Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The regression of the results leads with a mean deviation of 0.91 % to the following rounded equation:

ln(p/hPa) = 9.2464 - 3502.69 / (190.12 + t/°C)

The vapour pressure at 20 °C, 25 °C and 50°C was calculated from the regression equation.

The normal boiling temperature was obtained by intrapolation from the vapour pressure curve.
