Vapour Pressure results – Reference Substance (Toluene)
In p = -A/T + B (p in Pascal; T in Kelvin)
A = 4810.009
B = 24.50073
From fit of measurements between -10.0 °C and 29.8 °C (liquid state)
Vapour Pressure at 20 °C: 3.3 x 103Pa
at 30 °C: 5.6 x 103Pa
Literature Values (guideline 104 OECD/198/105/12):
Vapour Pressure at 20 °C: 3.0 x 103Pa
at 30 °C: 4.9 x 103Pa
The measurement were done with two different saturation gas flow rates (1.7 l/hour an 3.2 l/hour), the saturation control was between the normal error limits for the gas saturation method.
Vapour Pressure results – Test Substance
In p = -A/T + B (p in Pascal; T in Kelvin)
A = 7439.155
B = 30.01732
From fit of measurements between -0.6 °C and 39.6 °C (liquid state)
Vapour Pressure at 20 °C: 1.0 x 102Pa
at 30 °C: 1.6 x 102Pa
The measurement were done with three different saturation gas flow rates (2 l/hour an 4 l/hour and 6 l/hour), the saturation control was between the normal error limits for the gas saturation method.
Phase Transition of Test Compound
No phase transitions were observed in the temperature region of the vapour pressure experiments, the substance is in the liquid state at room temperature.
