Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
December 2013 - February 2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Well conducted study performed according to established method.
Qualifier:
according to guideline
Guideline:
other: dynamic method (ebulliometer)
Deviations:
no
Principles of method if other than guideline:
The vapor pressure was measured by means of a dynaimic method with an ebulliometer. With this equipment, vapor pressure of pure components or defined mistures can be experimentally determined in a temperature range of approx. 50 to 620 K and at pressure from about 2mbar up to 1 bar. At a given pressure, the boiling temperatures are measured.
GLP compliance:
not specified
Type of method:
dynamic method
Remarks:
dynamic method with an ebulliometer
Temp.:
25 °C
Vapour pressure:
0.066 mm Hg
Conclusions:
The vapor pressure measured by means of a dynamic method with an ebulliometer for two samples of the registered substance was 0.062 and 0.069 mmHg at 25 degrees Celsius, with an average value of 0.0655 mmHg.
Executive summary:

The vapor pressure measured by means of a dynamic method with an ebulliometer for two samples of the registered substance was 0.062 and 0.069 mmHg at 25 degrees Celsius, with an average value of 0.0655 mmHg.
