Abstract

A series of sodium bis (2-ethylhexyl) sulfosuccinate (AOT) analogue surfactants [sodium dibutyl sulfosuccinate (DBSS), sodium dipentyl sulfosuccinate (DPSS), sodium dihexyl sulfosuccinate (DHSS), and sodium dioctyl sulfosuccinate (DOSS)] were synthesized and characterized with 1H NMR and elemental analysis. The solubilities of surfactants in supercritical CO2 (scCO2) and supercritical 1, 1, 1, 2-tetrafluoroethane (HFC-134a) fluids ...
