2,2'-Oxybis(N,N-bis(2-methoxyethyl)acetamide) was synthesized and confirmed by IR, NMR, and elemental analysis. The solubility of this compound was measured at temperatures ranging from (313 to 333) K and pressures from (9.2 to 15.2) MPa in supercritical carbon dioxide. The synthesized compound showed high solubility in supercritical CO(2) at easily accessible temperatures and pressures (e.g., 1.84 x 10(-3) mol.L(-1) at 9.2 MPa and 313 K). To confirm the tested solubility, the density-based correlations proposed by Bartle and Chrastil were investigated for the synthesized compound. The results showed good self-consistency of the data calculated using the Bartle semiempirical equation, which differed from the measured values by between (0.96 and 41.22) %. Better agreement with the experimental solubility data was obtained with the Chrastil model, for which average absolute relative deviations of less than 6 % were observed. The solubility data were also used to estimate the partial molar volume (V) over bar (2) for the compound in the supercritical phase using the theory developed by Kumar and Johnston.
