Any TFE released into the environment is expected to partition almost
entirely to the atmosphere, where it will quickly react with atmospheric
hydoxyl radicals (°OH), with an average atmospheric lifetime of < 2
days. Subsequent decomposition yields carbonyl fluoride C(=O)F2
which is further hydrolysed in the presence of atmospheric water to form
hydrogen fluoride (HF) and CO2, the HF being washed out by
rain. Again, the atmospheric lifetime for C(=O)F2 is short,
being calculated in a global 3 -dimensional modelling study to be 3.9 to
Because of its short atmospheric lifetime, the direct impact of TFE on
the greenhouse effect is expected to be negligible. This has been
confirmed by a calculation of a global warming potential (GWP) of 0.021
(CO2 = 1) for an integration horizon of 100 years (Acerboni
et al 2001). Since TFE does not contain chlorine or bromine atoms it has
no effect on the stratospheric ozone layer. However, TFE may enhance the
formation of tropospheric ozone (O3) depending on the emitted
In the aquatic environment, no hydrolysis of TFE will occur. TFE is not
prone to rapid biodegradation and bioaccumulation. TFE will not absorb
significantly to soils and sediments (log Koc = 1.05).
Due to its high vapour pressure and Henry's law contant (92 109
Pa.m3/mol), TFE will volatilise to atmosphere from water, and wet and
dry soil surfaces.
