Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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
- Type of method:
- effusion method: vapour pressure balance
- Temp.:
- 20 °C
- Vapour pressure:
- < 1 Pa
- Conclusions:
- The vapor pressure data between 100 and 160 °C seem to be most representative of the pure test item. At lower temperatures residual moisture determines the vapour pressure. Extrapolation of the vapour pressure data > 100 °C to 20 °C gives a calculated data of approximately 40 µPa. However, due to the analytical range of the system and own experience it is concluded that the vapour pressure of the test item is < 1 Pa at 20 °C.
- Executive summary:
The vapour pressure of the test substance was determined according to the OECD Guideline 104 by means of the effusion method using a vapour pressure balance. Vapour pressure was determined in four measurements in a temperature range from 20 to 160 °C. The test sample obviously contained a significant level of residual moisture. At lower temperatures residual moisture determines the vapour pressure. Extrapolation of the vapour pressure data > 100 °C to 20 °C gives a calculated data of approximately 40 µPa. However, due to the analytical range of the system and own experience it is concluded that the vapour pressure of the test item is < 1 Pa at 20 °C.

1)Mean value of triplicate measurements
Probably the sample contained too much resuidual moisture. During the measurement the water content decreased and the vapour pressure did not increase significantly despite the increasing temperature. The measurement was aborted at 80 °C due to failure of the instrument.

1)Mean value of triplicate measurements
2)Data could not be saved
Due to the extensive degassing procedure the sample contained not so much residual moisture. Despite increasing temperature the vapour pressure decreased in the range of 30 to 70 °C, but strong increase of the vapour pressure above 100 °C. The sample showed a foamed appearance after the emasurement.

1)Mean value of triplicate measurements
The sample was degassed in the measuring system for 6 days at room temperature. At lower temperatures no signal was detected. In the medium temperature range the vapour pressure was measured close to the data of the second measurement. At 170 °C the signal was too large for the system. Maybe decomposition starts at this temperature which would be in accordance with thermogravimetric measurements.
The measurements in the medium temperature range were repeated subsequently from 70 °C to 110 °C.
Description of key information
Extrapolation of the vapour pressure data > 100 °C to 20 °C gives a calculated data of approximately 40 µPa for the source substance. However, due to the analytical range of the system and own experience it is concluded that the vapour pressure of the test item is < 1 Pa at 20 °C.
The same result can be expected for the target substance.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
