Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Vapour pressure of tetrahydromethylphthalic anhydride (MTHPA) is estimated at 0.0028 mmHg = 0.373 Pa at 298K (25 degree C) by QSAR.
Key value for chemical safety assessment
- Vapour pressure:
- 0.373 Pa
- at the temperature of:
- 298 K
Additional information
The vapour pressure of tetrahydromethylphthalic anhydride (MTHPA) was calculated by 3 different QSAR models at 25 degree C:
- 0.00243 -0.00294 mmHg (MPBPVP v1.43 (Mean VP of Antoine & Grain methods)
- 0.00238 -0.00286 mmHg (AEROWIN v1.00)
- 0.0033 mmHg (Antonie equation)
The mean value of 0.0028 mmHg = 0.373 Pa was considered reliable in a Weight of Evidence approach.
