- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Remarks on result:
- other: mean vapor pressure was 1.09E-4 ± 2.25E-5 Pa (N = 3, CV = 21%)
- Conclusions:
- The mean vapour pressure of the test substance was 1.09E-4 at 20ºC.
- Executive summary:
The vapour pressure the test substance was determined at 20 ± 1°C using the spinning rotor gauge method in accordance with OECD guideline 104. An approximate one-gram sample of the test substance was used for vapour pressure determination. A molecular weight of 182.17 g/mol was entered into the SRG program for the vapour pressure measurement of the test substance. The vapour pressure of the test substance was determined three times. The mean vapour pressure for the test substance at 20 ± 1ºC was 1.09E-4 ± 2.25E-5 Pa (N = 3, CV = 21%).
