Key result

Temp.:

20 °C

Vapour pressure:

0.64 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 39 °C -137 °C and 38 °C - 121 °C for run 1 and run 2, respectively. The vapour pressure at 20 °C was extrapolated from the vapour pressure curve to be 0.61 mbar (run 1) and 0.67 mbar (run 2).

Conclusions:

The vapour pressure of the test substance was extrapolated from the vapour pressure curve to be 0.64 mbar at 20 °C.

Description of key information

The vapour pressure of the test substance was determined in a GLP study according to test method EC A.4 to be 0.064 kPa at 20 °C, following the static technique (Younis, 2011).
