- Conclusions:
- The vapour pressure of the test substance was determined to be 2,300 and 11,600 Pa at a temperature of 20°C and 50°C, respectively.
- Executive summary:
A study was conducted to determine the vapour pressure of the test substance using dynamic method, in accordance with OECD Guideline 104. Based on a series of 6 - 15 differential scanning calorimetrie measurements of the boiling temperature at different pressures between 103 and 105 Pa , a vapour pressure curve [log p = f(1/T)] was generated, from which the vapour pressure value was extrapolated. The vapour pressure of the test substance was determined to be 2,300 and 11,600 Pa at a temperature of 20°C and 50°C, respectively (Kintrup, 2015).
