Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the melting point is above 300°C
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 29 June 2017 to 4 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: Knudsen cell
- Specific details on test material used for the study:
- Batch: 16021
Appearance: white solid
Purity: 86.25 %
Conditions of storage: Storage at room temperature, 15 to 30 ºC
Date of expiry: 30/05/2018 - Conclusions:
- Two vapour pressure determinations were performed on the test item using the Knudsen cell effusion method described in OECD Guideline 104. One determination was performed at 50-53 °C, and one at 50-53 °C. In both runs an initial small weight loss was recorded, after which no significant weight losses were recorded due to the vapour pressure being too low. Due to the limited data and low pressures, the vapour pressure of the test material at 20 °C and 25 °C could not be accurately extrapolated from the ln VP vs 1/T graph, and was therefore not determined and reported.
- Executive summary:
Two vapour pressure determinations were performed on the test item using the Knudsen cell effusion method described in OECD Guideline 104. One determination was performed at 50-53 °C, and one at 50-53 °C. In both runs an initial small weight loss was recorded, after which no significant weight losses were recorded as the vapour pressure was so low. Due to the limited data and low pressures, the vapour pressure of the test material at 20 °C and 25 °C could not be accurately extrapolated from the ln VP vs 1/T graph, and was therefore not determined and reported.

The first run was performed between 50 °C and 53 °C and the second test at 50 °C and 53 °C. The first run was carried out between 15 August 2017 and 16 August 2017 (a total of 22 hours and 5 minutes) with most readings taken on the first day. The second run was carried out between 16 August 2017 and 21 August 2017 (a total of 113 hours and 55 minutes) with readings being taken on all days except 19 and 20 August 2017. The longer period was used for the second test to allow more time between readings.
In both runs an initial small weight loss was recorded, after which no significant weight losses were recorded as the vapour pressure was so low. The second run was carried out to confirm the data from the first run.
The temperature could not be raised due to the thermal events found when performing the DSC analysis (thermal events started at 67 °C). Due to the limited data and low pressures the vapour pressure of the test material at 20 °C and 25 °C could not be accurately extrapolated from the ln VP vs 1/T graph. After the second run the test crucible was opened and there were no signs of degradation of the test substance. The IR spectra for the tested and control material revealed no differences; therefore the test material was considered stable for the duration of the test.
Description of key information
The study does not need to be conducted as the substance has a melting point above 300 oC. Nevertheless a study was conducted according to OECD Guideline 104. Due to the limited data and low pressures, the vapour pressure of the test material at 20 °C and 25 °C could not be accurately determined. However a worst-case vapour pressure value of 10-5 Pa is included to address the requirements of the chemical safety assessment.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
