The equilibrium solubilities of two dodecylpolyoxyethylene polyoxypropylene ether nonionic surfactants (A(EO)BmB(PO)(n)) in supercritical carbon dioxide were measured at temperatures ranging from (308 to 328) K and pressures from (13.6 to 32.0) MPa in a stainless steel variable-volume view cell. The experimental data were correlated using a semiempirical model. The calculated results show satisfactory agreement with the experimental data.
