Temp.:
20 °C
Vapour pressure:
60 Pa
Remarks on result:
other: Mean of runs 1 and 2

Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; P in mbar and T in Kelvin). The vapour pressure at 20°C was extrapolated from the vapour pressure curve to be 60 Pa.

Conclusions:
The vapour pressure of the substance was extrapolated from the vapour pressure curve to be 60 Pa at 20 °C.

Description of key information

The vapour pressure of amides, C12-18 (even-numbered), N-[3-(dimethylamino)propyl], N'-oxides was determined in a GLP study according to test method EC A.4 to be 60 Pa at 20 °C, following the static technique (Younis, 2013).

Key value for chemical safety assessment
