Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14th January 1993 to 18th May 1994
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Key result
- Transition / decomposition:
- no
- Conclusions:
- The vapour pressure of the test material was estimated to be 0.0001874 Pa at 25 °C.
- Executive summary:
The vapour pressure of the test material was evaluated in a study conducted in accordance with EU Method A.4 using the effusion method: vapour pressure balance. Under the conditions of the test, the vapour pressure of the test material was determined to be 1.874E-04 at 25 °C.
Reference
The viscous liquid sample was maintained below 100.75 °C while establishing the vapour pressure relationships. The sample remained in the oven at the end of the experiments and there were no obvious signs of decomposition during the test.
Sputtering and some condensation of sample onto the balance pan was observed, but the mass difference method alone was used to determine the vapour pressures.
In Run 1, the mass difference at ambient temperature (23.6 °C) was 1.4 µg resulting in a vapour pressure of 1.82E-03 Pa.
A vapour pressure curve was not used in Run1 to provide a room temperature value of vapour pressure.
The degassing was subsequently confirmed by Run 2, in which the initial measured mass difference was only around 0.2 µg at 26.1 °C. Run 2 and subsequently Run 3 (initial measured value 0.16 µg at 27 °C), covered the temperature range up to about 100 °C with comparable mass differences agreeing within a factor of about two or better. Less statistical error occurred in Run 2 in attempts at extrapolation. The following vapour pressure was extrapolated from Run 2:
Vp (25 °C) = 1.874E-04 Pa
With slope around -3779K and calculated error range of about 6 % (compared to Run 3 with an error range of 14 %).
