Structure of DEG and Related Polyols
Diethylene glycol is one of several glycols derived from ethylene oxide. Glycols related to and coproduced with diethylene glycol and have the formula HOCH2CH2(OCH2CH2)nOH are:
- n = 0 ethylene glycol ("antifreeze"); monoethylene glycol MEG
- n = 1 DEG
- n = 2 triethylene glycol, TEG, or triglycol
- n = 3 tetraethylene glycol
- n = 4 pentaethylene glycol
- n > 4 polyethylene glycol
These compounds are all hydrophilic, more so than most diols, by virtue of the ether functionality.

Famous quotes containing the words structure and/or related:
“One theme links together these new proposals for family policy—the idea that the family is exceedingly durable. Changes in structure and function and individual roles are not to be confused with the collapse of the family. Families remain more important in the lives of children than other institutions. Family ties are stronger and more vital than many of us imagine in the perennial atmosphere of crisis surrounding the subject.”
—Joseph Featherstone (20th century)
“A parent who from his own childhood experience is convinced of the value of fairy tales will have no difficulty in answering his child’s questions; but an adult who thinks these tales are only a bunch of lies had better not try telling them; he won’t be able to related them in a way which would enrich the child’s life.”
—Bruno Bettelheim (20th century)
