Key result

Temp.:

20 °C

Vapour pressure:

0.017 mBar

Remarks on result:

other: The result is the mean of 2 runs.

Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; p in mbar and T in Kelvin). The temperature range was 18.7 °C - 64.8 °C and 18.6 °C - 70 °C for run 1 and run 2, respectively.

The vapour pressure at 20°C was interpolated from the vapour pressure curve to be 0.017 mbar (run 1) and 0.016 mbar (run 2 ).

Conclusions:

The vapour pressure of the substance was interpolated from the vapour pressure curve to be 0.017 mbar (1.7 Pa) at 20°C

Description of key information

The vapour pressure of the test substance was determined in a GLP-compliant study according to test method EC A.4 to be 1.7 Pa at 20 °C, following the static technique (Younis S, 2012).
