Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-11-17 - 2018-01-09
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- yes
- Remarks:
- When the study plan was prepared the test item was identified by m- & o-terphenyl rxn mass only. Subsequently a batch number and appearance became available and these have been included in the report.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- When the study plan was prepared the test item was identified by m- & o-terphenyl rxn mass only. Subsequently a batch number and appearance became available and these have been included in the report.
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Remarks:
- The vapor pressure was determined using a vapor pressure balance
- Specific details on test material used for the study:
- Identification: m- & o-terphenyl rxn mass
Appearance/Physical state: Cream colored solid
Storage conditions: Approximately 4 °C, under nitrogen in the dark - Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.018 Pa
- Remarks on result:
- other: mean of 5 measurements
- Conclusions:
- The vapor pressure of the test item has been determined to be 0.0182 Pa at 25 ºC.
- Executive summary:
The vapor pressure of test item has been determined according to GLP to be 1.82 x 10-2Pa at 25 °C, using the vapor pressure balance method designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.

Summary of Results
The values of vapor pressure at 25 °C extrapolated from each graph of 5 measurements are summarised in the following table:
Run | Log10 [VP (25 °C)] |
1 | -1.70 |
5 | -1.70 |
6 | -1.83 |
7 | -1.70 |
8 | -1.77 |
Mean |
-1.74 |
Vapour pressure | 1.82 x 10 -2 Pa |
Discussion
The test item did not change in appearance under the conditions used in the determination.
The un-shaded points on the graphs have not been used in the data analysis. The omission of these points is justified due to the fact that typically, the first few points on a run can be erroneous due to the system undergoing a process of settling.
A total of 8 runs were completed for the main sequence. Runs 2,3 and 4 have not been used due to the nonlinear plots obtained. The remaining runs have been used to calculate the definitive vapor pressure value for the test item.
The results may represent rounded values obtained by calculations based on the exact raw data.
Conclusion
The vapor pressure of the test item has been determined to be 1.82 x 10-2 Pa at 25 ºC.
