Document Type and Number:
WIPO Patent Application WO/2011/108538
Kind Code:
A1
Abstract:
Disclosed is a hyperbranched hydrocarbon surfactant for stabilizing a water/supercritical carbon dioxide microemulsion.
Specifically disclosed is a surfactant for stabilizing a water/supercritical carbon dioxide microemulsion, which is composed of a sulfate ester compound represented by formula (1).
R1-OSO3M (1)
(In the formula, R1 represents a hydrocarbon group having a branched chain and 6-30 carbon atoms; and M represents a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a hydroxyalkyl group with 2 or 3 carbon atoms, or an aliphatic alkanol ammonium.)
