2,2′-Oxybis(N,N-diethylacetamide), 2,2′-oxybis(N,N-dibutylacetamide), and 2,2′-oxybis(N,N-dihexylacetamide) were synthesized, and their structures were confirmed by IR, NMR, and elemental analysis. The solubilities of compounds were measured at temperatures ranging from (313 to 333) K and pressures from (8.7 to 16.4) MPa in supercritical carbon dioxide. The measured solubilities were correlated using a semiempirical model. The calculated results showed satisfactory agreement with the experimental data and differed from the measured values by between (4.54 and 30.84) %.
