Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- 23rd March 2006
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).
- Principles of method if other than guideline:
- This method can be used to measure the vapour pressure of any pure substance within the following pressure/temperature range:
Boiling temperature range: from approx. 20 °C to 500 °C
Pressure range: from approx. 1E-1 to 7E3 kPa (= 1 mBar to 70 Bar)
In accordance to the REACH guideline annex VII 7.5 “the study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or recognised calculation method is sufficient”.
Also if the experimentally determined vapour pressure of the test item is not definable in the recommended range of 1 to 1000 mBar for DSC-measurements, an estimation procedure can be used.
The calculation should be conducted in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23rd 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). This method is applied for vapour pressures between 1E3 to 1E-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. - GLP compliance:
- no
- Type of method:
- other: Grain-Watson Estimation method
- Remarks:
- Calculation based on the lowest possible measured boiling temperature.

Any other information on results incl. tables
The test item has a vapour pressure of 9.9E-6 atm (1.0 Pa; 1E-2 mBar) at 20 °C and of 2.2E-4 atm (23 Pa; 2.3E-1 mBar) at 50 °C (the calculation is based on the lowest possible boiling temperature) according to the definition in the OECD Guideline 104 (Grain-Watson estimation).
The experimentally determined vapour pressure of the test item at 20 °C (by means of DSC) is not in the recommended range of 1 to 1000 mBar for DSC-measurements.
Therefore an estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23rd 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 1E3 to 1E-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.
Remarks:
Substances with a higher vapour pressure need to be assessed more critically, e.g. concerning the release of toxic substances, than those with a lower vapour pressure.
