Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 1994-01-06 to 1994-01-18
- 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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: Estimation method
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The vapour pressure of the test item is below 5.6E-5 Pa at 25 °C.
- Executive summary:
A study was conducted to determine the vapour pressure of the test item according to Regulation (EC), method A.4. and OECD 104. As the test item is thermally labile, the procedure described in Handbook of Chemical Property Estimation Methods, W.J. Lyman, W.F Reehl, P.H. Rosenblatt, McGraw-Hill (1982), chapter 14, based on the modified Watson Correlation was used to determine the saturated vapour pressure : at 298 K (25 °C ) is below 5.6 x 10-5 Pa (4.1 x 10-7 mm Hg)
