Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
26 September 2017 to ****
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Deviations:
no
GLP compliance:
yes
Type of method:
effusion method: Knudsen cell
Specific details on test material used for the study:
Physical state: Dark amber liquid
Purity: >93 %
Key result
Temp.:
20 °C
Vapour pressure:
0 Pa
Key result
Temp.:
25 °C
Vapour pressure:
0 Pa

The IR spectra revealed no difference between the untested, tested and control samples, and so it was concluded that no degradation of the sample had occurred during testing. No claim of GLP compliance is made for the IR data, as the instrument was not fully validated before use.

Conclusions:
The vapour pressure of the test substance has been determined to be 0.000024 Pa at 20 °C and 0.000044 Pa at 25 °C.
Executive summary:

In a study performed to the standardised guideline OECD 104, under GLP conditions, the vapour pressure of the test substance has been determined to be 0.000024 Pa at 20 °C and 0.000044 Pa at 25 °C, Smithers Viscient (ESG) Ltd. (2018).
