Solubilities of Diglycolic Acid Esters in Supercritical.

A series of new CO2-soluble diglycolic acid esters were designed and 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 (8.5 to 19.3) MPa in supercritical carbon dioxide.

Not only was the yield surprisingly found to be lower (item 4 in Table 1) in the HEBM reaction as compared to the hydrate case (item 3 in Table 1), but the noticeable amount of the diglycolic acid by-product highlighted the existence of higher-than-expected hydrolysis and the concurrent substitution of the formed glycolic acid. The DS of the product was in a similar range as found previously.

Diglycolic acid is a toxic metabolite of diethylene glycol (DEG) responsible for DEG-induced proximal tubular necrosis. Application Diglycolic acid was used in the preparation of needle-like aragonite particles from calcium nitrate aqueous solutions.

Thiodiglycolic acid's production and use as detection agent for copper, lead, mercury, and silver may result in its release to the environment through various waste streams. In soil experiments, thiodiglycolic acid was shown to be a biodegradation product of thiodiglycol which is a hydrolysis product of bis(2-chloroethyl) sulfide (mustard gas.
