Diglycolic acid (DGCA) and zinc oxide were also supplied by Aldrich.
Zinc oxide is insoluble in solvents, such as benzene, ethanol and toluene, so that zinc dicarboxylate catalysts have been prepared via its slurried reactions with glutaric acid derivatives and diglycolic acid. As illustrated in Table 1, some of the zinc glutarate derivatives are synthesized in reasonably high yields (94%-98%): zinc glutarate (ZnO/GA).
And, the reactivity of GA is also suppressed significantly through the replacement of 3-carbon by the electron-donating ether group (that is, diglycolic acid).
