc boss429jc.
