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 of, structure and/or related:
“I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.”
—Jimmy Carter (James Earl Carter, Jr.)
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
“So universal and widely related is any transcendent moral greatness, and so nearly identical with greatness everywhere and in every age,—as a pyramid contracts the nearer you approach its apex,—that, when I look over my commonplace-book of poetry, I find that the best of it is oftenest applicable, in part or wholly, to the case of Captain Brown.”
—Henry David Thoreau (1817–1862)
