Type of method:
effusion method: isothermal thermogravimetry
Test material information:
Composition 1
Specific details on test material used for the study:
Decomposition temperature: ca. 200°C.
Key result
Test no.:
#1
Temp.:
20 °C
Vapour pressure:
0.001 Pa
Key result
Test no.:
#2
Temp.:
25 °C
Vapour pressure:
0.002 Pa
Conclusions:
The vapour pressure of the substance at 20°C was determined to be 8.4E-4 Pa.
The vapour pressure of the substance at 25°C was determined to be 1.6E-3 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.

The constants specific for the experimental arrangement were determined using a set of 5 reference

compounds. A vapour pressure curve for the test item was constructed from duplicate measurements

at 90°C, 100°C, 110°C and 120°C. The vapour pressure of the substance at 20°C and 25°C was

determined by extrapolation to be 8.4E-4 Pa and 1.6E-3 Pa, resp.
