Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
GLP compliance:
yes
Type of method:
effusion method: vapour pressure balance
Temp.:
20 °C
Vapour pressure:
0 hPa
Temp.:

Conclusions:
The vapour pressure determined with the vapour pressure balance method was 1.35 x 10-9 hPa at 25°C.
Executive summary:

The vapour pressure determined with the vapour pressure balance method was 1.35 x 10-9 hPa at 25°C (Bayer, 1992).

Description of key information

The vapour pressure determined with the vapour pressure balance method was 1.35 x 10-9 hPa at 25°C (Bayer, 1992).

Key value for chemical safety assessment

Vapour pressure:
0 hPa
at the temperature of:
25 °C

Additional information

Gas saturation method delivered another result of <2.27 x 10-6 hPa at 25°C (Monsanto, 1980). Although this is about 1000 times higher than the one mentioned in key study, these two results are both far below 1 Pa indicating a very low vapour pressure.
