- Conclusions:
- The vapour pressure of the test item was determined to be 7.3E-7 Pa at 20 °C, 1.7E-6 Pa at 25 °C and 8.7E-5 Pa at 50 °C, respectively.
- Executive summary:
A study was conducted according to OECD TG 104 and Guideline 67/548/EEC Annex V method A.4 to determine the vapour pressure of the test item. The vapour pressure was measured in the temperature range of 32 °C to 130 °C using the effusion method. Above 75 °C a vapour pressure could be measured. The vapour pressure was calculated using the linear regression equation of the Log P versus 1/T function. The vapour pressure of the test item was determined to be 7.3E-7 Pa at 20 °C, 1.7E-6 Pa at 25 °C and 8.7E-5 Pa at 50 °C, respectively.
