Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Regarding stability in the environment experimental data are available in context of phototransformation in air as well as estimated data for phototransfomation in air and soil. The experiment was performed in large outdoor chambers under natural conditions of temperature, humidity, and illumination (Pitts et al., 1978). After 90 minutes of exposure to these chambers triethylamine did completely disappear. The dissipation half-life of the substance was calculated with the help of the computer tool SRC AOPv1.92 (BASF SE, 2008). The result is given as 4.16 hours, whereby the estimation does not intend to cover ionisable compounds. Atkinson (1987) calculated a half-life of 4.5 hours for triethylamine.
Triethylamine lacks functional groups that would hydrolyze under environmental conditions, therefore the substance is not expected to undergo hydrolysis in the environment.
Direct photolysis will not be significant regarding phototransformation in soil, due to the fact that triethylamine does not contain any chromophores which absorb radiation greater than 290 nm (Howard, 1990).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
