Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Executive summary:
Vapour pressure130 Pa @ 148.5 °C (97% sulphuric acid). At 20 °C, the vapour pressure was 6 Pa (90% sulfuric acid) and 214 Pa (65% sulphuric acid).
Reference
Vapour pressure 130 Pa @ 148.5°C (97% sulphuric acid).
At 20 °C, the vapour pressure was 6 Pa (90% sulfuric acid) and 214 Pa (65% sulphuric acid).
Description of key information
The vapour pressure is dependent on the temperature and the concentration of sulfuric acid.
Key value for chemical safety assessment
- Vapour pressure:
- 6 Pa
- at the temperature of:
- 293 K
Additional information
At 20 °C the vapour pressure was
6 Pa for a 90% aqueous sulfuric acid solution
49 Pa for a 75% aqueous sulphuric acid
214 Pa for a 65% aqueous sulphuric acid solution
Tabulated below are the vapour pressure values for a range of concentrations of sulfuric acid. In the OECD SIDS, the concentration is not mentioned. However, as it is directly comparable to the result obtained by UK PSD at 148.5 °C the concentration of sulphuric acid in the OECD SIDS is most likely to be 97%.
