20 °C

Additional information

A study was conducted to determine the vapour pressure of the test substance. A vapour pressure curve from 10 °C – 280 °C was recorded and the parameters of the Antoine equation were calculated. Using the Antoine equation the vapour pressure at 20 °C was calculated to be 5.33 hPa and at 50 °C the vapour pressure was calculated to be 29.83 hPa. Furthermore the GESTIS database reports the vapour pressure to be 5.2 hPa at 20 °C. The literature data support the experimental determined value. Thus, a 5.33 hPa was chosen as key value for chemicals safety assessment.
