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.
