Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The vapour pressure of the substance (XDI) at room temperature is 0.0206 Pa and the vapour pressure of the hydrolysis product (XDA) is calculated to be 1.95 Pa at 25 degrees Celsius.

Key value for chemical safety assessment

Vapour pressure:
0.021 Pa
at the temperature of:
20 °C

Additional information

The vapour pressure of the substance (XDI) is determined by the gas saturation method and the vapour pressure of the hydrolysis product (XDA) has been calculated with the QSAR Model MPBVP (version 1.43).
