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.
