Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A study was conducted to determine the vapour pressure. Using the dynamic method the vapour pressure was determined in 8 measurements in a temperature range from 71 to 163 °C. Using the Ebulliometric determination method the correlation constants were determined and the vapour pressure at 20 °C was calculated to be 0.012629 mBar. In addition the GESTIS database reports the vapour pressure at 20 °C to be 0.05 mBar. Thus, as the vapour pressure values were close to each other, the calculate value was regarded as reliable and was chosen as key parameter.
