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. In the latter reference, however, additional extreme (maximum) solubility values are reported at a very dilute alcohol mixtures (ethanol mole fraction around 0.05). Argentina The concentrations of the amine mixtures were 6 mass % diethanolamine (DEA) + 24 mass % 2-amino-2-methyl-1-propanol (AMP), 12 mass % DEA + 18 mass % AMP, and 18 mass % DEA + 12 mass % AMP. Chem. 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.

Carbon dioxide has a very low solubility in ethanol. 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. This means that you cannot reply to this topic. Fundamentals Henry’s law constants are calculated for each temperature and are compared between to one another. Phys. In addition, the solubility parameter of ethanol is 26.5 MPa 1/2 while that of CO 2 is 14.6 MPa 1/2 at 40 °C and 20 MPa. Solubilities of carbon dioxide in aqueous ethanol solutions, determined at 15, 20, 25, 30 and 35°C at atmospheric pressure, show a minimum at each temperature. 4, 841 (1975). 66, 25 (1978). However, its application has been retarded partially because of the limited solubility of commercial and environmentally friendly surfactants in supercritical CO 2. Correspondence to B. Ferguson,Can.

Solubilities of carbon dioxide in aqueous ethanol solutions, determined at 15, 20, 25, 30 and 35°C at atmospheric pressure, show a minimum at each temperature. 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.
