Abstract
| - Dilute water in carbon dioxide miniemulsions and macroemulsions are formed with a hydrocarbonsurfactant, sodium bis(3,5,5-trimethyl-l-hexyl)sulfosuccinate. The emulsion droplets do not appear toflocculate at 30−60 °C and 29 MPa indicating that solvation of the tails by CO2 is sufficient to screen theinterdroplet attractive interactions. The solvation of the tails is enhanced by the low cohesive energydensity methyl groups that interact more favorably with CO2 than methylene groups.
