Any other information on results incl. tables
DMF is infinitely miscible with water and its vapour pressure is lower than that of water. It can be assumed that DMF shows very little tendency to evaporate from aqueous solutions.
Applicant's summary and conclusion
- Conclusions:
- Based on public data, the average vapour pressure of DMF (CAS no. 68-12-2) is 365 Pa at 20 °C or 490 Pa at 25 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
