Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, and ethylene glycol. DEG is a widely used solvent.

 

Diethylene glycol, also known as 2,2'-oxybisethanol, is colorless, virtually odorless, viscous, hygroscopic liquid with a sweetish taste. It has a higher boiling point, viscosity and specific gravity compared to MEG. It is miscible with water, ethanol, ethylene glycol, chloroform, and furfural, but not miscible with carbon tetrachloride, carbon disulfide, straight-chain aliphatic hydrocarbons, or aromatic hydrocarbons. Diethylene glycol is an important industrial solvent. It is utilized in the manufacture of unsaturated polyesters, plasticizer and some important resins.

Diethylene glycol is one kind of glycols derived from oxirane. These glycols have the formula HOCH₂CH₂(OCH₂CH₂)_nOH are:
n = 0 ethylene glycol; MEG
n = 1 DEG
n = 2 triethylene glycol, TEG, or triglycol
n = 3 tetraethylene glycol
n = 4 pentaethylene glycol
n > 4 polyethylene glycol

Preparation: Diethylene glycol is produced as a by－product, along with triethylene glycol, in the manufacture of ethylene glycol from hydrolysis of ethylene oxide. The industry generally operates to maximize MEG production. Availability of DEG will depend on demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements.

 

Uses: Diethylene glycol is used to produce unsaturated polyester resins, plasticizers, polyurethanes, rubber, fiberglass, oil viscosity improver, and so on. It is also used as antifreeze, gas dehydration, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant and finishing agent, antidesiccant of paste and a variety of glue, etc. What's more, it is used as solvent for oil, resins, nitrocellulose, printing ink, dyes and other organic compounds. Although a dilute solution of diethylene glycol can also be used as a coolant, ethylene glycol is much more commonly used.
