For every temperature, a minimum
of three measurements were performed.
According to OECD Guideline 104
the vapor pressure is measured as 3.2 Pa at 20 °C, 32.3 Pa at 50 °C and
46.6 Pa at 55 °C. In this method, appropriate for accurate measurements
down to 0.1 Pa, the compound is placed at the bottom of a cylindrical
cell, at controlled temperature, and connected to a previously evacuated
space to which the pressure sensor is also connected. The compound is
then allowed to evaporate until the equilibrium pressure at the
temperature of the sample is achieved.
The vapor pressure was mesured to be 3.2 Pa at 20 °C, 32.3 Pa at 50 °C and 46.6 Pa at 55 °C .
