yes
Type of method:
effusion method: vapour pressure balance
Temp.:

Vapour pressure:
ca. 0 Pa
Remarks on result:
other: extrapolated value

Main sequence

A total of ten runs were completed for the main sequence. Equilibrium with regard to vapour pressure was assessed to have been reached over the final five runs. Thus the final five runs have been used to calculate the definitive vapour pressure value for the test item.

Conclusions:
The vapour pressure of the test item has been determined to be 1.2 x 10-4 Pa at 25 °C.
Executive summary:

The vapour pressure was determined according to OECD TG 104 to be 1.2 x 10-4 Pa at 25 °C. Measurements were made at several temperatures using a vapour pressure balance. The vapour pressure at 25 °C was extrapolated from the measurements using linear regression analysis.
