Description of key information
The vapour pressure of MBB was 5.0 x 10(-8), 1.6 x 10(-7) and 3.7 x 10(-5) hPa at 20, 25 and 50°C respectively.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of 2-Methoxymethyl-p-phenylenediamine (MBB) was determined following the OECD 104 guideline.
Vapour pressure of the test material was determined by effusion method (vapour pressure balance) within the temperature range of 25°C to 82°C.
No vapour pressure of the test material was observed below approx. 60°C in effusion method. The vapour pressure ranged from 3.5 X 10-4 to 1.1 X 10-2 hPa, when measured at a temperature range of 63.7 to 82.4°C. These measurements were used to calculate vapour pressure at 20-50°C, using the Antoine equation.
The vapour pressure of the test material was (calculated using Antoine equation):
5.0 x 10-8hPa at 20°C
1.6 x10-7hPa at 25°C
3.7 x 10-5hPa at 50°C
