Results
The test item has a vapour pressure of ≤ 6.8E-04 Pa at 20 °C and of ≤ 1.9E-02 Pa at 50 °C (the calculation is based on the lowest possible 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 is not in the recommended range of 1 to 1000 mbar for DSC-measurement. 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 23^rdMarch 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 1E03 to 1E-07 mbar.
