It will cause an exothermic reaction with maleic anhydride at temperatures above
150°C. Triethylamine can react with oxidizing materials and, when heated to
decomposition, it emits toxic fumes of NOX. Triethylamine has the widest range of
...

Polyamic Acids and Polyimides: Synthesis, Transformations, ...
Alicyclic and aliphatic amines possess much higher basicity. For instance, the
pKa of triethylamine is 10.7. The next section discusses peculiar features of
polyamic acid catalytic cyclization kinetics using triethylamine as a highly basic
catalyst.

Handbook of Environmental Fate and Exposure Data For Organic ...
It also occurs naturally in some food and as a metabolic product. If released on
land, triethylamine should volatilize moderately from moist soil and should leach
into the soil. It has not been established whether it biodegrades in soil or water.

Thermodynamics: Fundamentals for Applications
Further, not only might changes of state shift a ternary among the classes shown
in Figure 9.25, but such changes may also cause more subtle shifts within a class
. As an example, consider mixtures of water, phenol, and triethylamine at 10°C ...

The photoreduction characteristics of fiuorenone are similar to those of p-
aminobenzophenone in that reduction occurs in triethylamine but not in isopropyl
alcohol or cyclohexane solutions.14 The efficiency of reduction by triethylamine
is ...

Industrial Chemical Exposure: Guidelines for Biological ...
Diethylamine and triethylamine have "skin" notations (ACGIH, 2000). The amines
are excreted in urine as such and after oxidation, which appears to be the major
route of biotransformation. The average rate of oxidation of dimethylamine was ...

Indirect Food Additives and Polymers: Migration and Toxicology
After oral administration, TEA is efficiently absorbed from the GI tract, rapidly
distributed, and partially metabolized into triethylamine-N-oxide.6 Formation of
diethylamine from TEA also occurs. More than 90% of the dose was recovered in
the ...
