- Temp.:
- 20 °C
- Vapour pressure:
- 0.038 Pa
- Remarks on result:
- other: at 20 ± 1°C, ± 1.73 x 10-4 Pa
- Conclusions:
- The vapour pressure at 20 ± 1ºC was 3.77E-2 ± 1.73E-4 Pa (N = 3, CV = 0.46%) using the spinning rotor gauge method.
- Executive summary:
The objective of this study was to experimentally determine the vapour presssure of the test substance at 20 ± 1°C using the spinning rotor gauge (SRG) method.
The mean measured background vapour pressure of the system by the SRG method was 1.57E-5 Pa at 20 ± 1°C. The mean measured vapour pressure of the reference substance, hexachlorobenzene, by the SRG method was 1.39E-3 Pa at 20 ± 1°C. This vapour pressure was consistent with published values. The mean measured vapour pressure of the test substance by the SRG method was 3.77E-2 Pa at 20 ± 1°C (N=3, CV=0.46%).
