Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
other: GLP compliant guideline study, available as unpublished report, no restrictions, fully adequate for assessment.
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
GLP compliance:
yes (incl. QA statement)
Type of method:
static method
Key result
Temp.:
20 °C
Vapour pressure:
3.85 kPa
Key result
Temp.:
20 °C
Vapour pressure:
28.9 mm Hg
Conclusions:
The vapour pressure at 20 °C (293K) was 3.85 kPa (28.9 mm Hg).
Executive summary:

Vapour pressure was determined using the static method. The test sample was heated from 20°C to 100°C with a heating rate of 2°C / min and measurement every 10°C. The vapour pressure was calculated using regression analysis. The vapour pressure at 20°C (293K) was 3.85 kPa (28.9 mm Hg).
