Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From March 22, 2017 to March 28, 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Type of method:
- other: Clapeyron-Clausius equation
- Temp.:
- 25 °C
- Vapour pressure:
- 0.45 kPa
- Conclusions:
- According to OECD The Guidelines for the Testing of Chemicals 104 Vapour pressure, the saturated vapour pressure of Eversorb 109 were 0.45 kPa at 25.0°C.
- Executive summary:
The vapour pressure of Eversorb 109 was determined according to OECD The Guidelines for the Testing of Chemicals 104 Vapour pressure (2016). Based on the results that thevapour pressure of Eversorb 109 were 0.43 kPa at 20.0°C, 0.52 kPa at 40.0°C and 0.58 kPa at 50.0°C, the data was plotted to gain fitting curve equation. Therefore, the saturated vapour pressure of Eversorb 109 was 0.45 kPa at 25.0°C.
