Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The vapour pressure of the substance TMT anhydrous was calculated by QSAR (MPBPWIN Program, Modified Grain Method).

The vapour pressure of the the substance TMT 15 was determined by the dynamic method. The result (21.8 hPa at 20°C) is roughly the vapour pressure of water (at 20°C, Lide 2006) which is in consistence with the low concentration (15%) of the substance in aqueous solution.
