Description of key information

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 to be 22.7 Pa, 31.8 Pa and 147 Pa respectively.

Key value for chemical safety assessment

Vapour pressure:

Additional information

A study was conducted according to OECD Test Guideline 104 (2006), Regulation (EC) No 440/2008 method A.4 and OPPTS 830.7950 to determine the vapour pressure of the test item. Therefore the vapour pressure was measured in the temperature range of 87 to 168 °C. From the measured data points of the vapour pressure curve the constants A, B and C of the Antoine equation was derived by regression of the data points. The vapour pressure was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C to be 22.7 Pa, 31.8 Pa and 147 Pa respectively. No observations were made which might cause doubts concerning the validity of the study outcome.
