Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A total of 7 runs were completed for the main sequence. Runs 1 to 3 were not used as the vapor pressure had not equilibrated. The final 4 runs were used as equilibrium had been reached.

Run       Log10 [Vp(25 ºC)]

4              -1.37

5              -1.39

6              -1.43

7              -1.40

Mean       -1.40

Vapor Pressure = 4.01 x 10-2 Pa

Vapour pressure at 25 degrees Celcius: 4.01 x 10-2 Pa
