- Temp.:
- 20 °C
- Vapour pressure:
- 0.39 kPa
- Temp.:
- 25 °C
- Vapour pressure:
- 0.51 kPa
Any other information on results incl. tables
The vapour pressure curve (log p versus 1/T) was plotted. A line was fitted to the measured data (above 0.5 kPa) and the vapour pressure was back calculated from this line for 20 and 25 °C.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance was determined to be 0.39 kPa at 20C and 0.51kPa at 25C.
- Executive summary:
The vapour pressure of the substance was assessed according to EC (A4) using the isoteniscope method. The automatic vapour pressure tester was calibrated using ultra-pure water and determined the vapour pressure of the substance to be 0.39 kPa at 20C and 0.51kPa at 25C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
