Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Study period:
- 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Calculations were performed using the melting and boiling point temperatures (lowest estimates due to decomposition) and equations which were based on the equation reported in the OECD 104 guideline. The equations were further refined to result in more precise results.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- improved Grain-Watson estimation was used
- Principles of method if other than guideline:
- An estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure” ANNEX Estimation Method newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000, Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 – 65) was used. This method is applied for vapour pressures between 10^3 to 10^-7 mbar. This deviates from the older version published in OECD Guideline 104. It was used due to the differentiation between solids and liquids, which results in a more precise estimate.
This method uses the melting and the boiling temperatures. - GLP compliance:
- no
- Temp.:
- 20 °C
- Vapour pressure:
- <= 0.041 Pa
- Transition / decomposition:
- yes
- Transition temp.:
- 200 °C
- Conclusions:
- vapour pressure: <=0.041 Pa
- Executive summary:
In the Klimisch 2 non-GLP study from Kintrup (2012) the vapour pressure of Sodium dicyclohexyl sulfosuccinate was calculated using the melting and boiling point. An estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure” ANNEX Estimation Method newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000, Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 – 65) was used. This method is applied for vapour pressures between 10^3 to 10^-7 mbar. This deviates from the older version published in OECD Guideline 104. It was used due to the differentiation between solids and liquids, which results in a more precise estimate.
Using a melting point of 200°C and a boiling point of 247 °C (both values might be underestimations due to decomposition) resulted in a finding that the test item has a vapour pressure of ≤ 4.1*10 -2 Pa at 20 °C according to the definition in the OECD Guideline 104 (Grain-Watson estimation).
This value is considered reliable for the further risk assessment.
Reference
The vapour pressure was calculated using the melting point of 200 °C and the boiling point of 247°C.
The test item Sodium dicyclohexyl sulfosuccinate has a vapour pressure of ≤ 4.1*10-7atm (≤ 4.1*10-2Pa; ≤ 4.1*10-4mbar) at 20 °C (the calculation is based on lowest possible melting and boiling temperature) according to the definition in the OECD Guideline 104 (Grain-Watson estimation).
Description of key information
