설명

일반 설명

Diethylene glycol (DEG) is employed as a comonomer during the synthesis of poly (ethylene terephthalate) (PET).[1] It undergoes oxidation on treatment with nitric acid.[2] Its toxicity has been assessed.[3] The ozonation and modified Fenton oxidation of DEG have been investigated.[4]

애플리케이션

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.[5]
