Description of key information

The vapour pressure of the test substance was determined to be 0.47 hPa at 20 °C, 0.60 hPa at 25 °C and 1.99 hPa at 50 °C.

Key value for chemical safety assessment

Vapour pressure:

at the temperature of:
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 pressure range between 13 to 69 hPa. 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 was determined to be 0.47 hPa at 20 °C, 0.60 hPa at 25 °C and 1.99 hPa at 50 °C.
