Thermal Stability

The test item in a closed glass crucible showed no thermal effects in the temperature range of 25 - 300 °C.

Conclusions:
A vapour pressure of 1.69 hPa, 2.2 hPa and 7.25 hPa at 20 °C, 25 °C and 50 °C was observed.
Executive summary:

The vapour pressure of the test substance was determined in accordance with OECD guideline 104 (2006) by applying the dynamic method. The vapour pressure of the test substance was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25, and 50 °C and revealed values of 1.69, 2.2 and 7.25 hPa, respectively.

Description of key information

A vapour pressure of 1.69 hPa, 2.2 hPa and 7.25 hPa at 20 °C, 25 °C and 50 °C was observed.
