Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
