Description

General description

Diethylene glycol (DEG) is employed as a comonomer during the synthesis of poly (ethylene terephthalate) (PET). It undergoes oxidation on treatment with nitric acid. Its toxicity has been assessed. The ozonation and modified Fenton oxidation of DEG have been investigated.

Application

Diethylene glycol may be used in the preparation of bis(2,2′:6′,2″-terpyrid-4′-yl) diethylene glycol, which can act as a precursor for producing water-soluble coordination polymers.
