- Conclusions:
- The vapour pressure of test substance was extrapolated to be 2.3 Pa at 20°C and 3.7 Pa at 25°C
- Executive summary:
In this OECD 104 guideline study, the vapour pressure of the test material was determined to be 2.3 Pa at 20 ºC and 3.7 Pa at 25 ºC.
Reference
Vapor pressures were calculated using a molar mass of 164.16 g/mol.
The regression of the vapor pressure data leads with a mean deviation of 2.52 % to the following equation:
ln(p/hPa) = 13.2756 - 2982.67 / (154.87 + t/°C)
The vapor pressures were calculated from the regression equation.
Description of key information
Study carried out according to guideline and with GLP compliance.
Key value for chemical safety assessment
- Vapour pressure:
- 2.3 Pa
- at the temperature of:
- 20 °C
Additional information
The determination was conducted by the gas saturation method.
Vapour pressure: 3.7 Pa at 25°C (extrapolated)
