Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Main sequence

A total of ten runs were completed for the main sequence. Equilibrium with regard to vapour pressure was assessed to have been reached over the final five runs. Thus the final five runs have been used to calculate the definitive vapour pressure value for the test item.

Conclusions:
The vapour pressure of the test item has been determined to be 1.2 x 10-4 Pa at 25 °C.
Executive summary:

The vapour pressure was determined according to OECD TG 104 to be 1.2 x 10-4 Pa at 25 °C. Measurements were made at several temperatures using a vapour pressure balance. The vapour pressure at 25 °C was extrapolated from the measurements using linear regression analysis.
