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.

“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
“One does not realize the historical sensation as a re-experiencing, but as an understanding that is closely related to the understanding of music, or rather of the world by means of music.”
