Abstract

A series of diglycolic acid esters, potent CO2-philic chelating agents, were designed and synthesized. The solubilities of these compounds in supercritical CO2 were determined at temperatures from (313 to 333) K and pressures from (8.6 to 20.4) MPa. All of the synthesized esters showed good to high solubility (as high as 1.6· 10− 2 mol· L− 1 for compound 1 at 9.3 MPa and 313 K) in supercritical CO2 at easily accessible temperatures ...
