Any other information on results incl. tables
The weight losses of the test substance at 110°C, 120°C, 130°C and 140°C were lower than the weight losses of hexachlorobenzene at the same temperatures. From this it was concluded that vapour pressure of the substance at 20/25°C is lower than the vapour pressure of hexachlorobenzene at 20/25°C (see the table above).
Applicant's summary and conclusion
- Conclusions:
- In a GLP-compliant study in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950 using the isothermal thermogravimetric effusion method, the vapour pressure of the substance at 25°C has been determined as < 7.0E-03 Pa. The vapour pressure of the substance at 20°C has been determined as < 1.5E-03 Pa.
