- Vapour pressure:
- 325.5 Pa
- Conclusions:
- The test item vapour pressure is estimated to be 108.9 Pa at 20°C and 150.9 Pa at 25°C.
- Executive summary:
The test item vapour pressure was determined with the static method according to recognised guideline under GLP. No deviation from the guideline was observed in the study.
Experimental vapour pressures have been measured between 30.8°C and 51°C. The data obtained have been used to build a Clausius-Clapeyron plot (log p [p in Pa] versus 1/T [T in K]). All the experimental data have been used for this regression.
Interpolation using this regression function yields an estimated vapour pressure of 108.9 Pa at 20°C and 150.9 at 25°C.
Reference
The corrected vapour pressures were plotted in a Clausius-Clapeyron plot (log p [p in Pa] versus 1/T [T in K]). All the experimental data have been used for this regression.
Interpolation using this regression function yields an estimated vapour pressure of 108.9 Pa at 20°C and 150.9 at 25°C.
Description of key information
The vapour pressure of the test item was determined in an experimental key study of Klimisch validity 1.
Key value for chemical safety assessment
- Vapour pressure:
- 108.9 Pa
- at the temperature of:
- 20 °C
