ABSTRACT
The solubilities of four former-reported diglycolic acid esters were measured at high temperatures ranging from (343 to 363) K and pressures from (11.8 to 19.7) MPa in supercritical carbon dioxide. The measured solubility data were correlated using a semiempirical model. Consequently, the calculated results showed satisfactory agreement with the experimental data and differed from the measured values by between (0.49 and 28.74) %.
