Description of key information

The vapour pressure of the test substance was determined to be 0.66 hPa at 20 °C, 0.87 hPa at 25 °C and 3.03 hPa at 50 °C.

Key value for chemical safety assessment

Vapour pressure:

20 °C

Additional information

A study was conducted according to OECD TG 104 to determine the vapour pressure of the test item using the dynamic method (VLE). A vapour pressure curve with 9 data points was measured over a temperature range between 78.3 to 129.5 °C. The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C. The vapour pressure of the test substance was determined to be 0.66 hPa at 20 °C, 0.87 hPa at 25 °C and 3.03 hPa at 50 °C.
