Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
The vapour pressure of the substance (TMPeoTA) was initially determined in accordance with the test method OECD Guideline 104 "OECD Guideline (similar to the test method AA. "Vapour Pressure according to the Dynamic Method"). The substance (TMPeoTA) has a vapour pressure of s 3.2x10-3 Pa (3.2x10-5 mbar) at 20°C according to the definition in the OECD Guideline 104 (Grain-Watson estimation).
in 2021 determination of the vapour pressure was re-done using effusion method. The substance (TMPeoTA) showed vapour pressure of s 4,41x10-7 hPa at 25°C according in a Knudsen cell method.
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.
