  • Toxicity Summary: IDENTIFICATION AND USE: Triethylamine (TEA) is a colorless liquid. It is used as catalytic solvent in chemical synthesis; accelerator activators for rubber; wetting, penetrating, and waterproofing agents of quaternary ammonium types; curing and hardening of polymers; corrosion inhibitor; propellant. HUMAN EXPOSURE AND TOXICITY: Aside from irritation of the eyes and respiratory tract, triethylamine also stimulates the central nervous system, because it inhibits monamine oxidase. Experimental studies were conducted in four healthy men on the metabolism of inhaled TEA (20 mg/cu m) with and without ethanol ingestion. Three subjects displayed visual disturbances in the experiments without ethanol. These same subjects did not experience any visual disturbances in those experiments containing ethanol. In another study, four hour exposure to a TEA concentration of 3.0 mg/cu m seemed to cause no effects, whereas exposure to 6.5 mg/cu m for the same period caused blurred vision and a decrease in contrast sensitivity. Two volunteers were exposed to various airborne concentrations of triethylamine. Levels of 18 mg/cu m for eight hours caused subjective visual disturbances (haze and halos) and Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: Measured BCF values of <0.5 and <4.9 were reported in carp (Cyprinus carpio; lipid content, 3.9%), exposed to triethylamine at 0.5 and 0.05 mg/L, respectively, over a 6-week period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 51(SRC), determined from a structure estimation method(2), indicates that triethylamine is expected to have high mobility in soil(SRC). The pKa of triethylamine is 10.78(3), indicating that this compound will exist almost entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the cation from moist soil is not expected because cations do not volatilize(SRC). Triethylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 57.07 mm Hg at 25 °C(3). A 28% of Theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation may be an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 51(SRC), determined from a structure estimation method(2), indicates that triethylamine is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected based upon a pKa of 10.78(3), indicating that triethylamine will exist almost entirely in the cation form and cations do not volatilize(SRC). Triethylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). According to a classification scheme(5), BCFs of <4.9(6), suggest bioconcentration in aquatic organisms is low. Triethylamine present at 100 mg/L, reached 28% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(6). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), triethylamine, which has a vapor pressure of 57.07 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase triethylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4.2 hours(SRC), calculated from its rate constant of 9.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Triethylamine does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
