Any other information on results incl. tables
In the range of 160°C and 190°C, the log p versus 1/T curve had a coefficient of correlation (r) of < 0.99. Since no accurate vapour pressure could be calculated from the obtained results, the weight losses were compared with the results of chrysene. Since the weight loss of the test item was lower than the weight loss of the reference compound the vapour pressure of the test item is considered to be below the vapour pressure of chrysene.
Applicant's summary and conclusion
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of the substance. This was determined to be < 8.4x10^-7 at 20°C and < 1.1x10^-6 at 25°C indicating low vapour pressure of the substance.
