The data have been obtained by using the Antoine-Equation. The following Antoine coefficient A and B were obtained: 8.0187 (A); 2071.7 (B)

Conclusions:

The vapour pressure was calculated to be 0.8 hPa at 25 °C.

Executive summary:

The dynamic method was used to determine the vapour pressure at 25 °C which conforms with the procedure 'Test method A.4', described in the ECGuideline. Using the Antoine coefficients of the regression straight line the vapor pressure was calculated to be 0.8 hPa at 25 °C.

Description of key information
