Any other information on results incl. tables
The log PT versus 1/T curve for the substance over the range 30 -50°C showed poor linearity (correlation coefficient r < 0.99). Extrapolation of the curve to 20°C or 25°C would not give reliable results for the vapour pressure of the substance at these temperatures. Since the weight losses of the test item at 30°C, 40°C and 50°C were lower than the weight losses of reference substance napthalene at the same temperatures, it was concluded that vapour pressure of the substance at 20°C (25°C) is lower than the vapour pressure of napthalene at 20°C (25°C).
The observed weight losses from 50°C were slightly non-linear. The test item is a UVCB. Observed weight losses might have been slightly influenced by the loss of low-molecular-weight components or by reaction and/or decomposition of the test item. During the determination of the vapour pressure, the test item was kept at elevated temperatures for a longer time than during the melting and boiling temperature study. Reaction and/or decomposition might, therefore, have occurred at lower temperatures than during the determination of the melting and boiling point (i.e. 75°C).
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance at 20°C was determined to be < 7.56 Pa.
The vapour pressure of the substance at 25°C was determined to be < 11.5 Pa. - Executive summary:
The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950.
From the measured weight losses in the temperature range 30 -50°C, the vapour pressure of the substance was determined to be lower than the vapour pressure of reference substance Napthalene.
The vapour pressure of the substance at 20°C and 25°C was concluded to be < 7.56 Pa and < 11.5 Pa, resp.
