Additional information

The vapour pressure of the test item was determined via vapour pressure balance (effusion method; OECD guideline 104 and EU-Method A.4) in the temperature range of 16 to 138°C. Two measurements were carried out (test item was degassed under vacuum; first run and without degassing; second run). No signal was observed up to a temperature of 39°C. Above 43°C, a vapour pressure could be measured. Based on the experimentally derived results and using the Antoine equation the vapour pressure at 20, 25, and 50°C were calculated. The test item shows a very low vapour pressure at ambient temperature (20°C: 4.4 x 10E-6 hPa, 4.4 x 10E-4 Pa; 25°C: 6.7 x 10E-6 hPa, 6.7 x 10E-4 Pa).
