Expiry date 29.01.2019
Storage Room Temperature (20 ± 5°C) - Key result
- Temp.:
- 20 °C
- Vapour pressure:

- Temp.:
- 25 °C
- Vapour pressure:
- 0.035 Pa

- Vapour pressure:
- 0.197 Pa
- Temp.:
- 60 °C
- Vapour pressure:
- 0.399 Pa
- Conclusions:
- For the test item 1,12-Diaminododecane, the following vapour pressures at 20 °C and at
25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 2.41 * 10-02Pa
Vapour pressure at 25 °C: 3.55 * 10-02Pa - Executive summary:
The vapour pressure of 1,12-Diaminododecane was determined according to OECD 104
resp. EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at four different temperatures. Three temperatures could be
evaluated as they showed reproducible weight loss. For these temperatures, 1/T was plotted
against log (p).
