- Vapour pressure:
- 0 Pa
- Temp.:
- 30 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- The vapour pressure of the substance was measured at 0.0000019 Pa at 20 °C, 0.0000047 Pa at 25 °C and 0.000011 Pa at 30 °C.
- Executive summary:
The vapour pressure of the substance was determined according to the EU guideline A.4 using the Differential Scanning Calorimeter (DSC) in correspondance to the Knudsen effusion method as described in the OECD Testing Guideline 104.
The temperature dependence of the vapor pressure of the test item was determined with the Knudsen effusion method using a vapor pressure balance in the temperature range 128-163 °C.
The following vapor pressures were calculated for 20, 25 and 30 °C using a semilogarithmic linear regression based on the Antoin equation to be:
P20 = 0.0000019 Pa
P25 = 0.0000047 Pa
P30 = 0.000011 Pa
