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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The value of the vapour pressure of SETAFIX X 11342 at 20°C was determined to be: 0.019 (+/-0.3) Pa at 20 °C
Key value for chemical safety assessment
- Vapour pressure:
- 0.019 Pa
- at the temperature of:
- 20 °C
Additional information
Because the measured vapour pressure at 24.97°C were <0.1Pa, a correction according to Bennett and Tompkins (Trans Faraday Soc., 1957, 53, 185) for thermal transpiration was made.
The test substance was considered to show ideal behaviour. Thus the vapour pressure curve was derived by using a least squares method to calculate a straight line that best fits the measured data (Clapeyron).
The vapour pressure at 20°C was extrapolated from the resultant vapour pressure curve.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
