- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Version / remarks:
- 1996
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- effusion method: isothermal thermogravimetry
- Specific details on test material used for the study:
- Decomposition temperature: ca. 200°C.
- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- 0.001 Pa
- Key result
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- 0.002 Pa
- Conclusions:
- The vapour pressure of the substance at 20°C was determined to be 8.4E-4 Pa.
The vapour pressure of the substance at 25°C was determined to be 1.6E-3 Pa. - Executive summary:
The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion
method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950.
The constants specific for the experimental arrangement were determined using a set of 5 reference
compounds. A vapour pressure curve for the test item was constructed from duplicate measurements
at 90°C, 100°C, 110°C and 120°C. The vapour pressure of the substance at 20°C and 25°C was
determined by extrapolation to be 8.4E-4 Pa and 1.6E-3 Pa, resp.
