- Identification: FAT 11127/E TE
Lot.: 2024 (Thailand)
Appearance: Dark blue powder
MF = C39H20Cu2N5Na3O15S3
MW = 1090.86 g/mol - Temp.:
- 25 °C
- Vapour pressure:
- > 0 Pa
- Conclusions:
- Pvp = 3.35 x 10E-43 Pa at 25 °C = 2.51 x 10E-45 mm Hg at 25 °C based on the boiling point calculated by MPBPWIN v1.43 and using the Modified Watson Correlation.
Pvp = 2.84 x 10E-44 Pa at 25 °C = 2.13 x 10E-46 mm Hg at 25 °C (Grain-Watson Method)
Pvp: 2.04 x 10E-50 mm Hg (modified Grain Method)
Pvp: 1.54 x 10E-46 mm Hg (Mackay Method) - Executive summary:
The vapor pressure (Pvp)of FAT 11127/E TE was calculated at 25°C as per OECD test 104 and EU method A.4. The vapor pressure is a function of the temperature and is specified in Pascal (Pa) or in mm Hg.
If the vapor pressure of substance is expected to be so small that the value is below the measurement range of an experimental determination, then the vapor pressure can also be calculated, using the Modified Watson Correlation or by using a calculation program such as EPI-Suite, MPBPWIN v1.43.
Boiling point calculated by EPI suite was found to be 1751 °C = 2024 K
Vapour pressure calculation results :
Pvp = 3.35 x 10E-43 Pa at 25 °C = 2.51 x 10E-45 mm Hg at 25 °C based on the boiling point calculated by MPBPWIN v1.43 and using the Modified Watson Correlation.
Pvp = 2.84 x 10E-44 Pa at 25 °C = 2.13 x 10E-46 mm Hg at 25 °C (Grain-Watson Method)
Pvp: 2.04 x 10E-50 mm Hg (modified Grain Method)
Pvp: 1.54 x 10E-46 mm Hg (Mackay Method)
As expected, the vapor pressure is well below the measurement range of experimental determination (e.g. the gas saturation method), therefore the vapor pressure was calculated using the methods given above.
Reference
The calculated boiling point was found to be : 1751°C = 2024 K
Polarity of the test item = 1.09 which was considered for calculation of emprical factor (Kf)
As expected, the vapor pressure is well below the measurement range of experimental determination (e.g. the gas saturation method), therefore the vapor pressure was calculated using the methods given in result above.
Description of key information
Since no boiling point could be determined and the melting point determined at 254 °C justifies a calculation of hte vapour pressure instead of measuring it, the vapour pressure was deermined according to different calculation models resulting in the following values:
Pvp = 3.35 x 10E-43 Pa at 25 °C = 2.51 x 10E-45 mm Hg at 25 °C based on the boiling point calculated by MPBPWIN v1.43 and using the Modified Watson Correlation.
Pvp = 2.84 x 10E-44 Pa at 25 °C = 2.13 x 10E-46 mm Hg at 25 °C (Grain-Watson Method)
Pvp: 2.04 x 10E-50 mm Hg (modified Grain Method)
Pvp: 1.54 x 10E-46 mm Hg (Mackay Method)
Key value for chemical safety assessment
