Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Apr 1994
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
Boiling point method: Fluid boils when it is heated and its vapor pressure becomes equal to external pressure above it. Temperature measured at that point is the boiling point. A vapor pressure curve can be drawn by determining the boiling point at various pressures (external pressure).
GLP compliance:
no
Type of method:
other: Boiling point method
Key result
Temp.:
25 °C
Vapour pressure:
0.002 mm Hg
Remarks on result:
other: Extrapolation value obtained by calculation
Conclusions:
The vapour pressure of the test item was determined as 0.002 mmHg (0.26 Pa) at 25°C (Extrapolation value obtained by calculation).
