Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

MPBPVP v 1.43 predicted that test item has vapour pressure of 1.15 Pa (0.00865 mm Hg) at the temperature of 25ºC (Modified and Grain method).

Conclusions:
The estimated vapour pressure is 1.15 Pa (0.00865 mm Hg) at the temperature of 25ºC (MPBPVP v 1.43 Modified and Grain method).
Executive summary:

The estimated vapour pressure is 1.15 Pa (0.00865 mm Hg) at the temperature of 25ºC (MPBPVP v 1.43 Modified and Grain method).
