Triethylene glycol is a transparent, colorless,
low-volatility, moderate-viscosity, watersoluble
liquid . Under normal conditions,
there is no detectable odor; under high vapor
concentrations, a slightly sweet odor may be
detected . It is completely miscible with water
and many organic liquids . Triethylene glycol
has properties similar to other glycols and
may be used preferentially in applications
requiring a higher boiling point, higher
molecular weight, or lower volatility than
diethylene glycol .
The hydroxyl groups on triethylene glycol
undergo the usual alcohol chemistry giving
a wide variety of possible derivatives .
Hydroxyls can be converted to aldehydes,
alkyl halides, amines, azides, carboxylic
acids, ethers, mercaptans, nitrate esters,
nitriles, nitrite esters, organic esters, peroxides,
phosphate esters and sulfate esters .
Triethylene glycol may be used directly as a
plasticizer or modified by esterification . The
solubility properties of triethylene glycol are
important for many applications . End-uses
for triethylene glycol are numerous . (See
Table 1 .)
