Abstract
Official abstract text for this publication.
There is provided a highly branched hydrocarbon based surfactant for stabilizing a water/supercritical carbon dioxide microemulsion. A surfactant comprising: a sulfate compound of Formula (1): R 1 —OSO 3 M (1) (where R 1 is a C 6-30 hydrocarbon group having a branched chain; and M is a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a C 2-3 hydroxyalkyl group, or an aliphatic alkanolammonium) for stabilizing a water/supercritical carbon dioxide microemulsion.
