Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- December 1992
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Version / remarks:
- August 1996
- Deviations:
- no
- Principles of method if other than guideline:
- The vapour pressure was estimated based on the boiling point calculated and using Modified Watson Correlation.
- GLP compliance:
- not specified
- Type of method:
- other: Estimation of vapour pressure based on boiling point calculated and using Modified Watson Correlation
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The vapour pressure of Urea 4 was estimated to be < 2 E-12 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation.
- Executive summary:
The vapour pressure of Urea 4 was estimated according to EU method A.4, OECD Guideline 104, and EPA OPPTS 830.7950 guideline. The vapour pressure of Urea 4 was estimated to be < 2 E-12 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation. From this result, it can be concluded that the vapour pressure of Urea 4 is too low to have any relevant effect on the environment.
