Description of key information
The calculated vapour pressures of the 5 aromatic sulphonic acids ranged from 1.95 to 69.8 Pa at 20°C
Key value for chemical safety assessment
- Vapour pressure:
- 69.8 Pa
- at the temperature of:
- 20 °C
Additional information
At 50°C, the measured vapour pressures of the 5 aromatic sulphonic acids ranged from 4.9 to 14.7 kPa. Since the measured values has been performed on 65% solutions at 35°C, to have a value to be used for the chemical safety assessment, the calculate values with EPIWIN (Modified Grain method) have been considered:
Benzene sulphonic acid: 16.7 Pa
p-Toluene sulphonic acid: 1.95 Pa
Hydroxybenzene sulphonic acid: 69.8 Pa
Xylene sulphonic acid: 27.9 Pa
Cumene sulphonic acid: 56.1 Pa
The more conservative value has been considered for risk evaluation
